In Mega Man X6, Wolfloids appear in Blizzard Wolfang's stage. They were infected by the Nightmare Virus and attack the player by either launching bombs or by breathing ice. There are also some Wolfloids that haven't been infected yet and ask for help.
In Mega Man X: Command Mission, these robots are blue ice-based versions of the Wild Dogs. They occasionally get angry when an ally is defeated before its turn, concentrating all Allies' Attacks (using Standard Strike or Smash) on the target (party member) with the lowest LE. They appear in the Melda Ore Plant and in one section of Gaudile Laboratory's Eternal Forest. A Wolfloid can be used in the Deployment Center.
