Gone Fission Blitzcrank

a comedic skin for Blitzcrank (like he didn't have enough already).

Blitzcrank's splash art would be him wading out into the water with a fishing pole, with hundreds of dead fish popping up to the surface due to his radioactivity.

He would be wearing a fishing hat and vest, and would have a fishing pole slung over his shoulder.

His model would show him to be nuclear powered, complete with little nuclear warning icons.

When his ultimate comes up, he glows green to show his radiation.

When he recalls back to base, he would throw his fishing line out, catch a giant radioactive fish (or maybe a manatee?) and get carried off back to the fountain.

Alternatively, if you hate puns, you could throw out the whole fission part and just make it a fishing skin. Because Blitzcrank going fishing is already pretty funny.
