This is my crux character, Axon.

He actually is somewhat glitchy despite being a physical being, which is a result of an accident he had experimenting with cross-dimensional travel, which is also the cause of his partial insanity. Despite this, he still manages to keep a sane side.

If anyone wants to hear his backstory in greater detail just let me know, and I'll either tell you directly or post it publicly. I'll probably end up posting the whole thing sooner or later, once I find out how to word it decently.
