and just standing there
PLEASE tell me this literally happened. After his sister thing I know nothing is too lofty to hope for.
How do you parody that?
You know... I actually thought of a way, at least briefly.
First, you play up the fawning thing. Rather than a cluster of girls just standing there talking about how awesome his ability to eat food is, you go full clothing explosion panting about how she can't take it any more. Then, she powers up into an over the top DBZ villain from sheer lust while monologuing this fact. This of course shatters most of the planet, so the resulting fight takes place on a brilliant shattered hellscape.
Said fight then consists of her attempting to attack in some manner, followed by him instantly incapacitating her and monologuing (in a dull, emotionless voice, of course) about how he did it. Said explanation is entirely stupid and roundabout, and can continue long after the villain has died from said attack if you'd like, though I'd avoid that to keep things moving. Don't wanna emulate it too well.
Our grand protagonist, now afloat in a void, proceeds to instantly teleport three galaxies over to a specific planet, where he enrolls in high school while a bunch of literal moustache-twirling villains gloat about how they're going to femclone him to give him a balancer, at which point he'll be perfect for their schemes. Within a few days of arriving he'll remember he had to do something and instantly obliterate whatever subcontinent the local notChinese were standing on at the time.
So yes, I believe it could be done, though mainly by going Gurren Lagann on it and narrative focus tricks.
