- "Ya-hooo! There goes another one!"
- ―Jack McHammer
Jack's Sand Blue legs are printed to resemble jeans with knee-pads, pockets, and belt printing on the hip. He has a printed plaid green shirt and a leather jacket. He has one green arm with a yellow hand, and one mechanical arm, similar to the one used by Dr. Inferno and the Alien Cyborg. His yellow face is printed with dark orange eyebrows, mustache and beard, and has a growling expression. He wears a flat hat, and carries a large hammer.
Jack McHammer is one of the Monster Fighters. The Crazy Scientist was the one who removed Jack's arm, which was then replaced with a mechanical one. Ever since, the Scientist and his Monster have become Jack's formidable opponents.
- His monster arch enemy is stated to be The Crazy Scientist's Monster, and preliminarily his was in 9466 The Crazy Scientist and His Monster, but since the Monster Fighter has been changed to Major Quinton Steele; therefore, Jack McHammer does not actually face his monster arch enemy.
- His head printing is similar to the Crown King or Bandit.
- His name is a pun on the tool "Jackhammer".
- Jack McHammer reuses the hammer piece, first made for Thor, from Marvel Super Heroes.
