William Furno

• Arm Cannon: 3.0's Plasma Bow and Breakout's Plasma Gun are both used this way, particularly the latter in set form, as he doesn't have a proper "hand" pieces with it equipped. 2.0's Multi-Tool Ice Shield falls into this as well.
• Badass Biker: His 1.0 model has access to a weaponized motorcycle called the Furno Bike.
• Badass Cape: Wears a long black cape in his Brain Attack form, complementing his overall Knight in Shining Armor design.
• Blade Below the Shoulder: 1.0's Dual Fire Shooter has two flaming ones of these that can also shoot fire, which later gets used against him by Jawblade.
• Cool Sword: Brain Attack's Fire Sword, which deploys half of its blade when ignited.
• Deadpan Snarker: After becoming more serious in later episodes and less of a Fanboy for Stormer, he becomes a lot snarkier, especially during his rivalry with Rocka.
• Environment-Specific Action Figure: Breakout's underwater equipment, tailored specifically to let him hunt down Jawblade.
• Harpoon Gun: Breakout's Plasma Gun comes equipped with a Hydro Harpoon. Furno uses it effectively against Jawblade by tying his Hero Cuffs to it and getting them in range safely.
• Humongous Mecha: The Furno Jet Machine, which also has:
  • Weaponized Exhaust
• In-Series Nickname: "Young Blood".
• The Leader: Leads the team in Brain Attack, as well as a small group alongside Rocka in 3.0.
• Luckily, My Shield Will Protect Me: 2.0's Multi-Tool Ice Shield and Brain Attack's Fire Shield. The latter actually absorbs fire, allowing Furno to easily tank a flamethrower.
  • Hooks and Crooks: Furno's Multi-Tool Ice Shield in particular also has climbing blades.
• Noble Bird of Prey: His 3.0 design is modeled on an eagle, complete with a pair of small wings which allow him to fly.
• Playing with Fire: Predominantly utilizes fire-based weapons.
• Punny Name: His surname could be a play on either "inferno" or "furnace", both of which fit in with his fire motifs.
• Red Is Heroic: A Hero who is red.
• Rookie Red Ranger: Initially, but he grows out of it.

Preston Stormer

• Arm Cannon: Breakout's Plasma Gun.
• Backpack Cannon: Brain Attack's Ice Missile Launcher, which can be flipped up and fire flick missiles in set form.

• Brains and Brawn: He and Stringer are the Brains to Bulk’s Brawn.
• Cool Bike: Breakout's Ultra Mach Speed Cycle, which was never released as a set.

• Drone Deployer: His Breakout form is equipped with five Seeker Drones, which are stored on his arms and shoulders when not in use.
• Humongous Mecha: The Stormer Freeze Machine.
• An Ice Person: Most of his weaponry, though there are exceptions. He fits this in terms of personality initially, but takes a level in kindness in later seasons.
• In-Series Nickname: "The Pro".
• The Leader: There are occasions where he isn't the team leader, but he's always a voice of authority.
• Light Is Good: Has predominantly white armor and is one of the most veteran heroes.
• Luckily, My Shield Will Protect Me: 2.0's Multi-Tool Ice Shield and Brain Attack's Ice Hero Shield. Stormer's Ice Shield stands out thanks to its ingrained ice spears.
• Rhino Rampage: His 3.0 form is modeled after a white rhinoceros.
• Sword and Gun: His armaments in Breakout, a Plasma Gun and a Power Sword.
• Supporting Leader: Supporting as he may be, he still gets to fight against each saga's Big Bad at least for a little while. Breakout seems to subvert this, however.
• Swiss-Army Weapon: 1.0's Multifunctional Ice Weapon can project a blade of ice or shoot it like a projectile, and includes a small Circular Saw.
• Wolverine Claws: 3.0's Blades, which also double as a massive fist.

