The Casket family
The main hero of the game. Mega Man works together with Roll as they investigate ruins as Diggers, Mega Man doing the adventuring while Roll provides info of what to do. His otherwise normal life (for this world, at least) is gradually dissolved, however, as the two games reveal his Mysterious Past. In reality, he is Mega Man Trigger, a Purifier Unit for the System, and his actions tie into the fate of the System, and the planet and its population.
- Arm Cannon: Naturally, but in this case, he can have two at a time, his normal Buster on the left arm and his special weapon on the right. Given his history, his primary might or might not be part of his body or part of his armor.
- Ambiguous Robot: In the first game, it's not entirely clear throughout it whether he's a robot or a kid wearing Power Armor. He's eventually confirmed as a Ridiculously Human Robot.
- All-Loving Hero: No one and nothing is above his compassion; not even the villains. When he finishes blasting them, he usually expresses remorse over doing it.
- Badass Adorable: Much like his original counterpart.
- Charged Attack: Had the traditional Charge Shot in Tatsunoko vs. Capcom, but not yet in any of the actual Legends games. The design team had an idea on how to implement it, though.
- Chick Magnet: Roll and Tron are both head-over-heels in love with him, but we also have Yuna, and probably Sera. There's a piece of official art of Volnutt getting crushed as all four of the girls try cozying up to him at once.
- Covert Pervert: Walks in on a nude Roll once per game and is seemingly pleased with himself for doing it. Inspecting a magazine rack in the first game as him mention some dirty magazines, but he doesn't feel comfortable looking at them with other people around.
- Crossdressing Voices: In both Japanese and English, though only in 2 in English, he has a female voice actress.
- Dark and Troubled Past: His past as a Purifier Unit involved with an insurrection years ago comes to light in Legends 2.
- Expy: Of the original Mega Man, in tradition as a Legacy Character. His backstory however makes him something of a counterpart to Zero, given his sealing in stasis and revival to fight against the system he helped bring into power.
- Frickin' Laser Beams: The Shining Laser is his most powerful weapon, able to rapidly deplete any opponent's health in seconds (if they let him hold still to aim it).
- Good Is Not Soft: He's an All-Loving Hero who feels compassion for the villains and helps anyone in need. But when it's time to fight, he will kick your ass.
- Helmets Are Hardly Heroic: He is the only Mega Man incarnation who doesn't wear a helmet by default. While he can wear one in both games, don't expect to see him wearing one in any other appearances.
- The Hero: The main good guy, which in his game, means going into dungeons and battling Reavers while the rest support him from the Flutter.
- Laser-Guided Amnesia: Because he had to be reset to infant form following his battle with Sera, his memories were downloaded into Data for safekeeping. Mega Man remembers nothing of the System until the end of Legends 1 and into the sequel.
- Love Triangle: With Roll and Tron. He can be considered the Archie to Roll's Betty and Tron's Veronica.
- Macross Missile Massacre: Several missiles let him rapidly fire out missiles and bombs.
- Multi-Ranged Master: His arsenal of weapons is enormous, including a variety of bomb and missile launchers, lasers, and energy projectiles. His Blade Arm even allows him to fire Sword Beams.
- Nice Guy: A defining trait is how gosh darn nice and heroic he is. In the first game alone, he can donate to the town reconstruction fund, save a pregnant woman lost in the woods that goes into labor, donate to the hospital to help heal a crippled girl's leg, help the police with their cases, and of course, stop the Bonnes from causing chaos.
- Nice Job Breaking It, Hero!: Though accidental, Mega Man is directly responsible for the main crises in both games. In the first game he awakens Juno, who goes on to attempt to destroy Kattleox, and in the second game he releases Sera from statis and then finds her the Keys she needs to activate the Carbon Reinitialization Program and wipe out all the Carbons on Terra.
- One-Man Army: The Bonne family have a fleet of airships and giant robots. The Casket family has Mega Man. That's all they need. It's practically lampshaded when Mega Man deals critical damage to the Bonnes' lead airship, and Teisel exclaims "what kind of firepower are they packing on that little ship?" According to the backstory, he waged a one-man war on Elysium, and it took Sera, a Mother Unit, to bring him down. And even then it was more of a stalemate.
- Oblivious to Love: He is oblivious of any affections directed towards him by any of the female characters.
- Oh, Crap!: He gets this reaction in the first game when the first boss suddenly comes back to life and follows him outside of the prelude dungeon.Mega Man Volnutt: Back for more!?
- Powered Armor: Maybe? Mini-Mecha and cybernetics are common, but no one else has power armor that streamlined, so it's unclear whether his armor is powered or not. He's definitely replacing his right arm with the special weapons, as some of them are too short for his forearm to fit.
