User blog comment:Alpha71/Avatar Aang vs Mewtwo/@comment-5338740-20120526065239/@comment-5138827-20120527185441

Mewtwo wields pokeballs in the movie;this was a combined version of various Mewtwo's to try and potray him as close to most powerful as powerful. I do admit the pokeballs were part of the creativity of the man who designed this profile however in a version of the movie I believe they were used as blunt thrown objects and even captured a pokemon trainer ( i know there were multiple versions of that movie).

Mewtwo uses a huge spoon in the manga, much bigger then Kadabra's.

Yes it does. Avatar Roku specifically says that Aang channels all the knowledge and experience of the past Avatars in that state.
