Queen of Hearts (Overwatch fan character)

Real Name: Morgan O'Brien (nee Oxton), Age: 77
Occupation: Professor
Base of Operations: Dublin, Ireland
Affiliation: University of Dublin, Overwatch (formerly), Talon (secretly)
“My my, deary. Have some tea."

Prior to her career as a professor at the University of Dublin, Dr. O'Brien was one of the world's leading scientists in the fields of combustion, thermodynamics and metallurgy. She came to worldwide fame when she spearheaded the development of a revolutionary propulsion system that allowed the creation of the Horizon space program, which she heavily took part in.
However, science and engineering weren't the only passions that O'Brien harboured. Having kept herself in excellent physical shape, the terrorist organization Talon made contact with her and recruited her as a mole within the scientific community, the Horizon space program, and later, a spy within Overwatch.
While she rarely took part in any of Overwatch's field operations, she was able to provide vital information to Talon and their allies, allowing them to incite the protests against Overwatch and the organization's fall, especially once the Blackwatch sub-division was exposed.
After deposing Overwatch, she rose through the ranks of Talon, becoming one of its commanding officers, dubbed the "Queen of Hearts", after the character from Lewis Carroll's story of Alice in Wonderland. The duality of the vicious personality of the Queen being plastered in the symbol of love appealed to her, or so the rumour goes.
With nobody knowing what exactly her motives are, or that she is living this dual life of kindhearted, caring old scientist and deadly assassin, the Queen of Hearts is one of the most dangerous women in the world.

Queen of Hearts Overview
Role: Defense
A gun hidden in her parasol and a chair armed to the brim with weapons make Morgan O'Brien a formidable opponent. She excels at disrupting enemies, which makes her a valuable asset on any team.

Abilities:
Passive: Throne of Hearts - The Queen of Hearts has created this floating chair to accomodate her problematic back, giving her much needed mobility. The chair is equipped with light thrusters that allow her to hover for a short time after having initiated a "jump".
Left Mouse: Parasol Gun - Morgan fires a short burst of bullets out of the tip of her parasol.
Right Mouse: Parasol Barrier - As her parasol is lined with light titanium plating, opening it up allows her to reduce incoming damage from projectile weapons. However, if the parasol rips, it cannot be used in this way for a short while.
Left Shift: The Comfy Chairblast - Leaning back and activating the thrusters on the bottom of her chair allows Morgan to create a blow that will knock back nearby enemies and deal slight damage to them thanks to the flames.
E: Russell's Teabomb - Having been an expert on thermodynamics, the Queen of Hearts of course has learned how to make the perfect tea. Only that her tea is laced with chemicals that make the thrown pot of tea explosive, dealing damage. The resulting puddle stays on the ground for a few moments and any enemy who steps on it slips across the puddle, taking away their balance and thus their ability to aim as long as they are sliding on it.
Q - Ultimate: Jabberwock - Inside of her chair, Morgan has two robotic grappling arms, that allow to grab an enemy and hurl them into a direction of her choosing. If she decides to use that enemy as a projectile against her enemies, it will deal massive damage and knock them back. If used in such a fashion, the thrown enemy will take 50% of that damage as they land.