- Really 700 Years Old: Barrell found him sealed in a ruin, so it's hard to tell how old Volnutt really is. His current form is a result of resting his body to a state of infancy who-knows-how-long ago, after his first bout with Sera left him critically wounded. Even before then, he was serving the Master on Elysium as a Purifier Unit for what may have been centuries.
- Ridiculously Human Robot: Unlike the other characters, who are mostly humans that can become Cyborgs, Mega Man is a robot.
- The Scrounger: Operates as such unofficially due to his work as a dungeon-raiding scavenger, both finding useful items for Roll to cobble together into usable weapons and equipment, as well as an optional sidequest in the first game as "Requisitions Officer" for a group of children hoping to renovate an old building to use as a clubhouse.
- Swiss Army Appendage: While his right arm is always equipped with his handy Mega Buster, his left arm can be fitted with such attachments as machine guns, drills, and even the Z-Saber/Zetsabre.
- Trademark Favorite Food: Pizza.
- Transferable Memory: Trigger stored the memories of his past life, along with any essential files, in Data, making sure that Sera would not obtain The Master's genetic code.
- Trauma-Induced Amnesia: Justified due to the above statement, but it wasn't a direct result of trauma.
- Unresolved Sexual Tension: With Roll; it's obvious they have feelings for each other, but nothing comes of it.
- Unwanted Harem: As seen in this◊ official art, Roll, Tron, Sera, and Yuna all have some degree of feelings for him, and he wants none of it.
- Worthy Opponent: To both the Bonne Family and Sera. Over the series they develop a grudging respect for him.
- Would Hit a Girl: He came to blows with Sera in the backstory, and pulls no punches when fighting Tron in her robots. In Legends 2, you can attack Roll in the game's first areas.
- Remember the first time you went on a dig, Mega Man? I wasn't used to being a Spotter... and you ended up getting lost underground for three days! Remember? We were lucky that Gramps came to help us... I don't know what I would've done if he hadn't been there...
Mega Man's Spotter, in charge of building and maintaining his equipment. Years ago her parents went missing on a dig, and Roll hopes to find out what happened to them someday. In the meantime she provides Mega Man with advice on his missions and also pilots their airship, the Flutter.
- Ace Pilot: If it moves, she'll know how to pilot it. Boat, spotter car, airship, train? Not a problem for her. Played with in the first game, where if she hits Mega Man with the spotter car in one sequence, she apologizes and claims she's not used to driving it yet.
- Adaptational Badass: The original Roll started out as a minor character but gradually became an Ascended Extra and earned playable appearances as a Badass Adorable Lethal Joke Character in other games as the classic series evolved. The Roll of Mega Man Legends is an Ace Pilot, Gadgeteer Genius, and Mission Control right from the start.
- Betty and Veronica: The sweet and nice Betty to Tron's Tsundere Veronica, for Mega Man.
- Expy: Of the original Roll.
- Cannot Spit It Out: Her final journal entry in Legends 2 outright states (if you were nice to her during the game) that she's realized she loves Mega Man, but she never tells him.
- Gadgeteer Genius: Found some old broken drill or toy laser sword? Take it to Roll and she'll figure out how to make a new weapon out of it! As the Abridged Series puts it: "Builds WMDs out of junk."
- Mission Control: She's Mega Man's spotter in the Flutter and relays him data she gathers about the area as he explores.
- Parental Abandonment: They disappeared on digs, so she was raised by her grandfather.
- Romance Sidequest: Both games have the option to bring her various gifts to improve her affection rating.
- Shorttank: A video game example of this trope.
- She's Got Legs: Rivals Tron in that department, further emphasized by her wearing short shorts, showing them off.
- Teen Genius: She does all of the above as a teenager.
- Voice with an Internet Connection: How she communicates with Mega Man while he's underground.
- Wrench Wench: She can't help herself. She saw a broken boat in the first game and spontaneously decided to fix it.
- Who Wears Short Shorts?: Wears red shorts, showing off her legs.
- Hi! My name's Data! But you already knew that, didn't you? I mean, we've been friends for years, right? Come talk to me if you want to save, ok?Voiced by Ikue Otani (Japanese)
The crew's mascot found together with Mega Man. He has ever since tagged along with them. He's the storehouse for Mega Man's lost memories, holding all his knowledge of Elysium, the System, and his past.
- Big Damn Heroes: At the end of the first game, he shows up out of nowhere and prevents the extinction of all the people on Kattelox Island.
