That Nazo
It is quite fascinating to realize that a character became so popular despite only appearing for like one second. I especially liked how well the stock voices synched well. I think this imitated "Dragonball Z" even more than the "Super Mario Bros Z" series. It helps that you know you to give the characters depth without the use of sprites. Nazo works great as a villian too, especially his distinctive voice. The effects are really the highlight, especially as you know how to show things like laser blasts.
