Road Roller Extreme, or R.R.E. for short, is a super robot in my mega crossover fanfic "Super Milestone Wars". It's a robot similar to Gokaioh from Kaizoku Sentai Gokaiger. R.R.E. can summon the greater powers of other super robots by inserting a Rider Card-like card into a Tensouder-like device located in the cockpit.
