ok let's see how i do it.
End of season 1, Max and Steel made a feat of 71.2 Teratons, this was after a hard fight against the elementors and being drained by dread so he wasn't 100%, after that he grew rapidly in power (said by someone who drained much of his power before and after the 71.2 Teratons feat) to casually shoot U. Elementor with just his force mode, when before his cannon mode (which was Max's strong max mode but consumed more energy) only stunned him.
He eventually faced Mega Elementor in a one-on-one battle and barely won with the use of strategy, right after that, with the help of Torbolt he more easily defeated Mega Elementor(that actually Turbolt can only move Mega elementor and use the balance against the elementors but he did almost no harm to they).
all that was before facing Morphos
who copied Max stats, became stronger due to its ractive evolution and defeated Max, eventually after
the turbo chamber they became stronger but
still no match for morphos so they were forced to combine their Turbo modes, considering them to be more powerful than before.
Also, Mash has to knock out Steel who can control Max's body and even if Mash knocks out max and Steel, he will automatically be taken to the room where he will perform the Duo Strike
stealth mode is indestructible even for characters that can sense Max's energy signature.
Max is comparable to his father who was drained of his stamina and power by makino for 16 years straight non-stop in the Alphalink, the main reason why Max gets tired is due to the excessive use of energy in his fights (goes low 5- B in some battles where he spend more energy) and because he faces enemies with better absorption
about max heat being hotter than lightning was a joke, but the sonic attack is constant, So even if Mash can recover from having his eardrums broke, it won't be that soon.
but hey, this doesn't matter, a lot of Mash have a Skill advantage so I'm sure he'll come up with an absurd strategy to win.
