Assist Trophies and Pokemon

[-Sooty-]

I'm not sure If we can still suggest ideas but for a Pokemon you could have ditto who takes the form of a random 'Playable' Character who is on the screen and attacks the closest opponent, if there is a Smash Ball on the stage at the time of it being released from the Pokeball then it will act as a second smash ball which is identical but if the Ditto one is activated then it will blow up with a Large Knockback... probably the same force as if the opponent would destroy a bob-omb
