Hi! I'm Isabella! but please call me Izzy, I'm the only sister to the turtles, but not the youngest, I am the oldest, but I'm not the leader, Leonardo is. Now as you've probably seen, I'm like all of my brothers, but I can handle myself so, I'm the oldest because I was found shortly after my family got mutated and I was older than the turtles. And it's a good thing I get along with all my brothers, and that's thanks to our Sensei. Master Splinter.
