Blue Trooper is an enemy that appears in Bomberman 64. They are combatants of Altair who appear in the first five worlds, wielding a blade in each hand. They move slowly and aimlessly, occasionally pausing to look around. They will stun Bomberman on collision. If a Blue Trooper catches Bomberman within his field of vision, he will begin to swing his blades and chase Bomberman, harming him on contact. Eventually, he will stop and return to his normal movement pattern if Bomberman manages to escape. Blue Trooper takes one bomb blast to defeat, and a single Pumped Bomb thrown on top of him will defeat him as well.
In Hard Mode, Blue Troopers move more quickly and take two bomb blasts to destroy.
