15 Transforming Bosses That Made Life Hell

Master Core – Super Smash Bros. Wii U

In terms of final bosses in the Smash Bros series, Master Core in Super Smash Bro. Wii U is hard to top. If you play on the highest difficulty, you’ll go from fighting Master Hand and Crazy Hand to a dark humanoid mass with projectiles for days. Deal enough damage and it turns into a tailed beast that calls down lightning. Next, a squad of swords and then a shadow version of the character you’re playing. And if you somehow best all of that, you then face the Master Fortress, a maze with a core that must be damaged multiple times. And then finally, finally you face the Core on its defenseless lonesome and defeat it for the win.
