Okay, so referring to your post in the OOC, here are some of my responses. :3
Alright, so what does extraplanar entitle? Do I need to change anything about the character stat-wise or in any other way structurally?
I probably should have gone into how his body works more in my SU. XD;
Anyway, his current incarnation is indeed, in a sense, ageless. His appearance is not a matter of age, but health. The reason he takes the appearance he does is because it's to represent a man at his peak of health and activity, Age is a matter of association to the examiner of his body. When his health is low, his form changes to represent his poor health, and yes, it is possible for him to die. His form now may be immortal in a sense that if unaffected, he will live forever and retain his appearance, however, the similarity and formulaic structure of his body does entail death if he is attacked. That's why is he is attacked, he must fight back.
And statistics did throw me a bit. So taking in account of my abilities and character, could you possibly assist me in this? X3;
Hope this helps. I'll go add my new info into my SU.
