Okay time to the good stuff. I'll break it down into sections. It will normals, special moves, movement, and supers.
Ratchet and Clank
Normals
Very quick and strong normals. He has combos for days, so expect him to have a lot of meter.
Sepcial moves
It's been a while, but I only remember one of the weapons. It was the Ryno 2.( which is his super) But his Aircannon game, burp gun, and what i think is one of the sniper rifles have their uses. The air cannon can suck someone in and Ratchet can fire them anywhere he wants to in the area. I bet it's a short time though. I mean in the game you cloud suck something in and keep in there forever. This might lead to different ways to kill than we thought. They also help him with a lot of his combos.
Movement
If he uses the heilcopter and his charge boots. He will be hard to catch. He will be up there with Sly for some of the movement in the game. His movement is good.
Supers
lvl 1- the return of the ryno baby! Looks like it can be combo into, and if it works like ti does in the game it will hit anyone in its range of fire because it locks on every enemy in its sights.
lvl 2: Clank joins the fun and uses his time staff to slow down everyone to get kills. They take up a decent amount of the screen, so this super is stage depend.
lvl 3: waste of meter and time just like Sly's level 3.
Best super for ratchet is lvl 1 actually.
Spike(Kakeru)
Normals
It seems his stun club and a bigger stun club will be his normals. They are fast and I see lots of combos.
Special moves
lol every gadgets in AE games is here. Even the ones from AE 3...lots of madness going on. I cant' explain it.
Movement
Not bad, but I hope he has that flyer gadget as a way to get around. He'll be 3rd best if he has that.
Supers
lvl 1: I hope he can combo into the net, because the range on the net is ass. It will be worthless if he can't do that.
lvl 2: Great way to pick someone off, but easy to dodge, so be careful.
lvl 3: if you got it, I'll let it fly since it's going to kill.
I'll do the other two later.
