Party Brainz

Party Brainz is a Legendary variant of Super Brainz in Plants vs. Zombies: Garden Warfare 2. Party Brainz has a meter that passively fills up by gaining Vanquishes. When the bar is filled up, Party Time! activates, giving him a temporary damage boost and also allows him to moves faster and punches faster. The player cannot unlock Party Brainz using sticker packs. Instead, he/she has to get him from collecting Time Shards in Infinity Time.

In-Game description
"It's the Neon Icon himself! The one and only Party Brainz. He's been partying so long and so hard, that he can't remember what mission Dr. Zomboss sent him on in the first place."

Party Time!
Party Time is Super Brainz' variant ability. Above the ability HUD, the player can see a bar for Party Time. By getting Vanquishes, this bar will slowly fill up until it's full. When the bar fills up, Party Time will activate, giving Super Brainz a temporary damage, attack speed and speed boost for a short time.

Trivia

 * When the Party Time! ability is activated, the Pop Jam starts to play.
 * Similar to many other Legendary variants, Party Brainz is eighties-themed.
 * Despite looking identical to the Sweatless Band, his Party Hair prevents accessorys from showing.
