What the hell is a "Cosmic" Rimiru...

Its just LN Rimiru

LN Rimiru literally lived in Japan pre Reincarnation...

He knows who Xeno Gameku is and prob has played DBHWM before...

Why should he lose?

Why should he win?

He just gives the W to Goku and leaves

It's a fanmade version of him.

I am a big TTIGRAAS fan and never heard of him

And if he's fan made he auto clears
