- Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
- Originally, Gunner MacKay was killed in action in Markovia in 1943 fighting the Anti-Monitor's Shadow Demons during the Crisis on Infinite Earths event. He was later resurrected as a member of the Creature Commandos.
