Eleanor (also known as Ella or Ellie) is the little sister of Leonardo, Raphael, Donatello and Michelangelo (also known as Leo, Raph, Donnie and Mikey) The five siblings have a pretty awesome life. Well, except for when Leo, Raph and Donnie are bullying Mikey. Then Ella defends Mikey, saying that he can't help being the way he is. Like an actually understanding sibling would.
