Contestir (コンテスター, Kontesutā?) is a knight-like Gundalian Bakugan and the Guardian Bakugan of Zenet Surrow in Gundalian Invaders. His Battle Gear is Spartablaster. Unlike other Bakugan, his Battle Gear mounts on his top half. He is part of the BakuStand series.
Contestir and Zenet are parts of Ren’s team. Contestir's attack style is fast and he unleashes glowing waves of attacking energy from the horns on his head. He is wise, good-natured and sly. Contestir is dignified and has a calm personality.
In Confrontation, Zenet used him against Drago and Linehalt. He and Zenet are shown to argue a lot but are able to work well together. He defeated Linehalt with ease, later sacrificing himself to give Rubanoid the means to defeat Drago.
Zenet used him again in Escape From Darkness, battling Fabia and Avatar Marucho alongside Phosphos. The two successfully battled and beat Aranaut and his clone, though Phosphos appeared to do most of the fighting.
In Partners 'Til the End, he battled alongside Krakix against Lumino Dragonoid and Hawktor but lost. Later, he was attacked by Krakix for failing. He and Zenet were reunited to which she remarked that Gundalians are loyal to no one to which Contestir replies they are loyal to each other, to which Zenet agrees with and apologizes that it took her so long to realize that.
In Broken Spell, he continued to battle the Castle Knights but was released along with Zenet when Kazarina's spell was lifted.
