Bakuryū-Oh is a remote-controlled mecha that takes the entirety of the Earth Defense Class for its operation - this means that if there is fighting among the Class's students or someone is absent, it is at a disadvantage as not everyone within the Class would be able to properly control it to its fullest extent, and in the event of an absence, its operation would require Earth Defense Class students multitasking in more than one operation duty if someone needs to cover for the absent student.
It has two modes which it changes between via Invincible Transformation:
Bakuryū-Oh posses the following weapons and attacks:
- Attacks: Bakuryū Fire (バクリュウファイヤー Bakuryū Faiyā?)
It also has the ability to join forces with Raijin-Oh via Super Invincible Combination to assemble God Raijin-Oh.
For a time, its dragon form has had no specific name given, meaning it is known as Bakuryū-Oh in both forms. Eventually, the form has a separate name assigned to it: Bakuryū Dragon (バクリュウドラゴン Bakuryū Doragon?).
