Suggested by Destroyer Kid Flash is a talented speedster who has been through a lot of difficult fights before. He may not have quite as good stats as Barry but he’ll still be able to run rings around Space Godzilla. Pure power isn’t enough to take down a speedster of his caliber. Space Godzilla’s attacks could take Flash down in a few hits, but he would never possibly be able to land a hit on him and that nullifies all of his power. Kid Flash wins.
