|First appearance||The Battle Begins|
Serpenoid (Japanese version Serpent (サーペント Sāpento)) is a snake-like Bakugan.
Serpenoid is a slithering monster that can wrap itself around a foe, squeezing the life out of it. Serpenoid's attack is extremely fast, but the suffering it inflicts is slow and methodical. Its power grows as the life of its enemies is slowly sucked away, leaving them with nothing.
In the Bakugan anime, Serpenoid appears in the form of a large snake. With its winding body, it is commonly known to attack its opponents by coiling itself around them and draining them with its stinger until there's nothing left of the enemy.
Dan Kuso used a Pyrus Serpenoid in many episodes. Its was the first bakugan he used in the series. Unfortuately, Dan's Serpenoid has been sent to the Doom Dimension. Pyrus Serpenoids fought for Naga. An Aquos one and a Subterra one was seen fighting Naga's forces.
Serpenoid opens with a head popping up and a tail going downward. The tip of the tail touches the bottom of the head when closed. When opened, a small part of the tail detaches itself, creating an extension of the tail. It was released in all Attributes. In Japan, its Subterra version in BCV-02 comes with 330 Gs or 420 Gs. A Darkus Serpenoid has 400 Gs.
Serpenoid is one of the three Bakugan first introduced in the first video game, alongside Saurus and Juggernoid. Its base G Power is 150 Gs in the Bakugan Store, making it the weakest Bakugan playable. Serpenoids are available in every attribute.
- Serpenoid was Dan's first Bakugan to be shown in Bakugan form.
- In ball form, it looks similar to Rattleoid.
