- This version of Thunderbolt, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Peter Cannon was not owned by Charlton Comics; he was licensed to Charlton by his creator Pete Morisi. So when DC "bought" Peter Cannon from Charlton in 1983, they really only bought Charlton's license to publish Peter Cannon. When the original agreement between Charlton and Morisi expired, DC negotiated with Morisi (and/or his estate) directly to extend it for a while. But eventually, DC let the license lapse, and Morisi's estate has since licensed Peter Cannon to other publishers. As of 2012 , DC has no rights to publish Peter Cannon.
