Caller The Gatecaller

Backstory
Caller, like all Gatekeepers, was born in an Advent Lab. The only difference is that she was deployed as part of a project called "A Better Advent" witch introduced a hand full of newer, more powerful Advent and Alien units.

After Caller was created and trained, she was deployed to the Advent Training Blacksite as an attempt to bump up the security there. The first alien she meet there was Keeper, they quickly got well acquainted with each other and even started somewhat of a... complicated relateishop... if you can even call it that.

Appearance
Caller is still a giant ball made of alloy and flesh, but the color of her armor is the main thing that separates her from the other Gatekeepers. Instead of a shiny white, Caller's armor is gray with purple decor.

Personality
Caller's personality is hothead and sometimes unpredictable. It's almost like Caller's personality got swapped with Keeper's over the course of her staying at the Blacksite.

Abilities
Caller is the most advanced Gatekeeper in terms of psionics, having more powerful base Gatekeeper abilities and even holding all the abilities of a Xcom Psi Op.

Relationships

 * Kayla and Jax: Caller does not trust Kayla at all because she's an Ex-Xcom op. Caller also thinks Jax is a complete moron for trying to hold a relationship with Kayla.
 * Keeper: As states before, Caller and Keeper holds a... interesting relationship, to say the least.
 * Caller also knows the Monsters from the Underground, but like Keeper, she knows very little about the AU war takeing place against Error and Nightmare Sans.
