10 Video Game Bosses Who Can Secretly Join Your Team

10. Cicero - The Elder Scrolls V: Skyrim

The Dark Brotherhood questline from Skyrim is full of treachery, some of which happens within the very organization you're working for.

One of the earliest conflicts happens between the Brotherhood and their somewhat unstable (to put it lightly) newcomer from Cyrodiil, Cicero.

The dastardly jester is, surprisingly enough, a staunch traditionalist and his disagreement with Astrid, who tends to ignore most of the old rules, eventually causes him to attack the other Brotherhood members before retreating to the city of Dawnstar.

It's here that you have to track him down and take revenge for his treason. However, you can also do the opposite of what an assassin should do and spare him - allowing Cicero to make a sudden reappearance at the end of the quest.

If you choose to let Cicero live, the merry serial killer will return after the Brotherhood is rebuilt and offer to join you as a faithful follower.

The clown is a wholly unique companion, with custom gear, a unique fighting style and voice lines, making him a truly one-of-a-kind buddy that you absolutely need to preserve - especially since at the end of the Brotherhood questline, there aren't that many familiar faces left in your psychopathic family.
