Max Tennyson is a hero in Ben 10 (Umut298). He is a human from the planet Earth.
Max is usually a normal man.
Powers and Abilities
Max has Plumber armor.
- Max was supposed to get the Omnitrix, but when Ben found it, his DNA was close enough to Max's that it attached itself to his wrist instead.
- Max was a Magister for at least 5 years.
- In the beta version of the original series, Max originally wasn't a Plumber, he was just an average inventor.
- In Dimension 23, Max died before the Omnitrix reached Earth, leaving Ben 23 with no mentor or moral support until Azmuth 23 took up that position.
- Max's cooking is a running gag throughout the franchise as most humans, (especially Ben, Gwen, and Kevin) find the cuisine to be disgusting, while aliens, (Rook, Xylene, and others) can't get enough of it.
- Characters wearing shirts identical to Max's appear throughout the series as a running gag.
- Max loses his arm in the Limax War, which happens in the future.
