Inky

Inky, also known as Aosuke in Japanese and nicknamed Bashful, is one of the four main ghosts in the [i]Pac-Man[/i] series. He is often depicted as a goofy and slow-headed ghost, not pursuing Pac-Man unless other ghosts are near. He is good friends with Blinky, Pinky, and Clyde. While originally one of the main antagonists in the first [i]Pac-Man[/i] arcade game, his role has changed to being an ally in recent iterations. Inky made an appearance in [i]Pac-Man and the Ghostly Adventures[/i]. Rather than an enemy of Pac, he (along with Blinky, Pinky and Clyde) act as Pac's allies. He seems to be the most sarcastic of the group, and may be the most intelligent member. Blinky seems to have a sort of rivalry with him as well. (Source: Pac-Man Wiki)
