mystevious 

A combination of mystery and devious. Used to describe a person whose actions and plans are both mysterious and devious, especially as it relates to business matters.

"Rick's corporate organization is so complex that the only word I can use to describe both it and him is mystevious.

Here's the way it appears to work: he owns all of Acme 1 Inc. in which he has invested $25,000. Acme 1 owns 51% of Acme 2 which has outside investors that invest $25,000 less a dollar in Acme 2. Acme 2 then invests all of the proceeds in Acme 3 in return for 51% of Acme 3. Again Acme 3 has outside investors that put in cash equal to the amount Acme 2 has invested less a dollar.

By the time Rick has incorporated Acme 12, he controls (absolutely) a company that has $51,197,953.00 of cash on hand with an initial investment of just $25k. And it's all perfectly legal to boot."

Mysterious Figure 

The biggest dick in all gaming history.

He's an optional boss in kingdom hearts, birth by sleep. He has 2 lightning energy dagger type weapons and he can cast pretty much all the strongest spells such as meteor, megaflare, death, and all of his melee combos bring you to 1hp almost, he also turns invisible at half health and you can no longer see or lock on to him or see where he's coming from, he can make multiple clones of himself that can all do the same attacks and he has an attack that erases all of your special attacks.

Also if you start doing a moderate amount of damage to him he will either put up a temporary shield that makes any damage heal him or he will stop time, reverse it, teleport behind you, begin an attack, and then unfreeze time again.

"Oh hey its Mysterious figure, maybe i should fight hi-"
*1hp*
*dead*
"What just happened?!"
