Masuo Ōkama (大鎌 増夫, Ōkama Masuo), or Muscle Ōkama (大鎌 マッスル, Ōkama Masūru), the name given to him by Kyousuke Hyoubu, is an Esper of P.A.N.D.R.A.. Later in the series, he becomes the Roviet Ambassador to Japan, under the name Muscle Ōkamanov (マスール オカマノフ, Masūru Ōkamanofu), another name Hyoubu gave him.


Muscle is a tall man with tan skin. He usually wears homo-sexual themed clothing, though he sometimes wears a suit to keep up appearances when posing as an ambassador.


He has a very laid back personality. He is also openly gay, a fact which he makes abundantly clear all throughout the series. Many years prior to the series Muscle was seen being somewhat of a father figure to many of the P.A.N.D.R.A. members.


Not much is known about Muscle's past, but it has been shown that he has been with P.A.N.D.R.A for at least 10 years. He looked relatively the same 10 years ago.



He can shoot beams from between his legs which turn living beings (or maybe just humans) into stone (or some kind of iron).
