When you find Mewtwo in the "wild" he knows the moves- Recover, Swift, Barrier, and Psychic. So, it's probably PSYCHIC. Great answer but he does go on to learn psyshock and psystrike i think. 2 extremely powerful moves. my mewtwo is legit lv.100 and he knows both. not 100% certain there both learnable as 1 could possibly be a tm but i really cant remember that :)
Psystrike
Giratina's signature move is Shadow Force.
Only Giratina can learn shadow force. The only thing that proves or said that Giratina can learn the move is because it is it's signature move.....
Splash is a move that is completely useless (with the exception of it in Pokemon Mystery Dungeon, where it deals 5 damage to the opponent and the Pokemon that used it), and is Magikarp's signature move.
hi signature move- Shadow force. (Which he already has) But another good one is earth power :) Hope I helped
Psystrike
The fifth generation Pokémon that naturally learn Psyshock are Gothita, Gothorita, Gothitelle, Solosis, Duosion, and Reuniclus. They all learn Psyshock on level 25. There is also a TM for Psyshock, which many Pokémon from most generations can learn.
Golduck is a dual Water and Psychic type Pokemon. It does not naturally learn the move Psyshock, but it can learn it at any level by use of the TM.
Giratina's signature move is Shadow Force.
triple-h's signature move is spinebuster....
How I do signature move on wwe all stars
Normally, Legendary Pokemon already have learn their signature move when first caught during gameplay or obtain through an official Nintendo event. Their levels greatly vary on when they learn their signature move and some do not even have a signature move like Mew and Mewtwo. (Unless you count Psychic as their signature move.)
Go to 'create a move set' and on the signature move menu, choose edge's signature from the list.
Check on create move sets and go to edge's signature move
his signature is called edgecution, a more like DDT...
psychic.
There is no such TM, but the move is the Signature move of Dialga.
