This is how Thomas' duel with Stormer goes in Thomas and Twilight Go To The Hero Factory.
Stormer: Hello there.
Thomas: I've come to stop you Stormer.
Stormer: Ha! Stop me? You think it's funny?!
Thomas: No. But I won't let you get those plans.
[Thomas activates his sword arm and they start fighting]
Thomas: Then your on!
[They continue fighting until Stormer hits Thomas on the head, grabs the plans and climbs up and away]
Stormer: Give it up, you lost.
Thomas: Stormer, I'm sorry I couldn't save you. [blacks out]
Fear: Oh my, Thomas fainted!
Joy: We'd better check if he's alright.
[They run up to Thomas]
Applejack: What in tarnation happened?!
[Ratchet scans Thomas]
