Because of watching the tmnt marathon! So this my attempt at a one shot ideas of the turtles being different species. Simon to it: I do not own tmnt just this story.
TAS: teenage alien salamanders, in a au of the turtles being salamandrians as well as being raised by leatherhead as their father as street fighters who protect NYC from Mutants evil aliens and meet April and Miwa( in this she was raised by splinter) who help them on their adventures.
Leonardo: appearance: a 7foot tall salamandrian with blue skin with yellow underbelly spots.
Weapon: A katana blade.
Raphael: appearance a 7foot tall salamandrian with red skin with purple underbelly spots.
Weapon: Tonfa
Donatello : appearance 6foot and 5inchs tall salamandrian with purple skin and green underbelly spots.
Weapon: bo staff
Michelangelo: appearance: a 5foot6 tall salamandrian with orange skin and red underbelly spots
Weapon: nunchucks
So yeah this one idea of a tmnt au! If your interested that you can use it in a fanfic if you want.
