A Zolera beast is a magical creature with the power to sap the magical energy of any magical being or creature. It uses tentacles to reach out, grab ahold of and then suck energy away.
It's only appearance is in A Helping H.A.M.
The Zolera beast in the show is first introduced by H.A.M. leader "Lex" to Monroe as a creature that would help win their fight against magic in their first wave of attack. As they had been unsuccessful in training the beast to do anything, they had kidnapped and recruited Monroe to do the training instead. When Juniper arrives to rescue Monroe, the beast is accidentally released and starts attacking everyone. It manages to zap Juniper as the only magical being nearby of large portions of her magic.
However, at the end of the episode it is revealed that Monroe did in fact train it, but to obey only him. Monroe commands the creature to stop, lay down, and then tells "Geoffrey" to give Juniper's magic back.
- Monroe names the Zolera beast in the show "Geoffrey" (pronounced like "Jeffrey").
