One of my videos had a character I called "Tav", Tav was the Gasoline of another universe, but Tav was actually created earlier (created a year ago), originally named "Tax"(created as a satire), and then I changed her design a little bit. At first I was going to let Tav be my sona, but for some reason I created Gaskoyig based on Tav's design and appointed her as my sona

And Gasoline and Tav's full name, :Tavilarovko Gaskoyig(they're essentially the same person so they have the same name but different nicknames).
