Thus far, very little has been revealed regarding the background of the first villain to call himself Arsenal, including his real name.
What is known is that he was a midget, and it has been conjectured that resentment over his small stature… and the lack of respect and dignity he was shown as he matured to adulthood… combined to create an antisocial personality within him, prompting him to turn to a life of crime. At some point, he showed a keen inventive mind by creating a robotic body for himself to inhabit, and equipping this robot with a wide variety of deadly weapons. Dubbing himself Arsenal, he hired himself out as a paid assassin.
