Special Traits / Other:
King K. Rool’s second jump summons his helicopter backpack that can allow him to hover the same way that Peach can. (Dr. K. Rool—3:50)
One of K. Rool’s taunts can cloak himself (similar to the cloaking device in melee) for a few seconds.) (Kaptain K. Rool—2:35)
Another one of K. Rool’s taunts would be falling over and pretending he’s beaten and getting back up. (King K. Rool—1:35/2:03 and Kaptain K. Rool—2:05)
Weak Attacks:
A Combo
Donkey Kong’s A Combo is probably fine here.
Forward Tilt — Remote Shock (Dr. K. Rool 2—1:43)
K. Rool uses his remote control to cause electricity to travel along the ground in front of him. Pikachu’s Neutral B (Thundershock) would probably be a good effect for this. If Pikachu’s Down B Thunder could somehow be recolored, made slower and weaker, and moved horizontal, this would be best but that’s probably too much to ask for.
Up Tilt
K. Rool could thrust his gun upward and hit his opponent with the back end of it.
Down Tilt
King Dedede’s ducking animation and Down Tilt could be fine here.
Running A (Kaptain K. Rool—0:24)
K. Rool propels himself forward, using his blunderbuss as a rocket, and charges at his opponent.
Smash Attacks:
Forward Smash – Vacuum Blast (Kaptain K. Rool—2:25 and 3:11)
As K. Rool is charging this move, he can pull his opponent towards him with his Blunderbuss. Once he releases the move, he releases an elemental blast (probably using Toon Link’s bomb explosion) which can randomly freeze his opponent or reverse their controls for a couple of seconds.
Up Smash — Copter Pack (Dr. K. Rool—3:50)
K. Rool jumps upward shortly and attacks his opponent with the blades of his helicopter backpack.
Down Smash — Needle Canon Ball (Kaptain K. Rool—0:43)
King K Rool shoots an Unira (Spike ball item) out of his blunderbuss, which sticks into the ground. If K. Rool uses this move and there are already two of these out, the first one will disappear.
Specials:
Neutral B – Blunderbuss (Kaptain K. Rool—1:06, 1:15, 1:26, and 1:47)
K. Rool shoots a cannon ball out of his blunderbuss that can act in one of three ways at random. The shot can travel straight forward, bounce along the ground, and move forward in a spiral. If possible, K. Rool could rarely shoot out a barrel instead of a cannon ball.
Forward B – Crown Boomerang (King K. Rool—0:08)
This is pretty much exactly Toon Link’s boomerang, only using his crown.
Up B – Ground Pound (King K. Rool—2:14 and Krusha K. Rool—1:59)
This can be King Dedede’s Up B pretty much exactly. One thing that could be cool is if he could cause some weak shockwaves to travel along the ground after he lands.
Down B – Aerial Cannon Ball (King K. Rool—0:43)
This would work a lot like Pikachu’s Thunder, except K. Rool summons a large cannon ball that falls from the sky. Unlike Pikachu’s Thunder, the cannon would fall just in front of him instead of directly above him.
Grabs:
Forward Throw
Donkey Kong’s Forward Throw could be cool here.
Back Throw
Donkey Kong’s Back Throw is probably best here.
Up Throw
K. Rool could toss his opponent onto his copter pack and attack him with its spinning blades.
Down Throw
Bowser’s Down Throw is probably best here.
Aerial Attacks:
Neutral A
King Dedede’s Aerial Neutral A looks fine here.
Forward A
Donkey Kong’s Aerial Forward A could work here.
Back A
King Dedede’s Aerial Back A could work here.
Up A
Bowser’s Aerial Up A could work best here.
Down A
Donkey Kong’s Aerial Down A is probably fine.
Final Smash
This could be really similar to Dedede’s Final Smash, except he can summon different kinds of Donkey Kong Country enemies (like Kritter, Klap Trap, Zinger, etc…)
