Writing in first person

So, I've never actually written a story using first person, and I'm curious to try it. So I want to write one to try it out.

I've been thinking about writing from the point of view of Ascaris (I'm torn between the name Ascaris and Dracun, still deciding) who is Scollex's brother (they're both named after something relating to parasitic worms). He hasn't appeared yet before, but I want to add more antagonists to my story universe thingy. So far I have Glen, which is an enemy mainly to Kage (however he's also hostile towards the others due to them being killers and stuff), and Scollex, who is also an enemy to Kage (but he might get along with Zehnder or something). Ascaris might be a little different when it comes to motives though. Won't spoil anything.

Anyway, this should be an interesting thing for me, might write it today, but chances are slim 'cause I don't think I'll have time to.

I want to know which name you guys think is better, Ascaris or Dracun.
