Suggested by Sonic Astaroth is a bruiser type of fighter. He goes in close and lands punishing blows but that won’t be enough here. Mainly that is because Meruem is just flat out stronger than Astaroth. In terms of physical abilities and long range options, Meruem has the massive advantage. There’s no way that Astaroth can even hope to counter his abilities and ultimately he will be going down here. Meruem wins.
