Plumber Suit and Weapons
Paul Eiding (Original series, Alien Force and Ultimate Alien)
Grandpa Max is a Plumber, who takes his grandchildren Ben and Gwen on a cross-country trip, during which Ben discovers an alien watch, the Omnitrix. His grandson uses the watch to become the superhero "Ben 10". Max helps his grandchild fight bad guys and aliens, he also teaches Ben to use the watch responsibly. During their adventures, Gwen and Ben question Max's uncanny knowledge and the fact he doesn't seem to be bothered by all the weirdness they encounter. It is eventually revealed that Max and the alien warlord Vilgax are old enemies.
In the episode Truth, Max reveals he is part of inter-galactic police force known as The Plumbers and that he had fought and defeat Vilgax years before. During the episode he meets his old partner Phil. He discovers Phil stole the Null Void Projector, using it to make easy money, by freeing the aliens who the Plumbers had already captured, then fighting and catching them for profit.
In the episode Perfect Day, Max has received a wedgie from Cash and JT.
In the episode The Visitor, it is revealed the Omnitrix was originally sent to Max by the alien Xylene (who was Max's old flame) and accidentally ended up in the possession of his grandson, Ben.
Ben 10:Alien ForceEdit
n Ben 10: Alien Force, Max looks mostly the same, Max in Alien Forcesave for more wrinkles and a darker red shirt with whiter hair. In the episode Ben 10 Returns, he leaves a transmission for Ben stating that he is investigating renewed alien activity on Earth and claims that he has the Omnitrix. An image of a DNAlien flickers at the end of the transmission. It is conceivable from this, that Max was wearing an ID-Mask and that the DNAlien in the teaser was actually Max (the voice of the DNAlien is confirmed as Paul Eiding), implicating himself as a mole to distract the Highbreed from Ben (whom, with the Omnitrix, poses a greater threat). The message was probably in code, telling Ben to put on the Omnitrix once more. An earlier theory suggested that the hologram might have been that of a DNAlien who wanted to keep Ben out of their business, but instead made a big mistake. In the episode Max Out, Max destroys a Xenocyte hatchery by detonating a Null Void Projector, which after removing its focusing lens, makes a "pretty good imitation of a hand grenade" and produces an explosion that covers over half a mile wide. Max appeared to have been killed in the blast, but was instead sent to the Null Void (episode: Voided), where he, calling himself "The Wrench", fought Dr. Animo, who was calling himself "D'Void". He has since appeared in the two-part episode War of the Worlds to aid Ben in his battle with the Highbreed along with the "Plumber Helpers". He and the Plumber Kids also appear in the two-part episode Vengeance of Vilgax.
