Myoga

Myoga the flea demon, was once the retainer to Inu-Yasha and Sessho-maru's father, a canine god. After the death of their father, Myoga was told to guard the Tetsusaiga, a powerful sword that belonged to the god. When Sessho-maru began searching for it, Myoga went in search of Inu-Yasha to ensure it did not fall into the wrong hands. After saving the sword, Myoga stuck around and has continued to travel with Inu-Yasha and serve him faithfully. Unlike Sessho-maru's servant, Jaken, Myoga rarely gets involved in any sort of physical battles. He often gets crushed by someone assuming he is a regular bug. One of the few abilities he has ever shown, is when he saved Inu-Yasha's life by sucking a Spider Head's venom from his system. Myoga also is shown to have a great knowledge of other types of youkai. He is often able to identify an unknown demon and provide some background infomation on them to his companions. But most importantly Myoga is a huge chicken every time something bad is about to happen he runs away and then as soon as the fight's over he'll come back with some excuse at why he diserted his friends. Inu-Yasha isn't very sympathetic twords fear so he makes Myoga pay for his little spazem-attacts.
