Max Tennyson (Classic)/Omniverse flashbacks

In A Jolt From the Past, both 11-year-old Ben had just defeated the Nosedeenians using Feedback. Max arrived with rubber blankets, saying how he was glad that Ben still needed them.
In Trouble Helix, Max went along with Ben and Gwen to Galvan Prime to tell Azmuth about a malfunction in the Omnitrix which trapped Ben as a different alien every week. Azmuth told Max to come back in two years to which angered him. Azmuth then decided to fix the Omnitrix after Ben (as XLR8) started messing with his inventions. Max then told the kids to wait outside while he talked with Azmuth. Max was seen later who tried to help in taking down Malware and rescue Albedo. The plan nearly fell through as Albedo had tampered with the Helix trying to destroy Malware rather than save him, which changed Malware's form. 
In Malefactor, Max brought Ben and Gwen to Mt. Rushmore and showed them the smuggled Psycholeopterran. The alarm suddenly went off and Max, Ben, and Gwen went off to find the source of the problem. It turned out to be Malware's doing and Ben proceeded to fight him, but the Omnitrix timed out. Max then blasted Malware with a Tachyon Cannon but Malware absorbed the weapon. Max watched as Ben continued to fight Malware as Feedback but then Malware left saying he already had what he came for.
In Of Predators and Prey: Part 2, Max drove the Rustbucket 2 into Terroranchula but it just pushed him aside. Ben managed to fight the creature as Feedback but both the Omnitrix and the Nemetrix timed out and the creature turned out to be none other than Phil. Max watched as Phil was suddenly transported away.
In Showdown: Part 1, Max, along with Gwen and Azmuth, held an intervention for Ben to convince him to stop overusing Feedback. Ben, greatly upset, left the Rustbucket without saying much.
In Ben Again, Max was confused with the sudden mind change between 11-year-old and 16-year-old Ben. Max soon learned from Professor Paradox that it was Eon's doing and he watched as the Bens used Clockwork to make everything right again.
