this isn't what i wanted!

There are a series of robot toys called "Kore jyanai Robo!" ("This isn't what I wanted Robot!")
You've got the female, the enemy, and the hero.
According to the explanation:

How many times has the magic of Christmas morning been broken by a child tearing open a wrapped present only to explain "This isn't what I wanted!"
But life ain't so simple that you can just get whatever you want without taking any risk. Isn't it worth teaching that in order to get what you want, you have to be willing to earn it, to sacrifice? This toy teaches the harshness of reality by inflicting such trauma with its blatant not-wantedness that any child will surely learn this lesson.
Consider it an educational toy.

Absolute genius. Collect the whole set!
