Ranger Powers, Weapons, and Zords
Aoyama can transform into Blue Bat Ranger using his Legend Buckle upon forming a contract with his zord, Darkwing. In comparison to Akame, Aoyama has lower kicking power but higher jump height and running speed.

Aoyama can arm himself with the Wing Lancer (ウイングランサー Uingu Ransā), a lance derived from Darkwing's tail, by using his Sword Vent. The remainder of Darkwing's body can be mounted on Knight's back, where its wings become a cape. This can be done by using either his Guard Vent or Final Vent. (However, Aoyama is often seen transforming into Blue Ranger with the cape already equipped). When using the Guard Vent card, the wings are in their original form and close around Aoyama to form the Wing Wall in order to protect him from attacks.

Using his Final Vent allows Aoyama to perform his finisher, the Flying Lancer (飛翔斬 Hishōzan), which equips him the Wing Lancer and Darkwing's cape form if he does not already possess them. Aoyama then jumps into the air and performs a dropkick while holding the Wing Lancer downward, resulting in it being parallel to his legs. Finally, Aoyama's cape forms a drill around him before he strikes the enemy.

Aoyama can piloting his Darkwing jet fighter to become a left hand mode of the Legend Megazord.
