kallark is a member of the strontian race, and was born under shi'ar rule. all strontians are born with the capacity for great strength and various superpowers, but can only use them when they are completely devoted to a purpose. fearing a strontian rebellion, the shi'ar emperor ordered kallark, among other strontians, to kill the strontian elders. only kallark was devoted enough to carry out the order, and the others were killed when their wavering commitment rendered them weak. as a reward for his actions, kallark was named the praetor (leader) of the shi'ar imperial guard.
