MararV is just a shortened version of my last name with my first name; I chose it because I'll only visit this site once, and I want to avoid having to guess who I am if I ever come back here.
In general, I use the nickname BanesWolf almost everywhere.
Since childhood, I've liked wolves, especially werewolves, but I couldn't come up with a nickname related to wolves that was original and not something like "Lonely Wolf, Ice Wolf, Red Wolf..." I couldn't think of anything for a long time, but then I stumbled upon the band Wolfsbane online. I almost took that as my nickname, but I didn't like the translation (Wolfsbane, although I'm not sure about that; in the Marvel universe, it has exactly that meaning), so I just switched the words around, creating BanesWolf, which translates to "poisonous wolf."
That's how it happened.
