Psybeam is not a TM and thus cannot be found. The only way for a Pokemon to learn Psybeam is by leveling them up.
Mewtwo doesn't learn Psybeam.
Kadabra learns Psybeam at level 24.
it will learn it at level 36
Psybeam is not available by TM or Move Tutor in HG/SS.
Psybeam is not a TM move. It's learn-able by level up by Butterfree, Venonat, Venomoth, Kadabra, Alakazam, Mr. Mime, Porygon, Espeon, Misdreavus, Girafarig, Remoraid, Octillery, and Porygon2. It's also usable by Pokemon that know Metronome if it's chosen by that move.
Easy. Take out the Fighting Dojo. I suggest to use a Kadabra Lv.30 or higher. Trust me this will level him up if he knows Phsycic and Psybeam two really good Phsycic Moves. You can Easily pwn Them. Once the Dojo is destroyed the Rocket will have moved right of the entrance.
So far my porygon is level 49 and has tackle tri attack zap cannon and psybeam hope i can help =).
A pokemon that knows Charge can, but you will need to get a pokemon from Pokemon White that knows Charge. Same goes for those who own Pokemon White, you will need to get a pokemon that knows Charge from Pokemon Black to activate the time machine.
I hoenestly think that psybeam is one of the best Psycic moves, sadly i dont think you can D:
get a pokemon that knows charge from the opposite game e.g if you have pokemon white get a pokemon that knows charge from pokemon black
