most Op but underrated character in anime?

this thread is for the most op anime character but at the same time underrated.

for me it would either have to be Ren from shaman king or Ageha from psyren.

@rikuyamaha: The Guyver has some rather overpowered abilities but there are definitely trade offs.

Aleister crowley in to aru.

Underrated as in not well known?

Saiki from the Disastrous life of Saiki K

He's a psychic who pretty much bends reality to his will, his powers are almost limitless but he does have odd restrictions and cool down times for some of them.

Dragon Ball being underrated? You fanboys never quit LMAO.
