Lycandroog; Copurnicus.

Seven foot from feet to head, not counting ears. Primary set of eyes see in only black and white, the secondary set see temperature. The jewel on their head is used for intraspecies telepathy, the veins around it in Copurnicus’ case indicates he’s had it modified to use as a cloaking device as well.
Lycandroogs are a gentle giant species of the planet Sirri (Sear-EYE) located in the Spurn Galaxy, they are entirely non-hostile.
Copurnicus is an ambassador of his planet and is also an upstart physician on his homeworld. He was raised by his mother while his father worked in interplanetary peace relations before getting assassinated by a hostile race mercenary.

In other timelines, he’s the last of his species.
