The Traveler (Tales From the Borderlands)
Outside of a terrible final boss in the first game, Gearbox has always had a knack for creating fun boss battles. The final bosses are up there as some of the best of all-time, as The Warrior, Handsome Jack, and Troy were all superb.
It’s a different big bad in the series that features the best boss, though. That boss is The Traveler from Telltale’s Tales from the Borderlands saga.
After failing to take down The Traveler the first time, a final battle occurs between it and the Vault Hunters. Depending on the choices that were made throughout, a number of different unique characters can be chosen to fight in the final battle, taking their places in a Megazord-like Gortys.
You can argue all you want about the fact that the fight is really just button prompts, but the different variations, one-liners, and fan service that occurs throughout it are worth the price of admission.
