Calvin (left), and Klein (right).
Together they are Orhtros, the guardian of the forest.

Calvin and Klein were originally two separate entities.
After destroying a forest with one of their usual fights, the forest's keeper cursed them to be one entity, with an extra pair of unsightly limbs, for as long as her forest hadn't grown back.
Now as one, they put aside their fighting to keep guard over her recuperating forest.
