Phillip Karnowsky is a former Navy SEAL. After his wife's murder, Phillip embarked on a killing spree on criminals released on technicalities.
After killing his wife's killer, he started looking for more targets, all of whom were criminals.
After the Guardian apprehended a target and left, Phillip killed the criminal. A surveillance camera outside a pub filmed the killing, but his appearance was foreshadowed, leading the public to believe it was the Guardian's work.
Phillip and the Guardian had a confrontation after he killed a drug dealer. The fight was interrupted by the arrival of the NCPD. Soon, he was arrested after James defeated him in battle, clearing his name in the process.
- Phillip Karnowsky first appeared in Superman Annual Vol 2 #2 (1988) as the villain, Barrage. However, on the show he was never referred to as "Barrage". He is a villain of both Superman and Maggie Sawyer.
