Sidearm is a less than capable villain of Superboy. Superboy continually beats him and mocks him while he does it. He continually calls Side Arm by the wrong name like:
- Armchair
- Armpit
- Backside
- Side Effect
- Sideboard
- Sideburn
- Sidecar
- Sidedish
- Sidekick
- Sidesaddle
- Sidesplit
- Sidestep
- Sidester
- Sideswipe
- Sidetrack
- Sidewalk
This of course tick Sidearm off.
Sidearm became a member during one of the Suicide Squad incarnations and during the solo mission was a casualty.
