(Please note that Dual Elfins ball form in the game is correct, but the Bakugan form is incorrect.)
Defenders of the Core Ability Cards:
- Broken Heart: Elfin fires an energy beam that stuns and damages opponents.
- Aquos Dive: Triggers a powerful combo attack.
- Aqua Bubble: Generates a shield to deflect shots.
- Water Sphere: Elfin creates huge, explosive water spheres.
- In the video game called Bakugan: Defenders of the Core, the evolved form of Elfin shares its ball form and name with Dual Elfin, but has the Bakugan form of Minx Elfin.
