Max Tennyson (Classic)/Background

Max spent his childhood summers on his Uncle Jedediah's farm, where he learned about the merits of hard work.
Max, under the effects of Zombozo's happiness-draining, mentioned having been afraid of heights as a kid and to beat his fear he climbed up to the top of the water tower and "scared the fear" right out of him.Last Laugh
Max has a childhood friend named Donovan Grand Smith,They Lurk Below who says that Max always worried and was never a risk-taker like him. 30 years earlier, Donovan and Max had both been broke when Donovan offered Max a business opportunity, which he turned down. Max later became a Plumber (most people thought Max was just a regular plumber), establishing that Max's career as a Plumber lasted for about 28 years before he retired (Max mentioned that after 28 years on the job, he'd never figured out who was behind the Bermuda Triangle).
In Blukic and Driba Go to Area 51, 
In Moonstruck, Max revealed his past where he first met Verdona. When he was about 17, he was a First Lieutenant and pilot in the Air Force. During a mission, he saw and followed a spaceship. He blasted it, but the spaceship got away and Max's plane crashed. He talked to the commander about the spaceship, which made him an astronaut and gave him a mission to be the first man on the Moon. While at a diner, he met Verdona in her human form and fell in love with her. Suddenly, a humanoid robot came and attacked Verdona. Max saved her and left to a faraway desert where the robot couldn't find them. Verdona explained to Max that she is not from Earth, she is from another planet. The robot that chased them was a sentient robot called a Synthroid and had left a bracelet on Verdona's wrist, which made her unable to do most her powers, save for her telepathy. She revealed to Max that she was the one in the spaceship he saw before she read Max's mind. She told him that their minds were now linked. She also revealed that the Synthroid wanted her to be a battery-like energy source for their planet (since she is an energy being). The Synthroid came back and kidnapped Verdona, but Max used his mind to locate Verdona (since Verdona had said their minds were now linked). He (with some help from Magister Labrid) saved Verdona and destroyed the Synthroid. The bracelet that prevented Verdona from using her mana powers fell off. Revealing her true form, she asked Max whether he would go with her back to Anodyne. However, Max declined, and with a kiss, they parted.
The Monday after he met Verdona, Max went into the astronaut training program. Max would have been the first man on the moon, but he left NASA prior to Apollo 11 as he was recruited into the Plumbers by Magister Labrid. In his own words, he just "took his step for mankind in other ways". Shortly after, it was revealed that he did in fact go into space, just not with NASA.
While in the Plumbers, Max befriended Wes Green, a Plumber in the extradimensional control division.Benwolf At one point, the two sent a Yeti in the Himalayas back to its home dimension. Max met Wes' granddaughter, Kai Green, when she was around toddler age.
Max went to the moon three times and stayed at a secret lunar Plumber base.
Max went up against Vilgax several times in the late 60's and early 70's.
Max retired from the Plumbers in his late 50's.
After Sheelane crash-landed on Earth, Max helped Mr. Baumann get her and her ship to an underground lake.The Ballad of Mr. Baumann
