|“||You could have just sat quietly in your cell like good little prisoners… But noooo, you had to escape and make us chase after you. So inconsiderate.||„|
|“||Oh, hello. I'm Wendy, and I'm here because the Olympic Games deserve a dazzling, sassy heroine - and those two posers Peach and Daisy do NOT count! I'm the only young lady in the Koopalings, so I'm used to attention and press and all that. Kind of boring now, unfortunately. Ah, well. The life of a star...||„|
|“||My golden ring has you in its embrace. Your face is priceless!||„|
Wendy O. Koopa is the third youngest of the seven Koopalings and a recurring antagonist and boss in the Mario series of video games. She is also the only female member of the Koopalings.
She also makes an appearance in two Mario cartoons where she is known as Kootie Pie Koopa. She is also in a Japan-exclusive anime where she goes by her actual name.
Super Mario Bros. 3
Wendy is the third Koopaling to be fought. She is encountered on an airship in the water level. She fights differently than her brothers Larry and Morton, instead of shooting magic attacks, she creates energy rings that fly around the arena. Whenever she takes damage, she will create one more. She must be jumped on three times to defeat her. Once defeated, she runs off, leaving behind the wand she used to transform the king of Water Land.
Super Mario World
Wendy is the sixth Koopaling to be fought. Like Lemmy, she comes out of pipes to attack, with two decoys that look different in color from her. She must be jumped on three times to defeat her. Once defeated, she falls into the lava.
Mario & Luigi: Superstar Saga
Wendy somehow returns in Mario & Luigi: Superstar Saga, in Bowser's castle while Mario and Luigi are trying to get to Bowletta. Again, she is the sixth Koopaling to be fought. Once defeated, she apparently dies and vanishes like the others.
New Super Mario Bros. Wii
Once again, Wendy returned with the other Koopalings to kidnap Peach for Bowser. She is the fourth Koopaling to be fought, at a water level like in Super Mario Bros. 3. She fights in a similar style. She is fought twice. The second time, Kamek modifies the arena so that it occasionally fills up with water. Once defeated, Wendy fell over the edge. She survived, however, and was last seen after the credits alongside the other Koopalings, Bowser, and Bowser Jr., before Bowser's castle fell over and crushed them.
Mario Kart 8
Wendy and all of the other Koopalings made their first appearance as playable characters in Mario Kart 8. She and Larry are both in the lightweight class.
Super Smash Bros. Series
Wendy O. Koopa has been used as a alternate coustume for Bowser Jr in Super Smash Bros. For 3DS, Super Smash Bros. for Wii U, and Super Smash Bros. Ultimate.
Wendy has a pink shell, and a pink bow with white polka dots on her head. She also wears large round yellow bracelets and a red bead necklace. She also has big pink lips. She also has a padded stomach, she is the only Koopaling who wears shoes, the others are barefooted, that confirms that she has padded feet like her brothers.
- Wendy O. Koopa is named after the singer Wendy O. Williams.
