Cho'Gath skin concept

So, here's an idea for an ultimate Cho'Gath skin: Cho'Gath, Devourer of Worlds. Seeing as we couldn't let it overlap with Dark Star, I was thinking perhaps designing it with more of a Cthulhu vibe(though I would like to hear other designs which may fit with the skin's name). Since the eldritch colors are generally green or purple, the skin would most likely be dominantly green in coloration since the base skin is purple. It'd also have to not rely too much on tentacles in design to avoid overlapping with Illaoi. So, ideas for the abilities' visuals: Q: Bizarrely shaped spikes(perhaps something else which could serve a similar purpose) which change in appearance based upon the ground on which the ability is cast shoot up from the ground and then float in the air for a bit after the ability is used. W: The tentacles on Cho'Gath's mouth spin, causing waves of green energy to shoot towards it in a cone. E: For the next three autoattacks, the air behind the target ripples, that being the equivalent of the projectile shot by base Cho'Gath's E. R: Cho'Gath's mouth tentacles spread out and then grab the target, devouring them. Obviously it'd need to have it's appearance altered as it got larger, but I have yet to come up with any ideas as to how exactly it would change. Other animations: Joke: Cho'Gath stomps the ground, causing a piece of ground shaped like a skull to pop up out of it, at which point Cho'Gath catches it and poses à la Shakespeare. Taunt: The air behind Cho'Gath ripples violently and then ruptures, revealing an alien landscape filled with incomprehensible shapes(A quote I thought of for the taunt is "You cannot comprehend the horrors that lie beyond your reality."). Dance: Cho'gath twirls and hops, destroying and reassembling it's body as he goes(for example, having it's torso detached from it's limbs and falling through a portal, only to fall back into our reality soon after). Laugh: Cho'Gath emits strange noises whilst whipping the tentacles on it's mouth. Recall: Cho'Gath conjures a small sphere on the ground which begins to suck it and the surrounding ground in, stretching it and pulling it in via vortex before spitting it out at the base. I haven't really though of any voicelines for the skin, but I'd like to hear all of your ideas for anything regarding the skin!
