Viras vs. Ebirah and Oodako.
Location: On a sandy beach.
Height and Length: The same as their orginal appearances.
Well, im pretty sure Viras would win, since his spikey head. Ebirah and Oodako don't really got any notable abillities, Ebirah does have a hard exo-skeleton though, so that might be a little problem for Viras.
