The root of the username goes way beyond its' creation but I don't really remember where that started. That said, my username proper is a pun on tuna and either the town of Thun in Switzerland or thunder (which is more likely, since Rio de Janeiro, my hometown, is infamous for its' storms). There might be an old Mortal Kombat OC or a Sonic OC related to this though, I'll see if I can remember it properly one day.
