Lightning Cloud !! Why name him or her after one char when you can name it after two chars xD
Anyway I usually tend to like the names of the Resident Evil series seeing as they arent to wierd and are linked to awesome characters like Albert Wesker, Claire and Chris Redfield , Jill Valentine , Leon S. Kennedy :O
Just to name a few :D (http:/*/en.wikipedia.org/wiki/List_of_Resident_Evil_characters all the names here !)
Have fun with the selection!
