Roy

"Roy is a character from The Super Mario Bros. series. He is one of the 8 Koopalings, and also appears in Super Smash Bros. Wii U. He is generally well liked among the Blank Slate members.

The most notable exception is Sammy, who, likely as a result of taking too many Gameboys to the head, has somehow become convinced that he is a Fire Emblem character as well."

Roy is actually the main character of FE6.
