During his relationship with Donna Troy, Rayner engaged in combat training with his then-girlfriend. During his first battle with Fatality, he proved to be a formidable fighter and was able to defeat her when his ring was drained. In nearly every encounter with Fatality since that incident, Kyle would use his combat skills to defeat her rather than his ring in order to maintain an element of surprise (she expected him to use his ring) or when his ring is drained or absent during battles. As a member of the Justice League, Kyle occasionally would train in the League's combat training systems on the Watchtower and under the tutelage of combat-experienced Leaguers, such as Batman. Even though Rayner is now a skilled hand-to-hand combatant, having been trained by the Dark Knight himself, he is not an expert in hand-to-hand; for example, while he initially held his own in a hand-to-hand fight with Sinestro, the villain proved to be a better fighter due to his greater experience.
