Ten Facts About Sesshomaru
1. Lord Sesshomaru does not take orders from anyone. Even Naraku. Example quote: "It was Naraku's doing, and I refuse to play by his rules."
2. Sesshomaru is not going to admit that he cares about Rin (even though he totally does). Ever. If you kidnap her, he might come to save her. Maybe. If he doesn't have anything better to do. And if he's in the mood.
3. Sesshomaru is regarded by some, including Kagura, as the only demon capable of killing Naraku. I'm not completely sure I agree with that (see my next point), but it does speak volumes about his ability.
4. Despite trying on many many MANY occasions, Sesshomaru has never been able to kill Inuyasha. And Inuyasha is the only person/demon thus far to have seriously injured Sesshomaru. Twice. So what makes Naraku think he'll be able to succeed this time? Especially since the brothers seem to be on friendlier terms now that they worked together to defeat the panther demon, and since Inuyasha's red Tetsusaiga is really freakin' super-special-awesome strong.
5. Sesshomaru has been known to kill demons simply for not moving out of his way fast enough. If you dare to mess with anything of his, including Rin, he's probably going to kill you.
6. Lord Sesshomaru regards himself as the greatest demon in the history of ever who deigned to grace the earth with his presence. He sees everyone else as nothing more than dirt on the bottom of his shoe. This is both his greatest strength (it allows him to fight without fear or trepidation) and his greatest weakness (he frequently underestimates his opponents). It also means that he's not going to explain himself to anyone. Especially not Inuyasha.
7. Sesshomaru rarely shows any emotions, positive, negative, or otherwise. So if he looks angry or upset, watch out, And if he smiles, RUN.
8. Sesshomaru has never been truly defeated. He's even managed to get away from Inuyasha's attacks, including the Wind Scar, more than once. On top of his inherent awesome-ness, he also has Tokajin and the Tessaiga. So you'd be a fool to believe that you've killed him without actually seeing his dead body. And possible dismembering it for good measure.
9. Sesshomaru is not doomed, he is not weak and no matter what you may think, Naraku, you have not absorbed him into yourself. Please. Read the other facts and learn why this is so.
10. Sesshomaru's sword, Tessaiga, brings people back from the dead. So even if you kill Rin, that's not going to accomplish much.
Bonus: If Inuyasha and Sesshomaru could ever stop being male long enough to work together, they could totally take out Naraku.
P.S. Rin/Kohaku = Tru Luv!!! (Seriously though, they are ADORABLE together.)
