This is the username I use on practically everything now, or some variation of it.
It comes from this site, actually. I was a massive fan of Pokémon Mystery Dungeon: Explorers of Time / Darkness, and I thought "Explorers of Destiny" would sound pretty awesome, so my username was The Explorer of Destiny. That was a bit lengthy, so I switched it to Explorer of Destiny and then simply DestinyExplorer. Recently, I ditched the Explorer part, and so if available it's Destiny, and if that's not available I'll probably go for Destiny X.
that bastard starcraft streamer i swear to god
