Tron Bonne is the semi-arrogant mechanical genius middle child of the Bonne family of air pirates. She’s a 14 year old who first appeared in the Megaman Legends series, and proved popular enough to get her own game, The Misadventures of Tron Bonne. She has a crush on Megaman, her semi-enemy. According to Seth, she’s “the least evil of the Capcom villains”.
Within the game context, she uses her Gustaff (the robot vehicle she travels in) and is helped by her forty SERVant roBOTs (Servbots, aka the little Lego dudes). The special servbot with the red hat is her favorite, and is slightly more powerful and more independent.
Note that the Japanese name for Servbot for Kobun, which generally means underling, henchmen, or child (versus the oyabun, who is the leader or parent).
MvC2 Notes
[details=Spoiler]Tron is most widely known in MvC2 for having a weirdly powerful assist - her normal 15pt damage three hit cMK (5,5,5) does 45pts (15,15,15) as her projectile assist type (Y).
Her gameplay is generally weird, but she is incredibly good with her corner throw combos/resets. Her moves generally are great, but prone to being very laggy if whiffed. Her jumping fierce punch in particular is outstanding with excellent crossup potential.
Her air dash gives her a touch of extra mobility and lets her do interesting rectangle jump rushdown.
Her drill can do a stunning amount of chip damage, can generally be tiger-knee’d for extra usefulness, and is great for moving around the screen.
She has a straight-forward infinite using the Kobun Capture gun and the Beacon Bomb, but generally the hitbox on those is small enough that you can’t use those safely on anyone not either in block stun or a little ways away. Still, the Capture gun is an invisible projectile, which can make for some small shenanigans.
Her Lunch Rush super does linear nonscaled damage (1 dmg per Servbot) and so is a prime goal. Missing this gets you killed, and the DHC window is very small. There are only 40 Servbots: if you look closely you will see that one of the last people in the lunch line is Data the monkey.
King Kobun is a little harder to set up, but could be used to **semi-**safely cover a blocked drill. Notably it has one hit of super armor if Kobun is allowed to grow to giant size.[/details]

Air dash
Specials
Servbot Launcher/Capture Gun: :qcf:+:atk:
–> Much faster than in MvC2. Note that the Servbots retrieve a Zenny (money), not life. This does not help you if you wait for it. Kill 'em.
Beacon Bomb: :dp:+:atk:
Bonne Strike (air): :rdp:+:atk: Mash for more hits.
Bonne Mixer (command grab): :hcb: +:atk:
Supers
Servbot Takeout/Lunch Rush: :qcf:+:atk::atk:
–> Nerfed but now hits [media=youtube]uyKkcjsA0vU&feature=player_detailpage#t=107s[/media]). Can combo into from King Kobun.
Servbot Surprise/King Kobun: :dp:+:atk::atk:
–> Startup is now much slower, but it comes with more superarmor and seems to combo readily off of :c: in the corner.
Bonne Slam (3 levels): :hcb:+:atk::atk:
–> Instant throw. Can cancel blocked Bonne Strikes with this.

Combos

I don’t know people who have played Tron yet. Report in! Supposedly you can combo pretty much anything after the drill now. In the videos so far they seem to do the following combos. Note that this is guesswork based upon what was shown.
