It's a Crow, who's name is Sine (Yes named after the Mathematical term) You don't see many Avian characters, so here is one.

---Profile---
Name: Sine
Age: Less than one month
Species: Crow/???

---Bio---
Sine along with two others were created by none other than Seath, his main purpose as well as the other two creatures is to do Seath's dirty work, his main job is spying, having the ability to hide within other peoples shadows.

Sine is remarkably intelligent, and because of this is usually the one to formulate plans of attacks, assist Seath with "experiments" as well as other tasks that require his vast intelligence.

His common Quote is "My IQ is higher than yours, your argument is irrelevant."

Like any other Crow, he still has a fascination for shiny objects and hordes them away. He also has a love for fizzy Drinks, despite being physically unable to burp.

---Personality---
Sine is rather arrogant due to his intelligence and often will use his intellect to undermine others, provided he can actually out-smart them.

Sine on a whole lacks social skills, and has no desire to improve on them, he is only interested in hanging about those who are as smart or smarter than he is (though he'll never admit that.) Only because he thinks that everyone else "makes his brain hurt from their stupidity" Despite him also having moments of complete idiocy himself.

Despite being one of the bad guys, he is kind hearted, dislikes violence, but usually hides this side to him, considering these qualities as being weak.
