Well since special eye abilities are sort of cliche anime/manga... Which eye technique is the best in battle. Assuming all the users have the same physical and mental abilities. May contain spoilers for Blackcat and Basilisk (abilities not immediately revealed). Byakugan - Naruto - Sees 360 around the user for a wide range and see a person's chakra flow and points. Evil Eye - Getbackers - Traps a person into an illusion insantly for a minute. Gennosuke/Hyoma's Eye Technique - (Don't think it has a name) - Basilisk - Instantly forces anyone who looks into the person's eyes to commit suicide. Whatever technique they are using is immediately turned against them. Glaspar Eye - Black Cat - Sees into the future to a certain extent but drains the user. Also able to stop time for at least 5 seconds without any strain or taking up much energy. Ryuugan - Tenjou Tenge - Sees into the past and the future, predict a person's move to a great extent, read a persons thoughts, along with the ability to project very realistic illusions. Sharingan - Naruto - Predicts a person's movements to a small extent. Mangeyko Sharingan allows the person the ability to trap a person into the illusion for 72+ hours and reduce them to ashes with a glare. The affects are nearly instant but requires time to activate and it takes a heavy toll on the user.
