Rovio presents... Angry Ziggs!
Humor me and pretend legal issues aren't a problem.
Why's he angry? Because of those freaking pigs!
That's right, I'm suggesting a skin for Ziggs based off Angry Birds.
For Ziggs himself, I'd have him parodying this particular pig, disguised as one of the Blues. For the skills, see below:
P - Ziggs throws the Yellow Bird (Chuck) when using Short Fuse.
Q - Ziggs throws the Red Bird when using Bouncing Bomb.
W - A Black Bird is used as Satchel Charge.
E - Ziggs deploys a cluster of the Blues as Hexplosive Minefield. (Yeah, there's only supposed to be three Blues, but for the sake of this skin, pretend there are more.)
R - Ziggs calls in the Mighty Eagle when using Mega Inferno Bomb. The target marker is a tin of sardines.
When recalling, Ziggs pulls a giant slingshot out of Hammerspace (basically, out of nowhere) and launches himself in the direction of his team's base (the actual launch occurs at the end of the recall).
Fits him perfectly.
