Ink sans

Ink!sans : In the long run, Ink!Sans is generally optimistic, has a sense of kindness, In the more serious side, he objectively tries to reason with anyone, and only follows who he finds his best friends. However, he has no soul, and relies heavily on emotion vials. If he stops taking the emotion vials for a certain period of time, he will lose all emotion that he once had and is unable to do any sort of action, as shown in Underverse 0.3 Part 2. This doesn't matter though, as Ink intended to not use his emotion vials for his plan to revive his friend. Overall, this proves him as being villainous and selfish without the "emotion vials".