- Chekhov's Gunman: His appearance at the end of the game to save Kattlelox suddenly makes it clear he's far more important than just being the guy you visit to save your game.
- Everything's Better with Monkeys: There's no explanation given for why Data is a monkey, given his purpose.
- Meaningful Name: He acts as your save point. He also holds data on Mega Man's previous life.
- Neuro-Vault: He's Mega Man's backup unit that holds all his lost memories.
- Non-Human Sidekick: He helps Mega Man with save points and health recharges.
- Team Pet: For the Casket Family, as their faithful monkey companion.
Barrell Casket is Roll's grandfather and was an avid Digger in his days. He raised Roll and Mega Man.
- Anti-Villain: They may be pirates, but they aren't monsters. Their interest is making money, not deliberately hurting people or causing destruction; that's just the side effect of piracy. Any time there's serious danger going on, they have no problem working with Mega Man to try and stop it.
- Badass Family: The three of them command a small arsenal of robots in all sorts of designs, and fielded an entire airship fleet before Mega Man shot it down.
- Big Bad Wannabe: Managed to swing between this and Big Bad. The Bonnes are Mega Man's most persistent and recurring foes, and are the main antagonists of the first game. However, they're far less of a threat than the System units, and are often too ineffectual or comical to see as all that dangerous.
- Bullying a Dragon: They keep on picking fights with Megaman, even after he destroyed their raiding party, ground forces, digging machine, battleship, armada and mothership. They managed to escape on the Focke-Wulfe but instead of just cutting their losses, they still insist on taking the guy who practically demolished their entire forces single handedly and paid the price.
- Enemy Mine: They repeatedly go through the motions of villainy - invasion, property destruction, pillaging - and get trashed by Megaman. At some point, however, they stumble into the middle of something that could get lots of people killed for no reason at all and immediately offer him their unconditional support because they don't want to be collateral damage and are seriously freaked out by the mindless destruction sought by worse villains.
- Ineffectual Sympathetic Villain: They try to be genuine menaces, but are too incompetent and silly to see as one. At the end of the first game when they escape with a giant refractor, odds are you'll be happy for them because at least something went right for them at last.
- Punny Name: Their names are pronounced "bon," making Bon Bonne's name sound like a candy, fitting for a baby. Teisel and Tron on the other hand fit with the alternate pronunciation "bone," for T-bone and Tro(m)bone. Together with Glyde, their names are a reference to Bonnie and Clyde.
The leader of the Bonnes, he's always on the lookout to score some treasure. After what is initially just another job goes south due to Mega Man's interference, Teisel declares It's Personal and makes it his mission to someday defeat Mega Man no matter the cost.
- Affably Evil: He seems like a pretty fun guy to be around, if you're not his enemy.
- Anime Hair: You don't get spikes like that in the real world.
- Big Bad: Of a Chinese PC game called Rockman DASH: Adventure to Save the Planet.
- Disney Death: He gets knocked off the Gesselshaft before the final boss in Misadventures. After beating the boss, he's shown to be perfectly fine, just a little soaked.
- In Legends, he and his siblings also have one following Mega Man defeating them in the Focke Wolf boss fight. They survive, much to Mega Man's relief.
- Distressed Dude: He and Bon Bonne are kiddnapped after Misadventure's first playable segment.
- Even Evil Has Standards: Self-invoked in the second game, as they loot a town of almost everything of value.Teisel Bonne: We may be pirates, but we're not barbarians. We'll let them keep the toilet paper.
- Evil Is Petty: He absolutely refuses to get involved with the battle, he left it to Tron and Bon to handle... then a news broadcast of Mega Man's heroism interrupts his favorite TV show. Cue Jaw Drop and eventual outrage.
- Face Death with Dignity / Graceful Loser: When Mega Man damages the Focke Wolf (a flying mecha currently over the clouds) beyond repair, and everybody thinks the Bonnes are about to fall to their deaths, he comforts Tron by saying, "You tried your best, and sometimes that's not enough, but it's all you can be asked to do. He beat us fair and square. That's how life is sometimes."
- Guest-Star Party Member: He's the person piloting the Gustaf at the start of The Misadventures of Tron Bonne, with Tron acting as his spotter. He's quickly kidnapped. During the final segment of the game, both Tron and Teisel are inside the Gustaf, as shown by them fighting for space on the pause screen.
- HeelFace Turn: Attempts one in Legends 2 in running a store, but the store itself goes so deep into debt that he has to return to piracy in order to pay off what he owes. He laments this before the fight against him.
- It's Personal: After the Evil Is Petty moment above, when Mega Man destroys the Marlwolf, Teisel makes it his mission to defeat him as a matter of principle.
