Sectanoid (セクタノイド, Sekutanoido?) is a mosquito-like Bakugan that debuts in Bakugan: Evolutions. It is the new Partner Bakugan of China Riot.
In "Lia and Riot!", Sectanoid participated in a tag battle of China and Lia against Chad and Chet Chipman. When Sectanoid is almost beaten by Chet's Serpillious, Riot gets impressed by how Lia and Pegatrix are willing to help Riot and Sectanoid, allowing an Elemental Core to appear in front of Riot to summon then Nanogan Sludgem and win the battle.
In "Lia and Athena", Sectanoid achieved Strength Mode while battling Colossus Strength Mode.
Sectanoid Strength Mode (セクタノイド ストレングモード, Sekutanoido Sutorengu Mōdo?) is an Elemental Evolved Form of Sectanoid in Bakugan: Evolutions. It is represented in the Physical Game as Platinum Sectanoid.
- In Bakugan: Evolutions printed designs were added to Bakugan depending on their Faction, unlike other Bakugan from that season Sectanoid not only had the printed designs of the toys Faction but also had the Ventus designs molded onto the toy itself.