Mark Surge

• Arm Cannon: Breakout's Plasma Gun.
• Backpack Cannon: Plasma Shooters on Brain Attack's Jetpack Wings, although he needs to lean forward ala Boba Fett or be in-flight to fire them.
• Big Damn Heroes: Saves the day in Ordeal of Fire when he drives a hovertruck into the fuelling Fire Lord, severing his hand and knocking him out. And unlike the rest of the heroes, he was still in his 1.0 form at the time.
• Blue Is Heroic: A predominantly blue-colored Hero.
• Deflector Shields: Generated by 1.0's Lightning Shooter and Shield.
• Elemental Weapon: Breakout's Electricity Shooter. While it's the same piece as his Lightning Shooters, this one forms a blade from electricity.
• Freeze Ray: 2.0's Ice Spear Blaster. Notably, Surge was upgraded with this even though he'd already rode out the fight with the Fire Villains.
• Heroic Sacrifice: After Alpha 1 got cornered by the Fire Villains while trying to escort civilians to safety, Surge gave his team a diversion by destroying fuel cells, causing the villains to attack him in rage and allowing Alpha 1 to escape.
• In-Series Nickname: "Livewire".
• Jetpack: Brain Attack's Jetpack Wings.
• Lightning Gun: 1.0's Lightning Shooter and Shield and Brain Attack's Rotating Lightning Blades, the latter of which double as physical weapons.
• Shock and Awe: Predominantly uses lightning based weaponry.
• Spider Tank: The Surge and Rocka Combat Machine.

Natalie Breez

• Action Girl: She initially started out as a Faux Action Girl with little screentime, but starting with Ordeal of Fire, she gets to show us what she's made of, outright saving the day in Invasion from Below.
• Arm Cannon: Breakout's Plasma Gun.
• Battle Boomerang: 1.0's Energized Dual Boomerangs, which are essentially boomerangs with a pistol grip that can fire energy blasts.
  • Rocket-Powered Weapon: They have thrusters to avert Precision-Guided Boomerang.

• Blow You Away: Wind-themed.

• Friend to All Living Things: Given her ability to talk to animals, though she defies it for the Brain-controlled creatures.
• In-Series Nickname: "The Whirlwind".
• Jetpack: Breakout's Rocket Boots.
• Love Interest: She defies this, even going on Hero Factory FM to say under no uncertain terms that she's not interested in any of her teammates.
• Luckily, My Shield Will Protect Me: Breez is probably one of the more unusual examples, as she was one of the only 2.0's who didn't have this trope and instead picked it up for her Breakout form, before retaining it for her Brain Attack form as part of the Heroes' overall knightly aesthetic.
  • Beehive Barrier: Breakout's Hex Energy Shield is depicted as formed from hexagonal energy.
  • Deadly Disc: Brain Attack's Spinning Razor Saw Shield, which in the show can be retracted and extended.
• Product Placement: In series; the energy drink company Robo-Jolt asked Breez to be in a commercial for them.
• The Smurfette Principle: The sole girl among the Heroes.
• Punny Name: Named after "breeze", which is a type of wind.
• Spider Tank: The Breez Flea Machine.
• Sword and Gun: Breakout and Brain Attack.
• Tertiary Sexual Characteristics: Her Breakout design sports a unique feet design with prominent elevated heels.
• Wind Is Green: Wind-themed and green-armored.

Dunkan Bulk

• Arm Cannon: 1.0's Metal Sphere Shooter
• Backpack Cannon: Breakout's Missile Launcher.
• Blade Below the Shoulder: 3.0's Wrist Mounted Blades. Bulk notably gets one on each arm and has normal hands.
• Brains and Brawn: The Brawn to Stormer and Stringer’s Brains. That said, he's far from stupid, as he's the one to deduce the Brains' weakness.
• Drill Tank: The Bulk Drill Machine.
• Dual Wielding: His 3.0 Upgrade has dual Wrist-Mounted Blades.
• Environment-Specific Action Figure: The version of Bulk 1.0 that is packaged with Vapor has a jetpack and extra weapon.
• In-Series Nickname: "The Behemoth".
• Ironic Name: In Brain Attack he's easily one of the smallest and least bulky of the heroes.
• Jetpack: Briefly when he fought Vapor.
• Luckily, My Shield Will Protect Me: His high-Impact Shield from Brain Attack, the simplest design of them all.
• Plasma Cannon: Breakout's Plasma Gun.
• Sonic Stunner: 1.0's Sonic Boom Weapon.
• This Is a Drill: Brain Attack's High Speed Laser Drill, which also comes with a small missile.

