Jormangund should lose

Red Ronin stood up to Godzilla. He should win this on his own.

the serpent is thousands of times bigger than these monsters put together. If size is what we judge it by then Jormangund stomps

Also how come red ronnin weighs only 23.5 tons what is he made of soap bubbles. Should be at leat 10 times this (could be a typo)
