Evil Mew was bored and fused together a Kangiskhan and a Slaking. This is what happened.

Slakgiskhan has the ability parental bond and is not lazy and really strong, he also has a Slakoth child that can raise the dead if he needs to.

Slakgiskhan can't mega evolve but makes up for it by having a new attack called Bongos and Shit. This attack has Slakgiskhan play bongos so badly that anyone that hears it implodes.

The sun also works for him and will do whatever he says including explode so he can end the world if he needs to.

Finally his weakness that will automatically kill him is cucumbers, they just kill him.