Jimi Stringer

• Bears Are Bad News: 3.0 Upgrade
• BFG: His new Sonic Blaster in Breakout is absolutely massive, to the point that the weapon is shown being constructed instead of Stringer during the Breakout montage.
• Brains and Brawn: The Brains to Bulk’s Brawn.
• Cloudcuckoolander: Stringer, apparently. He winds up missing the climactic battle against Black Phantom in Breakout because he forgot where he'd landed his Hero Pod.
  He tends to get a little distracted at times, forget his gear in strange places, and lose track of time.
• Dark Is Not Evil: Stringer's primary color is black, with either orange or blue as a secondary highlight, but he's easily one of the nicest Heroes in the cast.
• In-Series Nickname: "The Supersonic"
• Make Some Noise: His weapons all have something related to sound, which can disorient any foe in the way.
• Named After Somebody Famous: His first name seems inspired by Jimi Hendrix.
• Shoulder Cannon: Breakout's Sonic Speakers sees him mount these into his shoulder armor, although they're not projectile functions.
• Sonic Stunner: 1.0's Sonic Boom Weapon and Breakout's Sonic Blaster fire orange sonic waves.
• Wolverine Claws: 3.0's Triple-Bladed Bear Claw, which replaces his right hand.

Nathan Evo

• Arm Cannon: 2.0's Ice Cannons on his Multi-Tool Ice Shield and Breakout's Plasma Gun, with a Tank Arm that enhances its power as well as his defense.
• Characterization Marches On: In Ordeal of Fire, he's portrayed as a meditator with a stereotypical Asian master voice. By his second appearance in Breakout, his voice has changed and he is portrayed as more inexperienced than before.
• Humongous Mecha: Evo XL Machine.
• In-Series Nickname: "The Steamroller".
• Luckily, My Shield Will Protect Me: 2.0's Multi-Tool Ice Shield, with Evo's being equipped with Ice Cannons.
• Punny Name: His last name is derived from "evolution", fitting with him being a demonstration of the more advanced new generation.
• Spider Tank: Evo Walker and Evo Spider Machine.
• Sticks to the Back: His Brain Attack upgrade has a sheathe on his back to hold his Vortex Staff.
• The Big Guy: He is a weapon expert often armed with the most powerful tools.

Julius Nex

• All Love Is Unrequited: He says in "Savage Planet Part 2" that he has feelings for Breeze, this fits the trope in that Breeze isn't looking for and doesn't need a relationship and it is never mentioned that he has feelings for her again.
• Arm Cannon: Breakout's Plasma Shooter, notable for being the only paired ranged weapon of the arc.
• Awesome Aussie: Speaks with an Australian accent and is a certified badass despite only being a rookie.
• Blade Below the Shoulder: 3.0's Double Bladed Tiger Claw. Unlike most of the 3.0 Heroes, it's not a case of Wolverine Claws and is attached to his forearm and doesn't replace his hand.
• Communications Officer: He's an expert in communications, including social media.
• Energy Weapon: Breakout's Laser Cutter, which includes a physical piece to depict its laser sight.
• In-Series Nickname: "The Tech-head".
• Luckily, My Shield Will Protect Me: 2.0's Multi-Tool Ice Shield. Nex's includes parallel claws.
• Nice Guy: He's openly friendly and helpful, which makes sense given his expertise in social networking.
• Panthera Awesome: His 3.0 Upgrade is based on a tiger.
• Punny Name: His last name is derived from "next", as in next-generation Hero.
• Stealth Pun: He is colored orange, making him an "orange Julius".

