Accel Leon is first shown to have immense rapid fire but limited accuracy when it was used to battle Cobalt Blade and Yamato in the Leon Stage of the Five Field Challenges. Accel Leon is next used to battle Liena's Garnet Wind to no contest. Accel Leon debuts its special ability, "Lion Claw", while battling Manual and his B-Daman. Accel Leon and Cobalt Saber are able to combine their special shots to form the "Lion Claw Power Blast" to defeat Manual in his Revenge Mode.

- Accel Leon's speed-loading magazine, as well as B-Daman CrossFire's Quick Loader Magazine Tune-Up Gear, are descended from the Super B-Daman Speed Loader Magazine I and Speed Loader Magazine II OS Parts.
- Only the Sonokong and Takara Tomy versions come set with the speed-loader magazine. While the Hasbro version comes with the Extended Trigger, it instead features a magazine attachment much like Proto One's instead.
