Not much can be told of Dead's Kyle personality other than that he had a penchant for murder and was in the process of losing his mind during his trial.
Dead Kyle had the appearance of a man in his early twenties. He was of African-American descent and wore his black hair in dredlocks. He wore mostly military uniforms when working as a member of Market Maker until he was cut loose a couple of years prior to the start of B the Beginning.
His adoptive father was a navy man.