- Large Ham: Teisel has three tones of voice — talking normally, shouting, and shouting louder. The first does not get used nearly as much as the other two.
- Loveable Rogue: He may be a pirate but he's so darn funny!
- Manipulative Bastard: Near the end of Legends 1, he manages to smooth talk Mega Man into letting him go by claiming that he's giving up, but he's just decided to wait for Mega Man to open the Main Gate for him so Teisel can get its treasure. He also claims, at the end of The Misadventures of Tron Bonne, that he wanted Lex Loathe to force him to be a miner to work off his debt, because Loathe's mining facility is the location of yet another legendarily huge refractor.
- No Indoor Voice: "I SAID, clo-o-o-ose the HATCH!"
- Red Eyes, Take Warning: He has red eyes, ostensibly due to cybernetics.
- Strong Family Resemblance: He looks almost exactly like his father...if it weren't for the red eyes and crazy hairstyle.
- Suspiciously Similar Substitute: He's the Legends stand-in for Dr. Wily, Mega Man's arch-enemy who battles him with an army of robotic minions. His hair and red eyes call to mind Wily's design, and the Bonnes share their skull emblem motif with Wily, though the designs differ.
- Worthy Opponent: Although Teisel's early defeats by "a mere blue boy" invoke This Cannot Be! reactions, he eventually starts to see Mega Man as this after the Bonnes' best efforts continue to be thwarted by him.
The Bonne Family's main engineer who builds all their robots. Due to Mega Man saving her from a dog, and just his general heroism, she eventually develops a crush on him. But family comes first, and even if she doesn't like it, she's still going to fight Mega Man to do right by them. She has her own title, The Misadventures of Tron Bonnne.
- Animal Mecha: Most of the major robots she builds fit into an animal theme.
- Anime Hair: Not as out-there as Teisel's, but it's still pretty silly. Even more so when she's not wearing her hairband.
- Because You Were Nice to Me: Her crush on Megaman stems from the act of kindness he showed her in the first game by saving her from a dog.
- Betty and Veronica: The Veronica to Roll's Betty towards Mega Man.
- Bishōnen Line: Her "masterpiece", Theodore Bruno, is the most humanoid of her robots and definitely the strongest.
- Breakout Character: Along with Mega Man himself, she's the character everyone knows from this series. She got her own spinoff for a reason.
- Coming-of-Age Story: Misadventures is this for her in Teisel's eyes. When they're reunited, he realizes that his sister isn't a child anymore.
- Dark Action Girl: A young woman who is an expert mecha pilot and can wipe the floor with Mega Man.
- Disney Death: She's caught in an explosion near the end of Misadventures and taken out of commission, requiring a Servbot to fight the final boss.
- She and her brothers also have on in Legends, where it looks like they perish in the Focke Wolf. To Mega Man's relief, they survive.
- Distressed Damsel: In Misadventures, she's kidnapped near the end of the game. A Servbot drives the Gustaf solo to rescue her.
- Evil Counterpart: To Roll, as the weapons expert of the Bonnes who builds and pilots their robots.
- Friendly Enemy: Towards Denise in The Misadventures of Tron Bonne. She's always eager to offer a few comforting words whenever she defeats the latter. She also has shades of this with Roll by the ending of Legends 2.
- Loveable Rogue: Just like Teisel, she's very likeable for a pirate.
- Mama Bear: She refers to the Servbots as her kids, and after Mega Man beats them up in a boss battle she vows to take him down.
- Mission Control: During Teisel's short stint as a playable charcter, she acts as his spotter.
- Opaque Nerd Glasses: Wears these whenever she's working in her lab.
- Paper-Thin Disguise: Wears one in Legends 2 by changing clothes and donning a pair of (non-opaque) glasses.
- She's Got Legs: Damn.◊
- Standard Female Grab Area: Happens to her twice from Glyde in Misadventures and even has a portrait for it.
- Strong Family Resemblance: She looks exactly like her mother.
- Team Mom: For the Servbots, who look up to her and attend her.
- Teen Genius: She may be a teenager, but she has the skills to build and repair robots the size of houses.
- Tsundere: Normally very hot-tempered and angry, but she has a soft side that comes out sometimes, especially when dealing with Mega Man.
- Villain Protagonist: During the prequel, as she's the player character for 99% of the game (though you actually control her mech, not her directly, unless one counts the static image of her at the base).
- Villainesses Want Heroes: She wants Mega Man Volnutt.
- What Is This Feeling?: Tron can't figure out why she feels funny every time she thinks of Mega Man in the first game, nor can she figure out why she isn't furious with being unable to destroy him.
