Are you confusing High Tension for Ultra Smash? Because he needs 7 super emeralds to become Ultra, so there's no friggin' way he can just "suddenly have access" to it.

If you mean High Tension then that would make much more sense as yeah, the page doesn't actually explain how he gets it. I did drop some hints though, as the entry on High Tension in his subpage states:

"High Tension is an ability mostly anyone can learn, through the proper training. However, the people in Smash's family are somewhat of an exception; they cannot achieve this through regular methods. For them, this potential is locked away until certain requirements are met. The only known one so far is to survive a beatdown so brutal that it leaves them near death. High Tension then activates for them as a desperation skill, unlocking the potential to use it freely in the future."

I also state when it happens in my episode summaries of my series page, but that's a different page so it probably shouldn't count. I admit I never go into detail on how he mastered High Tension either, as that was part of Roleplay:Cosmic Championship, which E-113:Xi and I only recently finished sorting out a rewrite for it. Even so, mastering High Tension and all that comes right before the end of his whole character development arc, so that's why he seemingly doesn't progress further.

As for weaknesses in his strength, I preferred not to list them on his page because people like to metagame sometimes. I've known some people who were notorious for it. But even then, it's not that hard to figure out if you think about it. He fights with his bare hands and legs. Wouldn't he struggle against certain weapon users? And personality weaknesses? I wrote a whole scene that kind of brings his flaws to light if you're interested. It's not really something I can fit on his page though.
