Yes. It is completely possible to catch Mewtwo with an ultra ball.
You can catch Mewtwo easily by using a Master Ball on it or by using an Ultra Ball on it after lowering its HP.
I prefer to use my Master Ball for Mewtwo, but at least use an Ultra Ball.

You can probaly catch him with a ultra ball but I would use the master ball
master ball ultra ball quick ball or a premier ball
if you dont wanna waste your master ball, then the strongest ball will be the Ultra Ball...
You can catch Mewtwo with any Poké Ball and those include the regular Poké Ball as well as the Great Balls, Ultra Balls, Dusk Balls and Nest Balls.
Well it matters what game you have, if you have Pokemon fire red, you can catch it with a master ball
