Well Lizardon is certainly a great name. Charizard is one of my fav characters, as I've probably told you already xD. I think his reveal as a solo character in Sm4sh is actually my favorite character announcement so far, haha. Dragons 4 Sm4sh 4 life.
Also, I've grown fond of Charizard (my project M main) and I wanted to change my name to his to show my support someone else got his name (and failed to make use of it)
