Depends on if Heroes Trunks is included, because if so it's a tossup between the Drink Army and Piccolo.

In that case, they'd all need a cup to carry them to victory, or maybe one big cup they can all fit in. This could be a great time for Piccolo to make an ally out of his enemies by serving as this "big cup" for the drinks