- Why Did It Have to Be Snakes?: Fears dogs a lot, to the point she'll jump to a lightpost from the smallest puppy.
The youngest member of the Bonne Family, who only speaks in "Babuu." Despite being the kid of the family he has tremendous strength.
- Ambiguously Human: Is he a baby perpetually inside a mecha, a child-like robot treated like family, or a baby that's been made into a giant Cyborg? No one really knows.
- Big Damn Hero: He stops Glyde from taking out both Teisel and Tron after his rematch fight in Misadventures.
- The Big Guy/The Brute: Lacks the engineering skills of Teisel and Tron, and doesn't possess the dexterity to use machinery as the Servbots can. Instead he uses himself, either with Super Strength and built-in weaponry in one-on-one combat, or as an engine to the Bonne's machinery.
- Disney Death: Along with his siblings after the Focke Wolf boss fight in Legends.
- Intelligible Unintelligible: Somehow Teisel and Tron seem to understand what he's saying even when he's just saying "babuu" over and over.
- Macross Missile Massacre: He can fire a salvo of missiles during the first encounter with him.
- Made of Iron:
- In Misadventures, his head gets blown off in the prologue and is completely whole again when he's seen again later.
- In Legends 2, he sinks into some lava in the third main dungeon, yet appears soon after fit as a fiddle.
- Power Floats: While he does have a ground-based body, when fought in battle he tends to fly around.
- Super Strength: In the first game, one of his basic attacks is to just clap his hands with Mega Man between them, crushing him. In the second game, he's the engine for the Bonne-Glyde train, pulling them along the track so fast they actually outpace Mega Man and Roll in an actual locomotive.
The adorable Bonne family minions, built by Tron. There's forty-one in total, and they pilot the family's robots and airships. This usually means they end up blown up and thrown around when Mega Man destroys that robot, after which they're usually yelled at by Tron. Even though they always go through hard times, they do their very best to make their mom (Tron) proud of them, which sadly happens very rarely.
- The Dragon: The favorite essentially acts as this to Tron.
- Guest-Star Party Member: There's a casino Mission the favorite Servbot can undertake if Tron elects to take a nap. During the final Segment of the game, Tron is kidnapped and the Favorite Servbot drives the Gustaff solo to rescue her.
- Invincible Minor Minion: In Misadventures, you are required to exploit this by having them walk into otherwise dangerous situations.
- Iron Butt-Monkey: Blow up their robots, shoot them up, kick them around. They're indestructible no matter what abuse they may take..
- Mascot Mook: Similar to the Mets for the rest of the series, everyone recognizes the Servbots.
- Took a Level in Badass: The Favorite Servbot becomes the Player Character when Tron's kidnapped.
- Trademark Favorite Food: Curry.
- You Are Number 6: They tell each other apart by number.
The self-proclaimed rival to the Bonne Family. Teisel is his main rival and both hate each other's guts. He's served by the Birdbots, his loyal bird-themed robotic minions.
- Ambiguously Gay: He has a soft voice, is very well groomed, and walks around with a rose.
- Never Found the Body: He is never seen or heard from again after Legends 2's train battle when his train car explodes, leaving his ultimate fate ambiguous. Given how much abuse the Bonnes themselves take, though, he probably survived.
- The Rival: To the Bonne family. He and Teisel don't get along at all.
- Smug Snake: He's far too confident for his own good, even when things begin to turn against him.
A loan shark that eventually kidnaps both Teisel and Bon for a huge debt Teisel never paid him back.
- Big Bad: Of The Misadventures of Tron Bonne.
- Loan Shark: Demands interest of 2 million zenny after Tron pays back Teisel's initial 1 million zenny loan, then demands interest on the interest!
- Shout-Out Theme Naming: He seems to be named after Lex Luthor.
- What Happened to the Mouse?: His fate is unclear after The Misadventures of Tron Bonne, especially since his minion Glyde is doing well in Legends 2 without him.
Two pirates that are also after the Keys in Legends 2. Both of them claim to be old and past their prime, but are still very tough to take town.
- Affably Evil
- *Crack!* "Oh, My Back!": Word for word in the fight with Klaymoor. He hastily retreats thereafter.
- Know When to Fold 'Em: Bola more than Klaymoor, but both have this attitude. The pair jumps ship from the pirate alliance once it's clear they're just going to get thrashed by Mega Man again.
- One Last Job: Both are retired and long past their prime, but join up with the alliance due to Klaymoor's lifelong dream of finding the Motherlode.
