Calavera

Calavera (Spanish for "skull") is the midboss of Spooky Trails in Mario + Rabbids Kingdom Battle. As suggests, he is an undead Rabbid with  attire. He also had Rabbid Yoshi in his grasp.

Calavera's main attack involves him shooting bombs at characters which destroy any Giant Brick Blocks caught in the blast. He can also lure characters away from him by "screaming". When defeated, he falls into a nearby well, and Rabbid Yoshi shoots him repeatedly.

Trivia

 * If Calavera is fought with Rabbid Yoshi on the player's team, a normal Rabbid will replace him.
