Krookodile is a Pokeball Pokemon canidate for SSB4. He uses Fire Fang, Ice Fang, or THunder Fang. Anyone who gets caught in this attack's path is guaranteed to get burned, frozen, or shocked. The attack bypasses shields, and can easily hit even giants and metallic players. It can't hit those who are impervious to flinching (such as Wario-Man), however. If the attack doesn't KO, it'll still send targets flying a great distance.
Also, there is a bit of a delay before Krookodile executes his attack, giving opposing players a chance to flee before… POP! BOOM! BANG! He strikes.
