Season 2Perseus first appeared in W-Episode 01, where it was found in the limited edition Space Hero Senshiman Custom Figure box. Hiro tried to use it but couldn't control it properly. Later, Hiro tried to use it again and managed to control it thanks to Ban's guidance. Hiro used Perseus again in the Tokio Sia Department Store and managed to destroy some of the rampaging LBXs.
In W-Episode 02, Hiro used it to destoy the rampaging Inbit when he was on his way to Seeker Headquarters. Hiro used it again to fight against the rampaging LBXs that were guarding the Seeker Headquarters and used Cosmo Slash for the first time.
In W-Episode 03, Hiro sent it out alongside Ban's Elysion during their trip to Shibuya Town in order to assist Ran and Minerva after she and her friend are attacked by Achilles Deed, Oni Kunoichi, and Hunter Kiba. Perseus uses it's swords to block Hunter Kiba's shots to get close. When Minerva distracts Kiba by jumping in the air, Hiro has Perseus slash away the rifle for Minerva to finish the dark Hunter with a dropkick. Perseus joins Elysion and Minerva against Achilles Deed, but the battle ends after Deed activates Demonic Form and shrugs off their attacks.
In W-Epiosde 23, it battles Kirito's Hakai-O with Ryubei and Jeanne D. However, it was defeated because of Hiro's lack of focus during the battle, leaving Perseus wide open for being attacked. Perseus was then repaired and remodeled alongside Elysion and Minerva. It made its debut in Episode 24, capable of using Strike Mode and as main body for Sigma Orbis.
