Agent Cobalt

Agent Cobalt is the eponymous main protagonist of Cobalt. They are a Metalface MK-1, sent to the planet Trunkopia to investigate the disappearance of the humans 50 years prior to the events of the game. They are chosen for the mission by Borealis on the basis of being "the best". They do not know who they are, as they had received a memory wipe when they became a Metalface.

Agent Cobalt is genderless.

Personality
Agent Cobalt's personality is shown in the Story Mode. In it, their overall personality can be somewhat changed by player input, but in cutscenes with no player input (Such as conversations with The Seed and the reports they write after each chapter), they tell jokes concerning the deaths of enemies (and prisoners), though they also seem to display care for certain characters (to an extent).
