Xero

Xero is a 5-star Purple Ground unit built around team support rather than raw damage, so his value in tier discussions depends heavily on how well a lineup can take advantage of his buffing. His signature ability, Xero Requiem, boosts other units in range by up to 40%, or up to 50% when the buffed unit matches Xero’s element, making him especially strong in coordinated setups that can rotate multiple Xeros to keep the bonus active.
