He is a former Mafia enforcer and associate of Antonio "Tony Twist" Twistelli, the Don of New York, and is now a vigilante seeking revenge on The Family.

When he wanted out of the mob Twistelli had him captured and shipped to Germany, where he was used as the guinea pig for Project: TREMOR, the mafia's first attempt to create a supersoldier.

The newly dubbed "Tremor" was a failure, as his free will and disgust for what he had become overwhelmed any type of loyalty he had for the mafia.

As Richard revealed himself to his brother, David couldn't understand or believe what was going on because of his own guilt and his hatred for Tremor and began to unload his weapon into him.

Spawn only saw part of what had happened and attacked David, severely injuring his leg and enraging Tremor.