- Retired Badass: Bola implies the pair is long past their piracy days and fairly well off from it.
- Theme Naming: Both are named for weapons (in the international versions).
- Tin Tyrant: Klaymoor is wrapped in a giant suit of armor.
- Villainous Friendship: Though they bicker, Bola & Klaymoor are lifelong friends. Bola admits right out he has no need for the Motherlode, but tagged along to help out his friend.
- You Gotta Have Green Hair: This even extends to his crew!
An extremely devoted police officer who always has bad days during work. She tries really hard in bringing criminals to justice by all means necessary.
- Butt-Monkey: Repeatedly fails to apprehend Tron, frequently gets in trouble with Da Chief, and is usually buried in paperwork.
- The Cameo: She shows up as a weather reporter in Mega Man Megamix.
- Charles Atlas Superpower: She can flip the Gustaff over her shoulder with her bare hands.
- Failure Hero: No matter how hard she tries, she just can't seem to stop Tron's various heists and destructive antics.
- Fair Cop
- Hero Antagonist
- Not a Morning Person
- Throw the Dog a Bone: At the end of The Misadventures of Tron Bonne, Tron drops Mr. Loath and Glyde in her office, which is enough to trick Da Chief in thinking she caught them. Of course, she's now stuck writing another report on how she did it.
A man living on Calinca Island, he's determined to someday explore the nearby Forbidden Island. He has no memory of his past but lives comfortable on Calinca in spite of it.
- Arm Cannon: His right arm has a cannon on it.
- Laser-Guided Amnesia: He has no memories due to what happened on Forbidden Island.
- Luke, I Am Your Father: Though not outright stated in-game, it becomes very obvious he is Roll's long-lost father Banner.
- Red Right Hand: His right arm is cybernetic.
- Starting a New Life: He eventually lets go of his mysterious lost memories and decides to start a new life with Calinca's bartender Maria.
- Swiss Army Appendage: According to concept art, his cybernetic arm's fingers host various tools including screwdrivers and a wrench.
- Tragic Keepsake: He keeps a picture of the family he doesn't remember with him.
- Voiced by Kent Sheridan (English)
The last true human alive, who lived in paradise on Elysium. Realizing the System that was sustaining him was wrong to support, he went to Terra to die peacefully and asked Mega Man to shut down the System.
- Dude Looks Like a Lady: This◊ is the master. Would you know without being told that's a guy?
- Go Out with a Smile: He died happy and peaceful.
- Last of His Kind: He is the last original human; all the humans you interact with are artificial humans called Carbons.
- The Master: A rare heroic version, or at least not evil.
- Posthumous Character: He's long dead by the time the games begin.
- Really 700 Years Old: He's 3000 years old.
- Walking Spoiler: His role in the story requires the spoilering of a lot of end-game plot details to talk about.
A Bureaucratic unit who rests beneath Kattelox Island within the Main Gate, he is awakened by Mega Man when he explores the gate. His function is to monitor the population of the island, and when it is judged to have grown too large, he "reinitializes" it — meaning killing everyone.
- Affably Evil: Unfailingly polite. Courteous to what he believes are his superiors. Tries to help what he thinks is a malfunctioning unit. Treats genocide of the Carbons like it was taking out the trash.
- Big Words: During their final battle, his first statement is that he's going to "exercise my prerogative of correctional dispensation". This confuses Volnutt so badly that he has to rephrase it to "I'm going to exercise my authority to terminate your program."
- Deader Than Dead: His physical form is destroyed and his back-up data deleted.
- Dissonant Serenity: Always talks in a calm, soft voice, even as he tells Mega Man he's going to wipe out the island's populace, and then electrocutes him to trap him so he doesn't interfere. Subverted when he goes One-Winged Angel and starts screaming hammily.
- Eyes Always Shut: He only opens his eyes once when he's reactivated, though they do change shape with his expressions when closed.
- Expy: Of Sigma. Both leave their heads behind after being defeated the first time, which then flies up and attaches to a larger body. Also like Sigma he plans to wipe out "carbons" with Eden, but it's not for the sake of evolution rather due to the number of humans currently living on the island.
- Also, Juno reminds some players of Xelloss from the Slayers series, from the perpetually closed eyes to the creepy carefree smile. Both characters are also voiced by Akira Ishida.
