Sue

Sue (Japanese: スー Suu) is one of the few female ghosts seen in the Pac-Man series. She is not to be confused with the arcade owner in Pac-Man World 2 with the same name.

Ms. Pac-Man
Sue first appeared alongside Blinky, Pinky, and Inky in the game Ms. Pac-Man. She was identical to Clyde from the original Pac-Man, and moved in the same random patterns. The reason for the name change from Clyde to Sue was due to Ms. Pac-Man having her own arch-enemy. This is similar to the orange ghost in Pac-Man Jr., named Tim.

Pac-Land

Based on the Pac-Man animated series, Pac-Land features Sue as the only female Ghost Monster (Pinky is male in the cartoon). She does not ride a vehicle and always chases Pac-Man, like Blinky does in the traditional games. Sue travels at a slow pace (in fact, Sue is the slowest ghost in this game), but when time starts to run out, she begins to charge at Pacman mercilessly.

Pac-Mania
Carrying over her aggressive persona from Pac-Land, Sue behaves as Blinky typically would, but never enters "scatter" mode (she momentarily changes direction with the other ghosts, but always uses Pac-Man as her target). However, Sue moves at the same speed as Pinky in this game, which is pretty fast compared to the other ghosts, but slightly slower than Blinky (who always moves the fastest).

Pac-Attack
In one of the versions of this game, Sue can appear as one of the ghosts dropped with a block. She is also the primary ghost dropped for the 2nd player in "VS Mode"
