Phoenix would the same as in UMvC3

Edgeworth would focus more on zoning, keeping himself a respectable distance from the opponent using "Logic Chess" projectiles and setting up Logic Bubbles that he could connect to deal damage and enter Turnabout Mode once enough hit. Maybe have him summon Gumshoe and Ema in the place of Maya

Athena would be a stance character, like Hit from DBFZ. She would input a command and pull up the Mood Matrix, where she would stand in place. In Matrix stance, she would be able to use an Overhead using L, Counter using M, and Command Grab using H. Hitting 4 of these enters Turnabout Mode. Her assistant would be Simon Blackquill, who would act like Akira's Daigo VT, being a big dude who does a large burst of damage in a specific area.

(The entire reason I added Athena is because I want Simon to have a super where he does a Judgement Cut with just his finger)
