Sesshomaru
Name Information:
His name is often spelled Sesshoumaru. It means "destruction man".
Character Description:
Sesshomaru is the older brother of Inuyasha. They share the same father but while Inuyasha's mother was human (making him a half demon), Sesshomaru's mother was not, and he is a full demon. No information has been given on Sesshomaru's mother.
Like his brother, Sesshomaru is an inu youkai (dog demon). In his regular form, he has several poison attacks including the Dokkasou (toxic flower claw) and the Dokumukou (paralyzing poison). He is also extremely fast.
In his more demonic form, Sesshomaru transforms into a giant dog who breathes Jakimukou (paralyzing miasma).
Sesshomaru and Inuyasha have a strange relationship. Sesshomaru feels superior because he is a full demon and does not like the fact that Inuyasha cares for humans, but he does not seem to realize that his father must have cared for humans too, at least somewhat.
The brothers each received a sword forged by Totosai from their father's fangs, but Sesshomaru is angry that he was given the healing Tenseiga while Inuyasha was given the Tetsusaiga. Despite his claims, it was obviously meant to be that way, since only a half-demon can hold the Tetsusaiga, and it feeds off the need to protect humans.
Sesshomaru also had another sword made - Toukijin. It was created by Kaikinbou, a former apprentice of Totosai, from a fang of the demon that was able to break the Tetsusaiga.
When Sesshomaru comes upon the human child Rin, he begins to take care of her, and even guards her. He does not come right out and say it, but it seems he is developing the ability to care for humans, however slight.
Sesshomaru often speaks of wishing to kill Inuyasha, but during the (many) chances he has, he prefers to wait. He may or may not want to fully go through with it, despite what he says.
