This design is a play on the “RUN DMC,” logo. I extended the red boarder into the #5 and replaced the text with “RUN AWAY” to form a logo for The Runaway Five. I also added in the katakana: トンズラブラーザズ which reads Tonzura Brothers, Tonzura meaning Runaway. (This is the original name referred to in the Japanese version of Mother 2)
I also have a variations on this logo in the form of posters.
