Whitstache

Whitestache is a 5-star ground unit based on Whitebeard that starts as a single-target attacker and eventually becomes full AoE, making him more useful for clearing grouped enemies than for focused boss damage. He costs 450 to place, has only three upgrades, and ends at 11,130 total cost, so he is a mid-investment option rather than a cheap early carry or an expensive late-game finisher.
