! Got M!necratft for the f!rst t!me

Hello. 
! have just acqu!red M!necraft and ! can't th!nk of my username. A lot of the t!me ! use usernames related to one of my 10 names (Atlas, Comet, Hyde, Wonder, Er!s, Theros, Syre, Floren, !carus) but they don't seem, spunky enough for a M!necraft username. 

Anyone have any !deas?
