I apologize if this thread has made before, but I'm curious to hear how you came up with yours. Also, I think mine is pretty cool.
When I made mine, I went through all the boss names from Zelda: Link to the Past (my favourite game of all time) and all of them were already taken. Then I remembered Trinex, who seemed like a really cool boss. That was taken, but since he has 3 heads, I put 3 x's in the name. It also displays my love for pornography. 2 birds, 1 stone :D
