Out of Character Permissions:
Backtagging: yes please!
Fourth walling: obviously Pokemon is a very popular series, and your character may know of it - and of Mewtwo - ICly. For these situations, I am fine with general fourth-walling ("Pokémon is a game on my world!" "I used to have like fifty Pokémon card decks!") but if possible would like to avoid specific fourth-walling ("I totally caught you in FireRed!" "Man, your movie had really shitty music!").
Content warnings and sensitive subjects: please let me know if the following subjects come up: trypophobia, body horror of the "thing inside you that shouldn't be inside you" variety, sexual assault, pet death.
In Character Permissions:
Physical affection: sure! He will not know how to respond.
Romance: this will definitely take some work ICly, but yes!
Violence: yes, let's plot it out!
Injuries: yes, let's plot it out!
Death: very unlikely, but not off the table – let's plot it out
Telepathy and mind-reading: this would actually be very interesting given that Mewtwo himself is capable of this. Let's plot it out!
Content warnings and sensitive subjects related to the character: violence, blatant disregard of scientific ethics, slavery/questions of personhood, mind control, existential dread?
Permissions for YOU:
Here's a quick rundown of Mewtwo's canon powers and a convenient textbox for you to fill out for our CR!
Telepathy: actually his main method of communication - in this case I'm talking about private/long-distance telepathy. This ability may be used often with friends or allies. (If we are threading and you would like Mewtwo to pick something up mid-conversation, just let me know as well!)
Mind control: pretty much what it says on the tin. In the first movie, Mewtwo maintained this on Joy for weeks, able to use it even when the two were not in the same vicinity. This ability is very unlikely to be used.
Telekinesis/levitation: Mewtwo lifts. WITH HIS MIND. Comes in both painful and nonpainful flavors, and can even be used through TV screens! This ability will be used in fights, and if a character asks to be levitated then yeah he might do it I guess.
Memory erasure: again, what it says on the tin. Used both in conjunction with mind control and by itself, Mewtwo has done this several times, and it seems to be able to span long periods of time/be targeted towards specific topics (for example, any knowledge of Mewtwo the person might have). It's possible that vague impressions of feelings might remain afterwards ("I can't say why, but I feel as though I've been utterly defeated"). This ability is very unlikely to be used.
