Steeler first appeared in Zap!! A Rising Beam of Light as a Dynamaxed Pokémon in a Max Raid Battle. He went up against Henry, Casey, and two Team Yell Grunts. Using his Guts Ability, he was able to quickly defeat the grunt's Pokémon, but ended up dropping his metal beam when it became overheated. While distracted, Henry had his Lancelot use Brave Bird on him to knock him out. Henry then caught the Muscular Pokémon, naming him Steeler.
In Watch Out!! Strong Rivals, Steeler was used as Henry's first Pokémon in his fight against Milo. With his steel beam, Steeler finished off Gossifleur with a powerful Close Combat. He was then recalled in favor of Lancelot.
In Blazing!! Bede's Feelings, Bede, angry at Henry's relationship with Chairman Rose, attacked him with his Galarian Ponyta. Not trusting the gear of his other Pokémon, Henry choose Steeler to defend him. Steeler's attempt at Hammer Arm missed, made all the worse by Ponyta's use of Agility. Steeler countered with Rock Slide, creating a dust cloud. As the dust cleared, Bede spotted Steeler and had Ponyta attack. However, only the steel beam was there. As they questioned where Steeler was, he emerged from the rocks and knocked Ponyta out.
In Gulp Gulp!! Pokémon, Steeler was one of the three Pokémon Henry brought to use in his gym battle against Kabu.
In Rising!! Opal of Ballonlea, Steeler was used as Henry's second Pokémon in his fight against Opal. He quickly defeated her Togekiss with a single Rock Slide. He was then called back for Lancelot.
