Huh. Well, let's keep throwing movesets out there. Even though I don't particularly like K. Rool, the more I read the thread and think about him the more I like the idea of him being in Brawl, and the more I can actually imagine it.
K. Rool, while he seems fairly generic, does have a fair amount of personality... i.e., he's pretty much the biggest nut job that Nintendo's ever had. And I think his attacks would have to reflect that complete insanity-- Instead of just swinging his limbs, he should do everything fairly exaggerated, such as reaching far back and thrashing forward wildly instead of an efficient looking slash like Bowser. His running attack would be him shaking around with his arms in front him while yowling in mad fury. Yes yes... I can see him adding a bit of insanity to Brawl.
Another thing that could make him unique is being able to switch costumes with one of his B moves, which would then center the rest of his B moves around that outfit's properties (but then keep all the A moves the same as normal because that's just easier). It wouldn't really be like Zelda/Shiek, since basically it just adds a bunch of moves and it's still basically him. Just him with multiple personalities.
B down, Quick Change: After pushing down B, you can indicate which personality he would take on using the control stick and letting go of B. Left, Boxer/Wrestler. Right, Scientist. Up, Buccaneer. Down/Neutral, Default King. Then, he disappears in a brief puff of smoke and when it clears he'll be wearing whatever outfit was indicated. If interrupted, he stays as whatever he was before.
So, each costume would have 3 special moves.
Boxer Krusha K. Rool, the melee oriented personality:
B^, Kroc Krash: He launches himself upward at an angle in belly flopping position, and lands with tremendous force. If it hits people while he's jumping up, it lightly knocks them out of the way. On the way down, it slams them downward with some damage, and if he actually squishes an enemy between the ground and himself, then larger damage occurs (but they just get knocked to the ground, no KO capability just stun and damage).
B>, Champ Charge: A chargeable dashing attack. The longer, the faster, stronger, and further he jumps forward and uppercuts an enemy.
B, Counter Blow: Puts up his gloves for defense against things in front of him. If he gets hit, he can then indicate up, down, or forward and knock the attacker in that direction with an uppercut, headbutt, or just slug them forward.
Scientist Baron K. Roolenstein, the mad scientist with odd moves:
B^, Jetpack: Shoots him fairly far upward with some randomization. He dons the jetpack which, instead of flowing normally, gives off a large explosion propelling him upward. It's not very controlled, but it deals significant damage to those below and sends them in a direction outward from the explosion's center.
EDIT: Or, alternately, an up B move involving his propeller which would work... well, similarly to however it did in the game.
B, Potion: Throws a beaker full of odd colored liquid. It arcs up at an angle and then falls down. Exactly what happens corresponds to the liquid's color, this'd be where all the control reversals and such could be, as well as just plain damaging attacks.
B>, Spray: takes out something that looks like a fire extinguisher, more or less and sprays. This too is randomized and can effect multiple people nearby and in front of KR. However, all of the effects are strictly offensive- one can poison the enemy to make them take damage over time, another can freeze them, another can spray out rocks that do damage etc.
Pirate Kaptain K. Rool, the projectile persona:
B^, Rocketteer: He uses his gun as a rocket and shoots up at an angle. Those in the way get smaller damage and knocked away (ala Mario's attack). Also, the gun can shoot out a cannonball that goes the opposite direction, making it a sneakier attack as well.
B, Vacuum: The musket sucks in air. Everything, even items and projectiles, get pulled into the gun. However, it can only hold one thing so the first thing to get sucked in stops the vacuum attack. Players that get sucked in (they can roll away out of range if they're fast) also get sucked into the gun, but they can escape by moving a lot, resulting in the gun exploding so he has to laggily pull out another musket.
B when it has something in it: KR shoots out the object, basically as if they were throwing it like a normal item. This includes enemies projectiles however- so KR could absorb Samus' charge shot and then throw it back at her.
B>, Boomstick: Launches a cannonball. It's very slow, possibly the slowest projectile out there, but it does a lot of damage on a directed hit. Less than Samus' charge shot, but a lot considering there's no huge charge time necessary. If the cannonball is attacked, though, it drops and then can be used as a normal item (until it disappears after a few seconds). Very slow move, but worth it for stopping recovery.
In the air, it will knock KR backwards, so skilled players could use it for a little extra boost for recovery.
King Rool, the default persona:
B^, Super King:Simply shoots up at an angle, with one hand forward and cape flapping in the wind, trying to look like a superhero. More or less like Marth's, except at a sharper angle.
Boring, I know. I'm losing my movelisting steam here.
B, Kremlin: Tosses those generic Kremlin badguys that walk on all four. These will continually walk along the ground until they fall off a cliff or are killed by an enemy's attacks. Slower than the Ice Climber's ice blocks, but they would go through enemies and last longer. Good move to spam, though easily countered if the enemies just kill them.
B>, Crown Toss: Tosses the spinning crown forward, and after going out a bit, it homes back onto KR to come back. Unlike Link's boomerang, if KR avoids catching it again it will loop back and try to get him. If you continually avoid catching it, the spinning crown will stick around while still damaging enemies until caught.
And remember, every persona's down B would be the changing.
Comments? Long read, I know, at least just comment on the idea of him assuming the different personalities.