Daniel Rocka

• Arm Cannon: 3.0 XL's Blaster, notably the only shooting weapon of the heroes in that arc.
• Automatic Crossbows: Breakout's Crossbow, which is fed from a bandolier of "arrows" (minifigure spears).
• Beehive Barrier: Breakout's Hex Energy Shield, which can materialise the hexagonal energy as needed.
• Characterization Marches On: Rocka does this more often than Evo. In 3.0, he's essentially Furno 2.0. In Breakout, he's revealed to be working undercover as a member of the Hero Recon team, which is one heck of a promotion. By Brain Attack, he's just another member of the gang.
• Cool Sword: His Plasma Sword from Brain Attack.
• Gadgeteer Genius
• Humongous Mecha: Rocka Stealth Machine and Rocka Crawler.
  • Arm Cannon: Rocka Stealth Machine.

  • Invisibility: Rocka Stealth Machine.
  • Power Pincers: Rocka Stealth Machine.

• King of Beasts: 3.0 Upgrade.
• The Leader: Co-lead a group with Furno in 3.0.

  • Deadly Disc: Brain Attack's 360 Degree Spinning Razor Shield, which has twin retractable blades.
• No Name Given: In merchandise and the TV series, he's never referred to by his first name, but its revealed to be "Daniel" in some versions of the credits of Savage Planet and Brain Attack. However, LEGO confirmed that it wasn't canon.
• Remember the New Guy?: In Savage Planet, Furno seems to know enough about Rocka to object to the latter being called "the new Furno." Rocka is said to have been built with the upgrade, making him a then-recent addition to the cast, but we only meet him after he had done so many heroics to gain his new title.
• Spider Tank: Surge and Rocka Combat Machine
• Underestimating Badassery: He captured Voltix easily, believing that it was due to his new upgrade, but didn't realise that Voltix had planned on being captured in order to enact the breakout.
• Wolverine Claws: 3.0's Double Claw, modelled after a lion's paw. It becomes much larger when he's upgraded into Rocka XL.

Thresher

• Guns Akimbo: He wields a large cannon on each arm.
• The Leader: Former leader of Alpha 1 Team.
• Retired Badass: Was once Alpha 1's leader.

• The Leader: Of Delta 9 Team

• Toyless Toyline Character: None of them received any toys.

Akiyama Makuro

• Big Good: As the founder of Hero Factory, he is the one responsible for the creation of all of the heroes of the series.
• What Could Have Been: Christian Faber the co-creator of Toys/Bionicle and Hero Factory has stated that Makuro was considered to be a Turaga or Toa from the Bionicle universe who was displaced from his original reality through an incident involving the "Well of Time," and realizing a need for heroes in his new universe founded Hero Factory as an imitation of the Toa he was familiar with. It seems the concept never got far beyond the pitch stage, and is canonically dubious at best... although it certainly makes Makuro's face looking so much like a Bionicle Noble Mahiki mask seem like less of an accident and more of an intentional arc tease.

Professor Zib

• Butt-Monkey: A lot of humor is derived from him being put into misfortune.
• Mission Control: He's the Chief Mission Manager.

Quadal

• Cyber Cyclops: A robot cyclops.
• Mission Control: Together with Zib.

• The Von Trope Family: Von Ness and Von Nebula.

Xplode

• Arm Cannon: His Meteor Blaster
• Carry a Big Stick: His blade is described as a club.
• Gentleman Thief: Partially; Xplode is actually wealthy and takes on jobs for the challenge. However, his manners, attitude, and actions are far from a conventional example.
• Gun And Sword: Armed with a blade in hand and his trusty Meteor Blaster.
• Having a Blast: All of his weapons are usually explosive.
• Macross Missile Massacre: Can launch his spikes as missiles.
• Spikes of Villainy: And weaponized.

