Lore
Wendy O' Koopa is one of the members of the Koopalings. She's the only female among her siblings, and one of the youngest too. Her family is unknown, but she was adopted by Bowser at a young age. Since she was the only female Koopa within her siblings, Bowser mainly looked after her to make sure she wouldn't feel awkward around her siblings, this eventually led her to be more spoiled, thinking she's superior over others. But she's also taught that feeling compassion over other Koopas is necessary to grow as a better Koopa. This lowered his spoiledness as she grew up, but she was still spoiled regardless.

When she came into a proper age, she was assigned to Water Land, like her siblings did in other kingdoms, to control them. Of course, being the only potential queen among her brethren, she was really spoiled and was forcing others to bring her what she wants. But her days of getting what she wanted were ceased with two heroes ending her reign. She tried again, as she used dirty tricks, combined fashion, wits and magic in various ways: Like summoning fish, using ice skates and her signature ability with magic: Casting bouncy rings. But like her siblings, she had no such luck defeating their adversaries, but she tried again and again, hoping she'd stop her enemies in their tracks.

But as being young, she is still needing knowledge and skill improvements to grow stronger and wiser as a Koopa. She needs more time.
