This is a reference to "Avatar: The Last Airbender". Toph Beifong started a metal bending academy to teach the newly invented skill to anyone who wanted to learn. Her family crest is a flying boar, so it made sense that any sports team from her school would take that on as the mascot.
Future Industries is the premiere technology corporation in Republic City. Founded by Hiroshi Sato, and later operated by his daughter Asami, Future Industries produces everything from Satomobiles to Blimps and Biplanes.
Future Industries is also the sponsor of the Pro Bending team "The Fire Ferrets", of which Avatar Korra is a member.
