Arcade Rengar, basically Keyboard Cat Rengar (complete with keyboard instead of knife)

His Passive would have a Mario jumping sound effect.

His Q would be him smashing his keyboard on his enemies (flying keys for extra effect)

His W would be him making an exclamation point above his head in a similar manner NPC's in RPG's do when you talk to them.

His E would be him throwing a bunch of cables (for his keyboard).

And finally while stealthed in R, the hearts above his enemies' heads would be pixelated.
