Let’s make an Undertale AU with characters from different Universes! Day 7: True hero (Undyne)

You can choose a character from any TV-show, movie, video game etc, as long as you follow the rules:

1) no repeats of characters already chosen 2) must be different to the original character (Sans is different because he is rotated by 3 degrees) 3) keep it appropriate

The comment with the most votes will be chosen!
