They're both the children of insane and villainous mad scientists who were subjected to experiments from a young age, giving them several psychological issues and the ability to manipulate their own blood and use it either to fight or to heal themselves. Their psychological problems lead to them experiencing violent changes in personality at a whim, going from mostly harmless and socially awkward to violent and psychotic in an instant. In spite of this, they end up befriending the main heroes since they were the first people they met to treat them with kindness, and though they do end up fighting with the heroes, in the end they still remain friends.
