Shield
Shield costs 2 Charges to use, confirmed directly from its in-game move reference card, which also states its effect in full: it always moves first, and it blocks 1 move from the opponent.
It's the rarest kind of slot in the documented movepool - a true defensive option in a game otherwise dominated by damage abilities. Brainrots that carry Shield stand out from their same-rarity peers precisely because most kits skip a defensive slot entirely.

Team-building tip from community discussion
Community discussion during the launch window recommends running 2-3 Shield-carrying brainrots on a team rather than just one, so Shield's "always moves first" property can reliably intercept a big hit - the same discussion cited a level 50-55 Firework use hitting for roughly 400-500 damage as the kind of hit worth blocking.
