I asked Ant to reopen this thread cause I think it's unfair how you came here decided all on your own and closed the thread without giving me a chance to reply. I hope you don't close it again, I might not be able to respond immediately.
The bold part here is the issue. You said "which is why Saitama could be launched at high speeds", which is practically wrong. This isn't what the quote actually states.
It states: "I basically resolved the whole question of heat friction by wrapping Saitama in Boros's energy while he was being launched near the speed of light".
Nowhere is it stated that the energy or the lack of heat friction allowed to launch Saitama at near Light Speed like you said. It only said that the lack of heat friction allowed Saitama's clothes to remain intact, that's it. Everything else is your addition to the statement, not canon.
The key part is "his", not anyone who is wrapped in his energy.
I never denied MB gives super speed, again, the key part is "his", not everybody else's.
The issue here is bold italic statement you made. Never ever is it stated that Boros can move at near-lightspeed, you basically wrote this and linked a calc to his profile that doesn't support what you wrote in there. If that link has a statement "Boros can move at near-lightspeed" as you wrote on the link itself, then quote it.
Your whole argument stands on the idea of his energy moving things at near Light Speed, which is as I already mentioned, wrong. I want you to try and respond to everything I wrote.
