Suggested by Destroyer Wybie is a nice kid but he’s not exactly a fighter. I don’t really think there is anything he could actually do to stop Jirass. Jirass is a Kaiju and so his durability exceeds that of what any normal human can hope to dish out in terms of damage. Jirass may not be very fast but it doesn’t matter since his size will allow him to cross such a distance with ease. Jirass wins.
