Meh. I types it how I says it, plus Leo Prime has been messing with my head. But you know who I mean.
Although I do prefer Leo over Lio. Lio just sounds like they have made a typo. Although I'm guessing it works better in Jap.
Leo I like because it refers to the Zodiac sign for Lion, so I think it is more fitting. Kind of like how Big Convoy is a big dude
