Handsome Dragon
Borderlands 2 had its fair share of big, bad bosses, but in the Tiny Tina’s Assault on Dragon Keep expansion, you can find an honest-to-God unbeatable monster just outside the gate to Flamerock Refuge. While Tina narrates a game of Bunkers & Badasses, she’ll cause a dragon to appear out of nowhere to fight the Vault Hunters. Your weapons are utterly useless, and its special attack can instantly send your whole team into crisis mode. Thankfully, Tina soon calls off the Dragon and replaces it with a more reasonable, killable boss.
