My Zed theory:
If Zed takes off his ask his mask, he's actually Talon. And if Talon takes his hood off... He's nocturne. And of course Nocturne (like all the other champions) is Teemo disguised.

Did you know that Shen doesn't truly teleport, but he stealths and another Shen takes his place?

Whoa whoa whoa. Let's take a closer look.
Zed. That's three letters. Remember that.
Talon. Five letters. 5 - 3 = 2.
Two items are in this equation.
2 x 2 = 4.
Teemo. Teemo is Satan. Satan's on fire.
Fire has four letters. 4 + 2 = 6.
Zed has three letters, so three 6's. 666.
What is that? 999 upside-down.
6.0 6.0 6.0
6 x 10 = 60.
There are 60 degrees in each angle of an equilateral triangle.

Back to Zed having three letters. So does eye.
