Even when piloting outdated Knightmare Frames such as the "Glasgow", Kallen proves to be a dangerous opponent easily defeating numerous "Sutherlands", despite the "Sutherland" being a more advanced Knightmare. With the radiation arm of her "Guren" Mk-II, Kallen can take down almost any Knightmare Frame in a single attack should they allow her to make physical contact, and later models also have numerous secondary attack modes for mid- and long-range combat. Her Knightmare Frame is also incredibly fast, allowing her to fight on the same level as some of the most advanced Knightmare Frames in the series.
