Since the calamity is from hell I gave him a bunch of spikes and red veins going through him. I gave him his calamity symbol on his chest. Made him a giant bland on his right arm so can use it to cause agony because he is the god of agony. I also gave him a weird or evil looking face cause the boy does damage to the area he is in. Also he has hole that leak black liquid that can summons his little minions.
