His gimmick is similar to Turnabout mode from MvC3 but it's a little different. Basically, he can collect evidence using his down special and he has three evidence slots. The slots look like this, on the very bottom left corner above his super meter:
There's a 50% chance that the evidence he grabs will be useless and if so, it'll look dark in his evidence slots. If so, he has to taunt to get rid of it. Up taunt gets rid of the first piece, side taunt gets rid of the second and down taunt gets rid of the third. The more evidence he has the stronger his attacks will be and some moves will change depending on how much evidence he has. After around 15 seconds, one piece the evidence he has will disappear and he'll have to use his down special again to get it back. However, if he has three pieces of evidence they'll all disappear at once instead of just one piece after the 15 seconds. The evidence resets after a KO.
Neutral Special: Take That!/Objection!
In normal mode, he will point a finger forward and a large speech bubble that says "Take That!" will appear. If he has three pieces of legitimate evidence, the bubble will say "Objection!" and it will be much larger and do more damage. BTW, if Kirby copies him Kirby will just have the objection bubble
Side Special: Steel Samurai Maya Smelting
Maya Fey appears and runs forward, doing a barrage of punches. If done in the air, she will fall and do the barrage while falling.
Up Special: Jump
Pretty much his up special from Smash Crusade without the "hold it" bubb;e
Down Special: Investigate
Starts searching the ground and adds either a piece of legitimate or illegitimate evidence to his evidence slots
Final Smash: Cornered
Literally just his final smash from Crusade only with a few differences:
- Obviously in HD to match the visual style of this game
- The part of his speech where he says "no alibi, no justice, no dream, no hope" is taken out and so he just says "the one who actually committed the crime is you, it's time to pay for your crimes, take this"
- It's an objection bubble that initiates the cinematic
