There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

There are also certain amplifier configurations that need PNP units. Like an NPN transistor, a PNP can operate in saturation, linear operation, reverse active, or it can be cut off.
