Joe Yimbo is the body guard of James MacCready
and does his job by using the sword like projections that come from his body. He originally only had two long claws that extended from his wrist. No mention was ever made about how he used the bathroom. He can use his claws to cut through most things even his enemy the Ghost
even while she is intangible. He tried to kill Ghost's sister Margo Cameron
but was unsuccessful and stabbed himself with his own hands as Margo was turned into a ghostlike state by Ghost.
He later became embroiled with Snake
over Dr. October
. He thought Snake killed Dr. October whom he worked for and with whom he also fell in love with.
