Well what makes the most sense psychologically is that each 'personality' has things they deal with better, and it's not that there's a specific trigger, per se. The theory behind DID is that the personality splits itself to deal with problems that the conscious personality can't take. Maybe one personality is nicer, more sociable and easily hurt, better able to perform everyday tasks, while another has a tougher skin and able to power through tough situations to protect themselves, but has trouble in social situations. So depending on the situation, when one personality starts to get upset or uncomfortable, that's the cue for the other one to 'take over'.

SPATULA, Supporters of Page Altering To Urgently Lead to Amelioration (supports not going through TRS for tweaks and minor improvements.)From what I understand with brief contact with the literature, one personality is normal, and the others are coping mechanisms for various levels and types of stress. The alternate personalities basically exist to defend the main one. (Though I should note that often they're not necessarily aware of each other.)
As such, The Incredible Hulk is cliche, but not entirely wrong.
Nous restons ici.Touko in Kara No Kyokai used her glasses to create split personalities on intention.
╮(╯_╰)╭The thing is, it's not until about halfway through the story that the character is revealed to have this disorder. Near the beginning, "Harrison" mentions that his twin "Scott" (not their real names) is not somebody to smeg with (as I mentioned, Harrison's Simon Tam; Scott's Jayne Cobb). Encounters occur with both of the "brothers". Eventually, the other characters learn that about his disorder.

I'm developing a psychic character for a Mutants And Masterminds session who suffers from Disassociative Identity Disorder (their powers are similar, but with sleight variations). Each identity believes the other one to be their twin sibling (though this wouldn't be revealed until later in the story; inspired by Metal Gear Solid: Portable Ops). Basically, they're Simon Tam and Jayne Cobb.
The thing is, I can't decide on what should trigger the character's identity shift. The Hulk-style "don't make me mad" one's a bit cliche.
