Viper Helios (Japanese version Helios (ヘリオス, Heriosu?)) is Spectra Phantom's Guardian Bakugan in Bakugan: New Vestroia. He was later upgraded to Cyborg Helios, then Helios MK2, and then finally Infinity Helios in Bakugan: Mechtanium Surge.
Viper Helios is a mean spirited dragon-like Bakugan. Spikes cover its arms and shoulders while hardened rumpled skin protects its legs from attacks. Horns point in both directions to defend its head. Colossal wings allow Viper Helios to fly avoiding attacks. It uses its fire breathing ability to melt oncoming artillery. Its long tail is used to fend off opponents during a battle.
He was first seen fighting Blade Tigrerra and Nemus. He defeats Blade Tigrerra who saved Nemus's life, and captured her. Later, he uses Tigrerra's defeat and capture to taunt Drago in a battle. When the Resistance, Spectra, Lync, and Gus are stuck on Earth, he helped Spectra capture Dan's Bakugan Drago with a forbidden card. He faced Apollonir in a rematch against Dan, but was beat easily even with Metalfencer. Professor Clay turns him into a Cyborg Bakugan to become the ultimate Bakugan. He was upgraded into Cyborg Helios, and later Helios MK2.
