The SCP Foundation has a term for what you want to be, and dealing with them isn’t exactly pretty:
Reality Benders (Type Greens) have a certain mystique among GOC operatives. They have been attributed a variety of powers, from immortality to mind control. Some operatives even argue that it is impossible to silence a Type Green, and it is suicide to even try.
Bollocks.
The truth is, Reality Benders are human, and they have human flaws. Consider the following:
Reality Benders cannot predict the future and can be taken by surprise.
Reality Benders have limited range and cannot affect what they cannot perceive.
Reality Benders cannot impose their will on anything if they have no will to impose.
Reality Benders have human foibles and can be manipulated emotionally and/or rationally.
Note that this holds true for 95% of Type Greens. For the 5% that this does not apply to… well, you've got a slight problem.
PHASE 1: Denial The subject refuses to acknowledge their Special Talent. The Type Green will attempt to rationalize away their abilities by various means. In some cases, the Type Green will end here: their ability will be self-suppressed, and they will not proceed. However, most then proceed to:
PHASE 2: Experimentation The subject acknowledges their abilities and begins to test the limits of their powers. In general, Type Greens tend to experiment in one of two patterns: slowly, methodically, and carefully, advancing a small amount at a time, or in a small number of sudden jumps. In any case, the subject will generally remain in this mode for some time, before proceeding to:
PHASE 3: Stability The subject reaches the limit of their powers, and determines the boundaries of their abilities. The Type Green achieves control over their reality shifts, and can manipulate them as necessary. More importantly, they can choose not to utilize their abilities, if needed.
Phase 3 is characterized by attempts to live a "normal" life. The subject will continue in normal routines, and aside from necessary precautions to prevent losing control, will utilize their abilities only in private, and only in a manner that will not harm others. These Type Greens may be classified as Threat Level 1 (monitor, do not engage), but should be monitored closely, due to the risk of proceeding to Phase 4.
PHASE 4: The Child-God Sadly, the majority of Type Greens will end at Phase 4. During this phase, the reality bender becomes obsessed with the power it possesses and will attempt to utilize it for personal gain at the cost of others. This phase is marked by reduced empathy for other humans, inability to accept personal faults, and increased megalomania.
Although warning signs are numerous, the key aspect of a Phase 4 is the use of their abilities to manipulate other humans. Teenage and young adult Type Greens will typically use their abilities for sexual purposes, while children will attempt to make strangers their "friends." Older adults may attempt to manipulate others for love or financial gain. Although a few cases have resulted where the Type Green then reverts to Phase 3, 99% of them will remain at Phase 4 until eliminated. For this reason, Phase 4 Type Greens should be considered Threat Level 5 (Immediate Threat) and eliminated immediately.
