Superboy is often involved. His strength and somewhat volatile nature can make for interesting scenarios when he's under mind control. He could be made to use his powers against his friends, and it would be a struggle for the others to stop him without seriously harming him.
Robin is also frequently in these types of fanfiction. His intelligence and leadership skills can be manipulated.

Darth Vader is often a character in such fanfiction. His already powerful presence and connection to the dark side make him a prime candidate for either using mind control or being the target of it. Another common character is Luke Skywalker. Given his strong will and Force - sensitivity, fanfic writers like to explore scenarios where his mind is either controlled or he has to resist mind control.
Nami could also be a common character. Her intelligence and resourcefulness could be used in different ways when dealing with mind control. Maybe she's the one trying to break the mind control spell on others, or perhaps she's the one who gets mind - controlled and the crew has to save her. There are many possibilities.
