Deuce and Ace

The Ace and Two of Hearts - The Heart Kingdom's top soldiers

Deuce

Deuce is second in command of the Queen of Hearts' army.

He is mild mannered and well organized, which often leads the queen to send him on missions, rather than the true army commander, Ace.
Alice finds him boring, and often tries getting him to let loose a little.

The kingdom is aware of the Queen's favoritism towards him, though Deuce himself is unaware, and simply carries out his orders as a humble soldier.

He, like most citizens, is under the queen's spell. Though she does not have to assert orders over him, thanks to his honest and dutiful loyalty.

Deuce's common magic is speed. He can move faster than even the White Rabbit when using this magic.

His primary magic is indestructible sword. It is as it sounds- he can make his sword indestructible. It also becomes sharper and stronger.

Notable Detail: The back of his uniform has an ornate two of hearts pattern on it (the number 2, and two hearts, placed as they would be on a card).
He keeps freshly painted roses on his sheath because he often stands guard in the queen's court, and wants to properly represent the heart kingdom at all times.

Ace

As the Ace of Hearts, she's the head soldier to the queen's army, as well as the executioner.

Her violent and chaotic nature has only ever been reigned in by the Queen of Hearts and the White Rabbit. It was also somewhat reigned in by Alice, only because Ace respected Alice's lack of fear towards her.

Ace, unlike most of the Heart Kingdom, is aware of the queen's mind control. Still, she is under the spell and powerless to control it. Though curiously, she finds it entertaining, seeing it as a challenge to overcome. Thankfully, she has yet to do so.

Her duel sided weapon serves two purposes. The ax is for carrying out the queen's orders. The hammer is for her personal use.

Her common magic is explosive manipulation. She can touch an ordinary object and turn it into an explosive that will detonate upon its next touch. The “grenades” on her belt aren't actually grenades- until she uses her magic on them.

Her primary magic is berserk mode. Her strength increases to monstrous levels, and she becomes virtually indestructible. Only two things are known to be able to stop her rampages in this form; the queen's mind control, or the accomplishment of whatever task she'd set out to do.

Notable Detail: The back of her jacket has an ornate Ace of Hearts pattern on it (Two As and a large heart, placed as they would be on a card).
