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.
Viper Helios was a VexosBakugan and he tries to capture all the 6 Bakugan that saved Vestroia. Viper Helios enjoys having Bakugan to battle and obeys every command from Spectra.
He was first seen fighting Blade Tigrerra and Nemus. He defeats Blade Tigrerra who saved Nemus' life and captured her. He is also shown in a flashback defeating a pryas Soris and another flashback where he defeats Premo Vulcan in the Alpha City tornment. After Vulcan gets defeated by Ingram Spectra uses Helios to brawl Drago where 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, eventually into Helios MK2 and, finally, into Infinity Helios.
