How Gabby joined the Tourney
Along with Donald Duck and Hack and Slash Smashnikov, Gabby is a mercenary hired by Flintheart Glomgold for his expedition to Atlantis. During the trip, Donald attempts to make conversation with her, during which she reveals that she was raised and trained by an order of blade-wielding warrior monks. After Donald prevents her from harming Scrooge's party upon their arrival at Atlantis, she becomes annoyed with him, and later holds him hostage at Glomgold's order. During the ensuing confrontation between the two groups, Gabby is handily defeated by Webby Vanderquack. After being left to perish by her boss, she approaches Donald sheepishly and asks if she and the Smashnikovs can escape Atlantis in Scrooge's sub, to which they reluctantly agree.
Months later, Gabby joins Scrooge McDuck's remaining forces at the Money Bin in an effort to stop the Moonlander invasion. After Scrooge's motivational speech, Gabby and everyone else march up Killmotor Hill towards McDuck Manor, where the Moonlanders' leader Lunaris' ship is stationed. Once they encounter opposing forces, Gabby jumps in and protects some of the group by deflecting their electricity bolts with her swords. Although she is able to disable most of the Moonlanders' weapons using her throwing knives, she is eventually captured. Gabby is later seen freed among her fellow Duckburgians, after the Moonlanders make peace with them once realizing Lunaris intended to blow up the Earth rather than invade it.