- He also got an expy of his own a few years later. Lumine from Megaman X8. Both have purple hair, both have a creepy carefree smile, both have similar color patterns (white and purple), both are affably evil villains that act nice to the heroes at first but then try to kill them, both of them want to wipe out humanity(for different reasons, though), both get revealed as hidden villains at the end of their respective games after usurping the role of Big Bad from another villain(Sigma and Captain Bonne, respectively), both don't have many appearances in their respective games despite being the final boss and both have a loose Light Is Not Good theme to their final boss battles(both of them are dressed in white and purple and Juno has organ music blasting off in the background of his final battle while Lumine transforms into an angel-like form for the second phase of his final battle). Lumine also has organ music play during his boss battle theme, but only during the first phase.
- Final Boss: In Legends 1.
- Floating Limbs: His arms and hands float separate from his body.
- Graceful Loser: Inverted. He accepts his defeat, saying he was destroyed in the process of doing his duties, and will await for his back-up program to be reactivated. From the onset, sounds like a graceful loss. However, much like his declaration of intent to kill, once you read between the lines, what he's actually saying is that Volnutt's failed even if he's beaten him, he can't stop Eden, to go ahead and kill him because he'll just come back anyway, and leaves on a taunt of his return to active duty.
- Greater-Scope Villain: He only appears near the end of the first game, but his threat level is far higher than that of the Bonnes.
- It's Personal Implied. In discovering an ancient slab, it is revealed to the players that Trigger and Juno fought once for the fate of the island long ago. When Juno reawakens, he's surprised that Trigger was the one who awakened him, subdues him in a lightning trap —which he openly refers to as a trap— and rather than settles things diplomatically, abuses his status as the island's keeper to permissibly to to kill him. His only other story-based appearance following this, in Namco × Capcom seems to solidify this, as he becomes a Stepford Smiler with an ax to grind against Rock for their past upon his return, though he plays up the Affably Evil angle he has here at first.
- Knight of Cerebus: Although he doesn't appear until very late in Legends 1, the game takes a considerably darker turn when he shows up, especially in comparison to the villains the player had been fighting up until now.
- Machine Monotone: His voice is soft, monotonous, and always has a mechanical echo to make it sound all the more robotic and artificial. It becomes lot less monotonous once he goes into his second form.
- Meaningful Name: Named for the Roman god of war, also known as the sovereign and ruler of the state, and daughter of the chief of the gods.
- Non-Action Guy: He does fight you as the final boss, but is still this trope. As a Bureaucratic unit, Juno isn't designed for combat, while Mega Man, as a Purifier unit, is. After you defeat him, Juno admits it was foolish of him to fight you, since it was obvious on paper that he would lose.
- Ominous Pipe Organ: His theme is an arrangement of Bach's "Fugue in G minor, BWV 578" as played on a pipe organ.

- Sesquipedalian Loquaciousness: He speaks with complex sentences and long words, which repeatedly confuses Mega Man.Juno: As keeper of this island, I hereby exercise my Prerogative of Correctional Displacation.
Mega Man: Prerogative of Correctional... What!?
Juno: Allow me to rephrase; I will exercise my authority to terminate your program.
- Villainous Breakdown: When he goes One-Winged Angel, his voice gets deeper and he starts yelling a lot more, and after taking enough damage, he screams "How dare you!?". As soon as he's defeated, though, he's right back to his mild-mannered self.
- You Gotta Have Blue Hair: His hair is a pink-violet color.
A mysterious girl found at Forbidden Island inside stasis who helps the Diggers to uncover the mystery of the Mother Lode, guiding them to find the Keys to find the ancient technology. However, the Mother Lode is not what they think; the Keys Sera is directing them to are needed for her to activate Elysium's Carbon Reinitialization Program, which would wipe out the populace on earth.
- Belligerent Sexual Tension: May or may not have this with Mega Man; Sera's "jealousy" of his relationship with the Master is full of subtext towards both of them, Sera seeming to hate Mega Man as much as she admires him.
- Big Bad: She's the main antagonist of Legends 2.
- The Chessmaster: Manipulated the Carbons and Mega Man to gather the keys to the Mother Lode for her plan.
- Clingy Jealous Girl: She is jealous of Mega Man because the Master showed him affections he never showed her.
- Evil Cannot Comprehend Good: As a robot designed to maintain and oversee the System, she cannot understand why the Master would want to leave its safety, or ask Mega Man to shut it down.

- Unknown Rival: She viciously hates Mega Man, but he has no idea who she is since he has no memories.
- The Unfavorite: All she really wanted was for the Master to smile at her the way he smiled at Trigger, and she could not comprehend why he favored the company of a simple Purifier unit over a Mother unit like herself. The only way she could think of to win his approval was to devote herself fully to her duties. The Master, having realized that the System was wrong, only grew sadder with her intensified devotion, and Sera couldn't understand why.
