3 skin concepts, (Garen, Nami, and Zac)
Garenteed Satisfaction Machine A "viktorius" skin where Garen is rebuilt into machine. He has a light saber, because light sabers rule. Garens legs become wheels when he Q's. Instead of saying Demacia he yells Domination
Surfer Nami Surfer singed theme nami skin where her trident becomes a surfboard. She wears a baseball hat and sunglasses like a surfer bro. I'd like to say nami should be able to ride her own ult, as she says "ride the waves" but apparently that would be too op, even if she was blocked by terrain.
Jello PAC Zac
His passive blobs are jello rings, his passive is jello rings. He's rainbow jello, so to be different. His ult turns him into a cube of jello or maybe a jello pack.
