And by brief I mean literal seconds. The above video shows most if not all the Amiibo costumes Mario can wear in Super Mario Maker. Mega Man pops in at the 1:19 mark and hops around a bit. He's so tiny!
For the uninitiated, the costume can only be used in 8-bit Super Mario Bros. stages. No Buster or anything fancy like that - it's a skin. You can unlock it with a Mega Man Amiibo.
Super Mario Maker launches in North America on September 11th.
