Oro-whateverhisnameis, wasn't part of the original. If it wasn't fighting Saitama, I wonder whether Tatsumaki could take it on or not. There's a lot of people that Saitama fights that I wonder how well she'd handle them. Most of them she'd obliterate, but some, I have to wonder. Like with the aliens, I think she'd lose. The telekinesis guy probably never got a chance to show his true power as it seemed he was finished off before he could.
Whoever read the original, I'm purposefully avoiding spoilers, so please don't respond referencing anything that is a potential spoiler. 😘
