Synopsis:
While in town getting supplies, the Challengers meet five men drawn from the past. After fighting them and bringing them to Challenger Mountain, the Challs are attacked by an alien beast called Monstus. They are captured themselves by Monstus’s master, J’Kal who has brought the men through time for a zoo. He also intends to take one of the Challengers.

Before the alien can act, the Challs escape. While Prof and June escape, the others distract Monstus. They are almost defeated, but an alien lawman arrives to take J’Kal into custody for his actions. J’Kal pulls a weapon, but a distraction allows Ace to jump him. The lawmen returns the men to their rightful time periods and leaves with J’Kal and Monstus.
