Bwaluigi is a notable enemy in Mario + Rabbids Kingdom Battle. As his name suggests, he is similar to Waluigi, with similar height, cap, and clothes, although he is bulky rather than skinny. His artwork incorrectly depicts him with bright blue overalls; however, in the game itself he wears the proper blackish blue-colored overalls.
Bwaluigi appears in the Lava Pit, apparently summoned by the Megabug to stop the heroes' advance on Bowser's Castle. He is fought twice (outside challenges); the first time alongside his weaker ally Bwario, and the second time alongside both Bwario and the Lava Queen.
Bwaluigi behaves much like a Smasher; charging at the heroes (both on his turn and after being attacked with ranged weapons) in an attempt to hit them with the large red pipe he uses as a bludgeon. This can also inflict the Honey status on a critical, leading to heroes being stuck next to him, allowing him to hit them multiple times. In addition to significantly more HP than most enemies (and even some bosses), he can force characters towards him (similar to Rabbid Mario's Magnet Dance), possibly making them vulnerable to attack (even more vulnerable if Bwario's Villain Sight is active and he's near Bwaluigi). He and all of his allies must be defeated to claim victory.
