Ultimate Avatar is a Troll Fic crossover between Avatar: The Last Airbender and Maximum Ride by EllaHayBoyz1234, which can be read on Fanfiction.Net. As it ends abruptly and hasn't been updated since 2011, it is safe to consider it a Dead Fic.
Rainbow Tracey Midnite Patterson Cullen joins the flock from Maximum Ride and develops bird wings. She then also is revealed to be a Avatar - as in not the only one - after going through a portal. Follow her as she meets (heavily-flanderized) characters from both Avatar: The Last Airbender and Maximum Ride, becomes a Mary Sue, and generally acts out badly-written teenage girl fantasies à la My Immortal.
Ultimate Avatar provides examples of:
- Aerith and Bob: Perfectly ordinary names coexist like Cindy or Riley coexist with more unusual names like Jeb or Rainbow, and this is never remarked upon. There's also a character named Angle, and everyone treats this as perfectly normal.
- Alliterative Family: Rainbow and her brother Riley's names both start with an R.
- Annoying Younger Sibling: Rainbow's brother Riley does things like putting worms in her bed, and harasses her to the point where Riley apparently cries every night.
- Creepy Monotone: Implied with Ari, who says "hello" to Rainbow "evilly".
- Dreaming of Things to Come: Rainbow dreams of meeting six strangers with bird wings, and she meets them later that day.
- Funetik Aksent: Max has a inexplicable thick southern drawl that is spelt out phonetically.Max: I hope that we get rid of that Rainbow girl soon. She's movin in on mah mand and stealin' my little sister Angle from me!
- My God, What Have I Done?: Rainbow briefly has a moment in Chapter 6 where she regrets killing a random Fire Nation soldier, but she quickly gets over it once she realizes how sexy Zuko is.
- Real Men Eat Meat: Rainbow's father tells her to eat bacon because she won't build muscle otherwise, despite her protests that she's a "veegin".
- Token Minority:
- Nudge is the token disabled character.
- Iggy is the token person of color.
- Winged Humanoid: Rainbow suddenly grows white angel wings upon meeting Jeb.
