Raid Boss Mundo (Skin Idea)
I need more Mundo skins and I really like the Boss skins such as Battle Boss Blitzcrank and Final Boss Veigar; even though I don't play those champions, I still got those skins for ARAM.
I'd think it would just be grand if Mundo was part of the Boss line-up, giving him video game qualities to his spells and animations, which I think would compliment Mundo's kit quite well. Why Raid Boss? Mundo is pretty hard to kill unless tackled in a coordinated manner and he can deal quite a bit of damage in the right scenario.
