I reckon that he "grows" with level. Or possible kills. Or CS. Maybe similar to Thresh, except instead of stats he gets bigger. Maybe like Rengar's Bonetooth Necklace, he gets new effects when he reaches certain stages of growth.

So: Rampant Growth (I know the names taken)
 * "ZAC grows over the course of the game. Every time he levels up or scores a kill (assists count), ZAC gains a Growth stack. At 5 stacks, ZAC gains X; 10 stacks, ZAC gains Y; etc."
