This is Juniper, a character brought into the world through the collaborative efforts of myself and an old friend. She was initially conceived as an inter-dimensional bounty hunter and would have starred in a crossover between his characters and my own, but sadly we both lacked the time and know-how to make it a reality at the time, leaving the project abandoned and me with sole ownership of Juniper.

A lot has changed since her inception. She retains the theme of cross-dimensional travel, but now Juniper acts as the scout for a small group of multiversal vigilantes known as the Legion, who operate from an area between the six universes called the Mind. From their headquarters, which they call the Mind Palace, they observe the connections between universes and take it upon themselves to combat any hostile action from one universe against another. Juniper herself acts as the reconnaissance for the Legion, gathering intel on potential threats from inside each universe when it is required.
There is no longer a bulky travel device on her wrist, but a glowing artefact on her left hand: a crystalline device known as a Mind Shard, which holds a small amount of energy from each universe and is powerful enough to manipulate reality, albeit on a restricted scale. Juniper uses this Mind Shard to create portals between universes for her to travel through as well as manifest ammunition into her guns.
