PaRappa: Circle (they can jump out but they have to actually jump imediately afterwards, basically they have to know youre going to do it)
Fat Princess: Aerial Forward Circle
Sweet Tooth: Aerial Square
Sly Cooper: Circle (stage obstructions sometimes interfere with this)
Nathan Drake: ???
Ratchet: Forward throw, use level 1 super close to them before they recover while theyre doing a recovery roll so they will get hit no matter which direction they roll
Big Daddy: Forward Circle
Dante: ??? (some wickedly hard to do combo, please post something quicker and usable in 4 player matches)
Raiden: Forward Square
Sackboy: Up Throw (only works on Big Daddy and very selective characters), otherwise Down Circle
Sir Dan: Bow + Arrow (not sure which command this is)
Spike: Aerial Forward Square
Please add to the list if you can fill in any of the "???" with a move that sets up a level 1. please dont post stuff that does not work. and no need to list multiple for one character, like yes im aware heihachi's lvl1 can be set up with down square, but his counter is way more reliable so i listed their best stuff.
Well so far I got it to work on Radec, Heihachi, Sly, Toro, Spike, Big Daddy, FP, Kratos, Parappa, and another Sackboy. But that's because those are the only character my friend was using... I don't see how it wouldn't work on anyone else.
