So ya, to sort of get my character idea down in more detail, the gist is-
God of survival and tenacity, came to represent paranoia and hording as well after the war. Originally was basically divine Bear Grylls, teaching or blessing the races of the world to survive the most extreme adversity possible, not via being big godlike beings just by being clever and willful. In the war he tried to remain fairly neutral unless challenged, but was crippled and mutilated in combat with either another god or powerful heroes. The near-death of a god of survival was an especially traumatizing event, and he went from a globe-trotting god who accepted all challenges to a paranoid shutin. The parts of him, physical and spiritual, which were lost in this transition eventually regrew like the limb of a starfish into a demigod who became his avatar in the mortal plane, an adventurous and wild figure who scares him even more than the other divines. I was thinking after more consideration he'd have a quite chimeric appearance befitting of his adaptable nature, with specific emphasis on insectoid traits (since bugs are feccin unkillable) and draconic/lizardlike traits (because personal preference). His people are basically kobolds, and in different parts of the world have adapted to be similar to many different kinds of kobolds across different fictions (ie some are lizardlike, some are goblin like, some are weird dog people, etc)
If anyone has any particular interest in their god/heroes being responsible for the mutilation I'm open to hearing so, or any other comments or questions on the idea before I write more up.
