Shadow Swingstress

The Shadow Swingstress is a character in Mario Tennis: Power Tour who follows the player's progress in the story mode of the game. She's an unranked junior player who's thrilled to have another unranked junior in her class, and initially assumes she can catch up with Clay and Ace, then sees their talent level and begins to ask them for advice. Her real name is unknown but resembles the appearance of Nina. The title "Shadow Swingstress" comes from a nickname she got from other junior players. Her doubles partner is another unnamed shadow swinger, only known as the "Shadow Swing King".

Other people in the junior class have made comments about their level of play. Sylvia and Sasha comment when playing against them that they're easy opponents. She seems focused, but without direction. It's implied that Clay and Ace serve as surrogate coaches once they hit varsity, and give her and her partner motivation to try to become better players.

"What the fuck did you just fucking say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you out with precision the likes of which has never been seen before on this Earth, mark my words. You think you can get away with saying shit to me over the Internet? Think again, fucker. As we speak I am contacting my network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your tongue. You didn’t, and now you’re paying the price, you goddamn idiot. I will shit all over you and you will drown in it. You’re fucking dead, kiddo."
