Bwario is a notable Rabbid enemy in Mario + Rabbids Kingdom Battle. As his name suggests, he is similar to Wario, with his signature mustache, cap with an upside down logo of Mario's "M" rather rather than Wario's unique "W" logo and not overlapping the white background along with lacking the white stripe around the brim, and clothes; unlike Wario, however, he is quite small and not obese. His name is a portmanteau of "BWAH!" (a sound that Rabbids make) and Wario.
Bwario appears in the Lava Pit, summoned by the Megabug to stop the heroes from reaching Bowser's Castle. He is fought twice in the game (not counting Challenge levels); the first time alongside his stronger ally Bwaluigi, and the second time alongside both Bwaluigi and the Lava Queen.
Bwario behaves similarly to a Valkyrie. He has significantly less HP than Bwaluigi, but attacks at range with a gatling gun seemingly built out of green pipes. He can also activate a "line of sight" technique to hit heroes as they move. His team jumps also produce close-range shockwaves upon landing, seemingly by smashing the ground with his gun. He and all of his allies must be defeated in order to claim victory.
