|First Appearance:|| It's Walky! 29 July 2001|
|Squadron(s):|| Squadron 37|
| Spoiler warning!|
Plot and/or ending details follow.
A member of Squadron 37, he and the rest of his team were sent to the Bermuda Triangle to investigate the Martian Embassy, where they were ambushed by the Head Alien and Monkey Master. Chasing after Monkey Master, Zack was caught and cut and half by the Tarantuguns guarding the Embassy.
He was fondly remembered by his remaining teammates.
- It was once implied that Hooper may have disinterred his corpse and eaten his remains.
- Like many members of Squad 37, Zack was based on a real-life acquaintance of David Willis. This means he's unlikely to make a reappearance in the Dumbiverse.
