Mysterious Figure 

One of two secret bosses from the PSP game Kingdom Hearts: Birth by Sleep.

The Mysterious Figure fights with two glowing blades, similar in design and function to those of Xemnas. Alongside his regular attacks, the Mysterious Figure can also freeze and rewind time, make clones of himself, and cast several high level spells, such as Mega Flare and Meteor. The boss's most lethal attack is a jumping "lasso" move, which not only does significant damage, but almost always leaves the player open to a second, fatal hit immediately afterward. These attacks, combined with the Mysterious Figure's high speed and resilience, allow him to officially outclass Sephiroth as the hardest boss in the Kingdom Hearts series, and possibly the hardest in all of gaming history.

Those who can defeat the Mysterious Figure on the highest difficulty with all players will earn the right to call themselves a hardcore gamer.

Johnathan: Come on, come on, only 1 health bar left! I've got you now, you bastard, I've got you-

Mysterious Figure: (destroys player with Mega Flare)

Johnathan: That's...not...fair. WHY IS THIS BOSS SO F#@%ING CHEAP!!!
