Their longest standing rival has been cross town Cleveland Hill High School which is the closest geographically to Maryvale's main campus.

Maryvale's first widely known mascot was the Peanuts character Snoopy, depicted in his World War I goggles and pilot's hat flying after the Red Baron.

Due to its proximity to Buffalo Niagara International Airport (BUF/KBUF) and industries such as Bell Aerospace, Curtis Wright (P-40) and Calspan, Maryvale adopted its title as the Flyers.

However Loyola College Prep in Shreveport, La is now the only school in the nation to legally have Snoopy as a World War I pilot as a mascot.

Their boys’ soccer team also won a section title in 2010, defeating large school Sweet Home in a shootout.
