Trivia[]

  • The boss's model resembles some characters in other game, especially Resident Evil series.
  • This is the third Z-Virus mutant that is able to gain consciousness after Dr. Rex and Laser Wing.
  • When the boss is doing rocket and minigun attacks, he is invulnerable to any damage. This is probably to avoid possible bug where the boss is dead while he's in unreachable area.
    • However, there is a bug where if a player uses Bendita to shoot Jack when he is using rocket or minigun, he/she still can damage him.
    • There is another bug where sometimes when Jack jumps on to the high place of the boss room, he will be stuck (cannot jump down), which makes him "invulnerable".
    • Nevertheless, some previous bosses also have "vulnerable time" but they are not flashed with white cover.
  • Some skills of the boss may be an inspiration from Goku's skill from Dragon Ball series, most noted with the Instant Transmission and Kame Hame Ha skills.
