About the AUEdit

In this AU, the members of the Big Four (and other such characters) are portrayed as characters from Teenage Mutant Ninja Turtles, most commonly as the four brothers: Leonardo, Donatello, Raphael and Michelangelo (as turtles or four skills "human" warriors of the martial-arts).

The four can also be friends with the brothers and their allies.

Featured CharactersEdit

The Big FourEdit

Hiccup Horrendous Haddock IIIEdit

Hiccup's leadership, sword and instincts casts him as Leonardo (Leo), while his 'technological' genius makes him Donatello (Donnie). Hiccup can also be cast be a Teenage Mutant Ninja Dragon, instead of a turtle with Fishlegs, Snotlout and Tuffnut.

Jack FrostEdit

Because of Jack's choice in blue, fans see him as Leo, while his staff casts him as Donnie. Fans also see him as Raphael (Raph) or Michelangelo (Mikey).

Merida DunBrochEdit

Fans see Merida as a female Raph. Due to the fact, they have such fiery and stubborn personalities.

Rapunzel CoronaEdit

Rapunzel's playfulness (from when she first spet out of her tower) casts her as Mikey, she can also be cast as April O'Neil, a human girl that befriends the brothers and helps to keep them a secret from the city above their underground home. Rapunzel can also be cast as the fifth and only female turtle, Venus de Milo/Mei Pieh Chi.

Extra CharactersEdit

Nicholas St. NorthEdit

Fans see North as Splinter. Due to the fact that he is a father like figure to Jack, a master swordsman and wears a red coat that is a bit like Splinter's rob.


Yokai's mask, being able to take on an army by himself and was set to be a head of criminal organization in one of the original ideas of Big Hero 6, Yokai is cast as Shredder.

Pitch BlackEdit

Fans see Pitch as the turtle brother's nemeses, the Shredder. With his Nightmares as his ninja henchmen.


When the Dreamdorks play (three of) the brothers, Guy is commonly portrayed as Donatello. As the two characters are light on their feet, use their heads and like to come up with many new ideas and items that can be useful.

The Stabbington BrothersEdit

Being two criminals that work together, aren't afraid to break some skulls and spend time as henchmen, easily casts the two as Bebop and Rocksteady.
