Suggested by Destroyer Black Spider is very athletic and can fight with some good hand to hand but he doesn’t have any knockout blows that could defeat Space Godzilla. As a result he will really be on the backfoot the whole time and doesn’t have any proper techniques to try and counter the Kaiju with. Space Godzilla will remain one step ahead and inevitably will land a blow at some point. Once he does then the match is all over. Space Godzilla wins.
