Dragon, not lizard - I don't do that tongue thing
Mulan's Mushu might not do that tongue thing, but Skyward Sword villain Ghirahim sure does!
The vain villain joins the fray in a rather interesting trailer, which shows off his swordplay, diamond animations, and super-powers. In addition to his fancy footwork and one-handed sword techniques, Ghirahim can transform into his "true form," which allows him access to more damage and faster speed.
While he wouldn't be my first choice he does look pretty fun.
