The Rabbit Sapper was first revealed on May 4, 2014 once the Rat Assassin was unlocked on the Armello Kickstarter campaign. He himself was made available to backers once the $235,000 AUD stretch goal was reached.
 Sappers are combat engineers employed in a number of armies world-wide, with their primary duties being to build up or demolish structures, simultaneously advancing the movement of their own forces while impeding their enemies.
He's the youngest hero in the game.
