his eye power is "emperor eye" which can see even the smallest details of your opponent's movements(breathing, heartbeat, sweat, muscle contractions, etc.) allowing you to predict your opponent's next move.
Does Peggy J.Crawford's Millennium/Sennan Eye count? It's (Main) Special power is seeing your opponents cards in their hand oh and also it can take souls..it's really interesting in my opinion,though I kind of felt bad for Yugi's Grandfather,Mr.Kaiba and Mokuba in those episodes as well as Yugi.
dont forget PAIN from naruto,
his eyes are called reininggan,,they say that its the most powerful eye power from the anime naruto...
but I really dont have an idea for what it can do 'cause I'm not a fan of pain.
Here is an awesome eye ability own by Kano Shuuya from the anime Mekaku City Actors :D. The eye is called "Deceiving eyes" which deceives the eyes of others and make people around him perceive him differently. Example may be like you look at him holding a gun while he is actually holding nothing but a wooden stick.
His Shin no Ippō allows him to freeze enemies and paralyze the target even to the point where he can make there lungs stop, and he can also use it on himself to make himself believe he is invincible and greatly increase his power