- Villain Ball: She claims she could have activated the Carbon Reinitialization Program at any time, but chose to wait for Mega Man to reach her so she can destroy him to sort out her issues with him first.
- What Is This Thing You Call "Love"?: Her jealousy for the Master over his friendship with Mega Man, as well as the Master's decision to rebel against the system, confuses her.
- Worthy Opponent: She regards Mega Man as one to her.
- Yandere: Come the end of the game, she's in turmoil over the actions of Mega Man, the Master, and Yuna, unable to understand them or her conflicting emotions towards Mega Man and the Master.

A mysterious woman watching over Sera on the Forbidden Island. She is the Mother unit overseeing Terra, and sealed Sera and Mega Man in stasis years ago.

Jim, Osh and Bensley
- Cassandra Truth: Nobody believed them when they warned the police about the pirates.
- Dirty Kid: They'll really appreciate it if you give them a magazine with naughty cover. This didn't get past the radar for the international release and (Japan-only) PSP port, where it's changed to a comic book. Either way, you're rewarded with X-Buster, one of the needed items for creating Shining Laser.
- Infallible Babble: Alhough they didn't have proof, they were totally right about Tron Bonne being a criminal.
- Treehouse of Fun: They decided to build one after the pirate invasion, which Mega Man can lend a help with a series of Fetch Quest.
- Gentleman and a Scholar: She's kind, and she used to work for Barrell as an assistant before becoming a mayor (although there isn't much moment in the game where her scholarship comes into play).
- Reasonable Authority Figure: She decided to assist Digger's job as soon as she realized Mega Man may solve the potential threat to the people of Kattelox.
- Ultimate Authority Mayor: It appears she's taking charge of everything in the whole island.
PaprikaA dog that belongs to Jim's sister. Jim orders him to chase after Tron Bonne, who's then rescued by Mega Man Volnutt.
- Suddenly Voiced: If you tamed him when he chased after Tron Bonne (though this is the only option in the international version), he'll suddenly talk to you in Playable Epilogue! There's no in-universe explanation for this.
- Video Game Cruelty Potential: If you don't mind it, you can literally Kick the Dog and save Tron Bonne immediately. Only possible in the Japanese version, however.
IraA young girl in the Uptown hospital confined to a wheelchair, unable to walk.
- Ill Girl

Museum CuratorA lady who owns the museum of Uptown. Her dream is making her collection one of the best in the world.
- The Collector: She offers you a sidequest to bring her Ancient Artifact found in ruins. Completing it will grant you one of the needed parts for creating Shining Laser.
- What the Hell, Hero?: Subverted. When she asks you what is missing in her painting, you can be a dick by saying "some talent". She seems to be increasingly offended each time she wants you to confirm what you just said, but even when she eventually gets your point, she just reluctantly agrees with you and shrugs it off. Nevertheless, doing this will lower your Karma Meter.
Art/ArtilleryA young researcher who wants to solve the mysteries of Kattelox Island. He appears around the island over the course of your playthrough.
- Demoted to Extra: He was supposed to be Mega Man's rival, but this idea was dropped during the development. His occasional appearance throughout the whole game is the trace of this original plan.
- Unknown Rival: Downplayed, since his role became very minor in the game, and while he continues his own Digger's work, there's no real tension between him and Mega Man. In fact, he seems to acknowledge his achievement at the ending.
MariaThe owner of the bar in Yosyonke City, living together with her daughter. She found Joe hurt and without memories 10 years before the events of Mega Man Legends 2, and took care of him since.
- Florence Nightingale Effect: She seems to grow affection on him as she's lived with him. After Mega Man obtains the last key, she moved with Joe and her daughter to another island.
ShuA girl living in the Kito Village on Calbania Island. One day, she was kidnapped and held as hostage by Birdbots, but rescued safely thanks to Mega Man.
- Advertised Extra: She was one of the main characters starred in Japan-exclusive demo Rockman DASH 2 - Episode 1: Roll's Critical Moment!. In the main game, her role in the plot is trivial at best, serving as Damsel in Distress in relatively small level.
- Promotion to Parent: She's sibling-parent to Appo and Dah.
- Video Game Caring Potential: After Mega Man's job is done on Calbania Island, you can later revisit Shu and give items like pencils and notebooks to her, who'll then start teaching her brothers how to read and write. Mega Man even receives a letter from them later on.
Appo and DahShu's little twin brothers, they asked Mega Man to save her when he came to the island to destroy Glyde's base.
- The Ditz: They don't look intelligent and often speak with Verbal Tic. Nonetheless, they're not afraid to charge straight to Birdbots' fortress as long as it'd help Mega Man save their sister.
