Caio's fam crimes refer to the acts of familicide committed by Caio, a member of Isg and considered one of its "pillars", against his own family and the families of his victims. The methods included stabbing, shooting, burning, freezing, dismemberment, torture, explosions, tramplings, etc. However, not everyone agrees with his actions, especially on the internet, as he tends to exterminate the entire line or family tree of those he sees as enemies or foes. Despite this, the bodies of Caio's family and the families of his victims have gone missing mostly, which has caused controversy around his identity and what he seems to be. Caio is currently known as a professionally trained, rich and powerful genocidal murderer, whose fame has spread because of his actions.
