Deciding on how to tell about my first OC.

Ok, I been giving it some thought (also I will still pop back on the site to check my mail, feed, and my notifications and re-read a few stories) about my first OC, which in both of my stories have a mention about him, I do have one story that shows off his powers and what he does but It everypony in it will be a anthro, but I have been thinking of one where they are a pony, but it would also involve his army he controls and a few will get what the army is, some not, but I will say this. I am quite afraid of him due to him being almost unstoppable but not overly so, and like the Princesses, he is a very long lived person. The anthro one will show his power off, while the other will also show his power but also his physical strengths and skill.
