Nell (Japanese: キャサリン Catherine) is an Orange Star CO. She is also the player's instructor in field training and assists the player in Campaign by giving hints and strategical advice. Her little sister Rachel takes Nell's place as the player's advisor in Advance Wars: Dual Strike. Nell attended military school with Grit and Max.
Nell was born under a lucky star, giving her units a Luck bonus of 15% instead of the standard 10%.
Lucky Star - Increase Nell's Luck to 60%. All of her units also get a 10% boost in defence, and in Advance Wars: Dual Strike they also get 10% boost in offence. Interestingly, in Advance Wars 2: Black Hole Rising her units are stated to damage multiple foes, though nothing of this sort ever actually happens.
Lady Luck - Raises Nell's Luck to 100%. All of her units also get a 10% boost in defence, and in Advance Wars: Dual Strike they also get 10% boost in offence. Interestingly, the in-game info of Advance Wars 2: Black Hole Rising states her units to damage multiple foes, though nothing of this sort ever happens.
Fair Warning: Bear in mind, luck is still luck. That damage counter may actually be right, and that could spell the end of your brave little recon.
Nell has Tag Breaks with the following COs:
- Rachel, 130%, "Windfall" (3 stars) Absurd levels of luck coupled with free missiles... a very scary tag indeed.
- Andy, 105%
- Max, 105%
- Sami, 105%
- Von Bolt, 90%
"Don't hate me just because I'm lucky!"
"Pull together, everyone!"
"Everything will work out!"
"This will bring me luck!"
Rachel: "Not bad, huh, Sis? Whooo! Yeah! We rule! Yeah!"
Nell: "Excitable, aren't you?"
Nell: "Huh. We won. Lucky us."
Rachel: "Don't be such a downer, Nell. Smiling won't kill you!"
