So lets go over a little backstory.
Heavy Rain is the spiritual successor to Indigo Prophecy, a quicktime heavy game for the PS2 about unnatural circumstances that ultimately played like dog piddle but had a sense of urgency with a lot of its core mechanics. It had a LOT of quicktime events and, at least for the time, a new and interesting way to get a point across.
Fast forward a few years to Heavy Rain, a murder mystery concering the likes of four random people in the city who get involved with it. The main character, Ethan Mars, having lost JAAAASOOON to a car accident a year prior, has his other son kidnapped and goes through literal hell to reclaim him. While it was particularly bland, especially the hour long 'happiness' hour tutorial, the rest of the game was at least above par.
Next year is another game by the same developer with the same mechanics; Jodie Holmes, a teenage girl who is spiritually latched onto a ghost. This ghost fights for her, by taking over other peoples bodies and using them to help her survive.
From my point of view, Jodie is a lot better than Ethan Mars for getting into Playstation All-Stars. I keep hearing Ethans name brought up so lets get this out of the way: Ethan does not belong in a fighting game. If he gets in, and his Level 3 isn't 'JAAAASON', I'll personally push a kid in front of a car. Not really. Anyways, Jodie's a lot 'more'. While its fairly obvious she won't control other people, what she 'could' do is the Fat Princess approach with more on an emphasis on zoning tactics than fistfighting. She could summon SWAT team members (the ghost takes over them in certain parts and shoots other SWAT members) who come up and fire off rocket launchers, sniper rifles, or various other weapons. What could be interesting is if you could leave Jodie on the side and have your SWAT member summoned to fight for you, and if that takes enough damage you go back to being Jodie, trying to escape attacks while setting up for another SWAT member. (If she's hit the member automatically dies, etcetra.)
Not only because of comedic effect, but because he could have a crazy moveset.
The electric wires from the butterfly test, the sword scott shelby used to kill somebody with, Norman's AFI glasses spawning tanks, items he could have used to cut off his finger with, orgami figures.
