Mario is the leader of the Heroes in Mario + Rabbids Kingdom Battle, unlocked at the very start of the game. He is required to be used in every single battle of the game, including challenges. He is a non-Rabbid Hero.
Mario has a red shirt and hat, as well as blue overalls fastened with yellow buttons. He has brown shoes. His hat has a red and white "M" logo on it. His facial features include a large nose, large eyebrows, a mustache, and light blue eyes. The only part of his appearance that is unique to Mario + Rabbids Kingdom Battle is the blaster that he wears on his right arm.
Mario's Stomp Jump is a movement ability unique to Mario. When Mario Team Jumps with this ability unlocked, he may stomp on an enemy's head and land 3–6 blocks away (depending on upgrades unlocked on the Skill Tree). This typically does more damage than a dash, as his dash does 20, 40, 60, 90, or 130 damage, but his Stomp Jump does 30, 50, 70, 100, or 150 damage (both depending on upgrades).
The Cleansing Jump allows Mario to clear Super Effects from other Heroes when he Team Jumps off of them. This works with any lingering Super Effect. This ability is not unique to Mario; every Hero has it.
- Mario is the only Hero to have the ability to upgrade the amount of heath restored from a Mushroom, which is most likely because the player cannot take him out of the team in between battles, unlike other Heroes.
