Kai

Kai is a sixteen year old feral dragon, and Ian's Sentinel partner.

Appearance
Kai, like Ian, is small for his race, only measuring five feet seven inches from tail to wither, though his neck and head add more than another foot. Kai is of average build for a dragon; his scales are coloured deep crimson, and he has a single pair of straight horns protruding from the back of his skull, along with neck, back and tail spikes.

Background
Left as a hatchling on Earth while his parents fought, and later died, in a Terran war, Kai was adopted by someone who he refers to only as 'Old Lady Kara', whose reasons for both taking him in and keeping a dragon a secret remain unknown. Kara taught him to speak and how to act within society as best she could in Kai's early years, but upon her death from old age, Kai retreated to a mountainous cave and lived alone, hunting for himself and hiding from humans, as he had been told.

Kai encountered Ian when the latter was walking in the mountains near his cave; a bored, lonely Kai swooped down to snatch him up like prey as a joke, bringing the terrified human back to his cave. After eventually convincing Ian he wasn't going to kill him, Kai enjoyed his company before sadly telling Ian that he could leave. Upon Ian's refusal, Kai let the human stay in his cave, grateful to have a friend.

After hormone related incidents caused Kai to share his essence with Ian, a routine trip out of the cave turned into his human companion being attacked by wolves, which Kai was able to fight off. His emotional state caused his inate magic to heal the wounds Ian had obtained, while also alerting a tracker to their location.

Upon the tracker informing him he had to 'return' to his homeland, Kai refused to leave Ian behind, and was subsequently brought to Terra along with the human. Both were recruited into the Sentinel programme after showing the necessary level of aptitude.

Personality
Kai is extremely shy, due to his only other contact being with Kara, often only fully comfortable talking to Ian or having his companion answer questions for him. Ian's genuine concern for him, along with the human's decision to stay with him, causes Kai to bond with the human to an extremely powerful degree; strong enough for Kai to use magic through instinct, as well as pushing him to become as fierce as one might expect of a dragon.

It also appears that, when in a medic role, Kai is temporarily able to overcome his shyness, as shown by him treating Skylar's back.

Powers
Kai has a natural, powerful healing ability. He can also breathe fire, an inate talent of his race.
