Protector: Protectors are alters that protect the body, system, host, core, or other specific alters or groups of alters. Physical protectors might take or try to prevent physical abuse or become aggressive in an attempt to defend against physical abuse. Verbal protectors might take verbal abuse or lash back verbally in order to counter verbal abuse. Emotional protectors might take emotional abuse or comfort other alters to soften the effects of emotional abuse. Sexual protectors might take sexual abuse or attempt to instigate sexual abuse in an attempt to feel more in control of the situation. Caretaker alters are a unique type of protector that is focused specifically on taking care of younger, weaker, or more vulnerable alters or external children. Persecutors are another specific type of protector that are often not seen as such but that protect by harming the system themselves in order to avoid outside harm.

Littles: These alters are quite common in systems and are under the age of 13. They are infants and children who are possibly stuck in the age when trauma happened to the core; This isn't always the case but most often is. Littles can also be unaware of trauma or the system and be completely carefree, happy, and living the childhood the core possibly missed. Some may struggle with verbal communication, but can understand complex concepts and ideas. They are not ones 'inner child.' They are usually their own person. Please respect that.

Age Regressors: Age Regression occurs when someone reverts to a younger state of mind, despite their physical age. This is to cope with their trauma that they may have endured at a young age, stress, or a combination of both.
