Jin (ジン, Jin?) was the former Commander of Neathian forces. He was Fabia's fiance, so he might be have been the same age or a little older, than Fabia. He was killed by a blast from Lumagrowl's Barias Gear before the start of Bakugan: Gundalian Invaders.
His first appearance was in a flashback in Forgiveness. He lost in battle, Aranaut was taken from him and he was killed by Kazarina and Lumagrowl. When Fabia rescued Aranaut from Gundalia it was believed the torture Kazarina put Aranaut through made him forget his memories of Jin. However, Aranaut was actually lying on Fabia's behalf due to the sadness she felt when he died.
Bakugan: Gundalian Invaders
- Haos Aranaut (Guardian Bakugan) (Taken by Kazarina, but Fabia rescued him back and belonged with her; now used by Elright)
- Silver Battle Crusher (Battle Gear) (Belongs to Fabia now when Aranaut was rescued, now Captain Elright.)
- In Japanese, Jin is a unisex name that means "benevolence"
- Jin is the only Neathian shown to die in the anime so far (Sellon does not count due to being an artificial creature).
