|First appearance||The Story of Vestroia|
Tentaclear (ルミナ・フラッシャル Rumina Furasharu, Original version Lumina Flashal) is a Bakugan with the Haos attribute, and is Julio Santana's Guardian Bakugan. It is a hovering eye with six tentacles around it.
Tentaclear is an enormous chilling single eye emitting a shining beam to blind its enemy. Six lethal stinging tentacles surround the eye as it hovers in battle.
Tentaclear is unable to speak, perhaps because of his lack of a mouth. This proves to be a bad thing for Julio Santana because Harpus was making fun of him and Tentaclear couldn't speak for either side.
