Dr. Coyle is a scientist wearing a large metallic suit, with her design being electricity-based. Her ARMS are made of copper with coils rotating around them, referencing the concept of electromagnetic induction. She has green eyes, green hair which covers her right eye, yellow eyebrows and eyelashes, purple lipstick, and a purple mask. Her outfit consists of a black and green suit with a green top with her logo on it, a black high collar, a zipper and a belt, and grey tights, as well as matching black and green stiletto boots with green soles, and black fingerless gloves with studs and her logo on them, as well as green painted nails. Other outfits include a turtle neck shirt with a skeleton pin near the top along with a lab coat and glasses, and a dress-like lab coat with a black pantyhose and green high heels with black soles.
"She's the director of ARMS Laboratories, and a certified genius. Fascinated with ARMS since she was a young girl, Dr. Coyle decided early on to devote her entire life to ARMS research. Her plans for this research are not necessarily nefarious... She simply wants to be the most powerful ARMS fighter of all time...even if that means subjecting herself to her own experiments. But all her pain and hard work will be worth it if she wins the ARMS Grand Prix!" —Official description
Uniquely, Dr. Coyle does not have a jump. Instead, she levitates at all times and is able to increase her height with the jump button. This permits her to dash and guard at any height. She will be registered as being on the "ground" at any altitude; because of this, some weapons such as the Scorpio or Funchuk will always move out in the mode/form they are in when launched in the ground. In addition, she can briefly activate an additional ARM by charging for a long period of time. The ARM appears on a random shoulder of Dr. Coyle and matches the ARM immediately below it. Furthermore, she can temporarily disappear while moving freely, an ability activated by holding guard or getting up after being knocked down.

Grand Prix Ending
- She is the oldest known female fighter, at 48 years old. The second oldest is Twintelle at 26.
- Her name is a play on "coil," which her ARMS are made of.
- She is the creator of Hedlok, Springtron, and Helix, as well as being responsible for Master Mummy's reanimation.
- She didn't gain her ARMS naturally, but instead experimented on herself to gain the ARMS ability and succeeded.
- She's the only ARMS fighter to have unique dialogue when fighting other ARMS characters.
- Her victory quote after defeating Kid Cobra implies she has a dislike or fear of snakes.
- She can, in some cases, be seen as the opposite to Mechanica.
- Both are technically minded women who engineer themselves the ability to use ARMS.
- Mechanica is the youngest female fighter, utilizing a fighter suit made of scrapyard technology. Dr. Coyle is the oldest, using advanced technology to grant herself the ARMS ability.
- They are both admirers of ARMS, however Dr. Coyle's investment borders on "obsession".
- Mechanica is a fan of Ribbon Girl. Conversely, Dr. Coyle has a low opinion of Ribbon Girl, as she believes her pop singer occupation is a waste of time that would be better spent honing her ARMS talents.
- She is most likely the one who reportedly stole blueprints from Mechanica to create Springtron.