• Energy Absorption: All mining bots were given this ability to cut down in traveling times to refuel, but without safeguards, it drove them insane.
• Evil Feels Good: According to Fire Lord, they like what they have become (that is to say, insane).
• Foil: To the 2.0 Heroes. Both are the first Heroes and villains built with the new system that uses new technology in-universe, but that's where their similarities end. The Heroes are a uniform team that are smaller than the larger and more varied Fire Villains, using ice weaponry to counter their fire powers. The Heroes' upgrade was done so cautiously, with the Heroes being tested within the timeframe the crisis permitted by their superiors personally and affected them physically, while the Fire Villains' upgrades were done so out of negligence and convenience by unseen executives and affected them mentally.
• Phlebotinum Muncher: Fire Lord and his minions do this to increase their power (and insanity).
• Playing with Fire: It's in the name.
• Spikes of Villainy: All of them have spikes on them and they are villains..

Fire Lord

• Big Bad: The main villain of the Ordeal of Fire storyline.
• Blade Below the Shoulder: His Lava Blaster
• Card-Carrying Villain: He calls himself evil and says that he likes what he has become.
• Evil Is Burning Hot: Quite obviously.
• Harmful to Touch: Well, he's Evil Is Burning Hot, so...

  The leader of the fire villains hates to be touched. Even if someone wanted to touch him, his incandescent personality would be burned into them, along with second degree burns.
• Jetpack: His method of flight.
• Large and in Charge: The largest of the Fire Villains and their leader.
• Red and Black and Evil All Over: Is primarily black with red fire to serve as a secondary color, and he's a Card-Carrying Villain.
• Sword and Gun: His right arm has his Lava Blaster (which can function as a sword) and his left arm has his Lava Sphere Shooter.
• Volcanic Veins: Every time he absorbs energy, he gains veins.

Nitroblast

• Ammunition Backpack: His Claw Blade is connected to his backpack presumably as a power source.

Animal Slaves

• Big Creepy-Crawlies: Waspix is a giant robot wasp.

• Going to Give It More Energy: His big plan to finally defeat Hero Factory? Plug himself up with the energy from the hero building room to gain all the power he needs.

• Killed Off for Real: In an alternate dimension.
• Spikes of Villainy: His robot half has green spikes sticking out of it.
• Split Personality: His defining trait, as a result of being Two-Faced— the robotic and organic sides of his brain don't integrate properly. In the flashback story Legion of Darkness, one side is reckless and the other is cautious, while in later stories he descends into Talking to Themself. Each personality has its own weapons, too.
• Talking to Themself: He does this— out loud, no less— in Breakout and the chapter book The Doom Box. Oddly enough, he doesn't demonstrate this in the flashback chapter book Legion of Darkness, suggesting that while he's always had a Split Personality, the madness only progressed later.
• Two-Faced: His entire body is divided into two separate colored and styled halves.

• Power Pincers: His Core Remover.
• Red and Black and Evil All Over: His primary color is black with red accents.

  • The first episode states that, as the hero's core is their main processing center (analogous to their brain), which means that not getting a replacement results in the body dying. The personality either dies or becomes a case of And I Must Scream, presumably.
• Shadow Archetype: It's subtler than Von Nebula, but his struggle with staying on the straight and narrow path of his intended programming makes him one for Surge, the one 'bot who is consistently characterized as being unsure if he can measure up to the high moral standards of his job. Driven home when Surge is the one to ultimately defeat him.
• Spikes of Villainy: Big curved red spikes are all over his body.

Artificial-created, organic parasitic creatures with one goal in mind: destroy Hero Factory.

• Flight: In an alternate dimension.
• Spikes of Villainy: Have two-to-three spikes on them, which also serve as their weakness since hitting them will free the controlled creatures.
• Transformation of the Possessed: The wildlife they controlled were also mutated into horrifying monstrosities with Elemental Powers and Elemental Armor. Fortunately, removing them reverts their victims.
