First appearance Get Psyched

Jelldon is a jellyfish-like Bakugan. It bears a slight resemblance to Jetro from Bakugan: Gundalian Invaders.



Jelldon can use its stingers to shock enemies. It is one of the most commonly seen Bakugan in the anime. His ball form is the only Bakugan ball form that isn't completely solid, as it has a crystal-like upper half. He resembles a jellyfish.


Bakugan: New Vestroia[edit]

It was used in Get Psyched, Marucho's Mission, Cyber Nightmare, and What's the Plan?. A Haos Jelldon is owned by Baron Leltoy, an Aquos Jelldon was owned by Mylene Farrow, a Pyrus Jelldon is owned by a Vestal Battler in the tournament of Alpha City and another one in Cyber Nightmare was seen on Keith's computer.

Baron's Jelldon was nearly captured by Shadow Prove, and Mylene's was thrown out alongside Freezer and Fly Beetle.

Physical Game[edit]

Although Jelldon was never released as a toy, it does appear on a couple of cards. In both of them, Jelldon is seen in the Aquos attribute.


  • Its legs resemble Fencer's.
  • Its ball form appears to be the lower half of Jetro or Fencer with the translucent upper half of a Bakugan.
  • In Bakugan form, it resembles Tentaclear and Irisca.
  • Jelldon has never been shown using an actual ability or even an attack.
