Helios first appears on screen in a summer tournament, where he horribly defeats half of the participants, among them Gingka's friends. He's only interested in a battle against Gingka's Pegasus however, which he easily wins.
In the duration of the movie, it turns out that Helios works for Bakin's Atlantis cult and that their goal is the revival of Atlantis itself. For this, Helios fights without second thoughts, also defeating Masamune Kadoya, Ryutaro Fukami, Tetsuya Watarigani and Tobio Oike as they challenge him.
Finally, Gingka and his friends challenge him again, on Bakin's boat. Unknown to them, the energy from their battle is used to change the course of a comet passing earth, to hit the planet directly.
Realizing that Bakin has only been using him, Helios decides to battle alongside Gingka to save earth. They go to space to oppose the comet directly and with combined blader skill, they manage to prevent the catastrophe.
