Nightfrenzy appears to be a cyborg-like Bakugan with a large sabre made of pure uranium. He can also fly using his robotic-like wings and use them to lash out at opponents.
- Unlike Aeroblitz, who is Pyrus and Haos, Nightfrenzy is completely Darkus.
- This is shown since Uranium Leonidas is the counterpart of Titatium Dragonoid/Fusion Dragonoid.
- Nightfrenzy's original name was supposed to be "Nightfury".
