PMD isn't canon. It's not like Paper Mario, where stuff still makes some sense, despite the different graphical design and ability.
i.e.: Peach talks in Paper Mario and in his regular games.
In PMD2, Mewtwo is a random, wild Pokemon. He's not hidden away in a cave, saying 'OMG DNA'. PMD2 is also... uh, a retcon of PMD1, would it?
Would PMD2 be a more recent, retconned PMD1, since it has fourth gen and stuff? And Mewtwo is classified as a wild Pokemon?
Look. Mewtwo is going to be hit by Earthquake. He's hit by it EVERYWHERE. If you want to say 'OH, HE CAN MAGICALLY EVADE IT BECAUSE HE LEVITATED ONCE IN HIS GAMES', then you're breaking canon.
The AI thing was badly thought out, I didn't know how to quite explain it. Think of Mewtwo as a wild animal, and trainers as...human beings. Lulz. The wild animal isn't as smart as the trainer (I know some animals are smart, but I'm talking about the not-so-smart ones), and as such, the wild animal attacks randomly due to not have enough cognitive thought to strategize. Mewtwo is afflicted with this. As for Psychic Pokemon, look at Slowbro.
IIRC, Mewtwo WAS in a cave in Mystery Dungeon. His role is pretty much the same as in the main games. However, he's shown to be a bit more aggressive as I saw from a video. Instead of just waiting for the "challenger" (the trainer in the main series entering the Cerulean Cave or the main character and partner in Mystery Dungeon) to appear to him at the end of the cave, he's shown to attack Blastoise and Charizard on his own accord when they entered the cave. Causing explosions everywhere and stuff. Vid is here, found it in the meanwhile

As for the Earthquake, yes maybe it'll hit Mewtwo but it all depends on it. Most likely, he won't float if he musn't. If he must, it's likely cause Bowser is going airbone in the Clown Car. Levitation could only be used as a second option, Mewtwo would likely prefer the ground (as opposed to Falco lolz).
It isn't as far fechted for Mewtwo to float though. He's shown to be able to do it, so why can't he? Also, Bowser's average AI is likely much worse than Mewtwo's. Mewtwo at least tries to set up when encountered in the wild, Bowser is much like "ARRGH IM GONNA WALK INTO YOU TO CAUSE YOU DAMAGE MARIO RAAWRRRRZ".
Talking about the "average" Bowser now, sometimes he does show some sence of planning, but I just remembered fighting Bowser in Super Paper Mario. **** those where some short fights.
I thought we were using one Samus o_O
But it's funny to note, Samus gives the Light Suit back to the Lumineth, but keeps their weapons.
The thing is, Bowser and Spamus can pick these weapons up on their own. Mewtwo can't. PMD doesn't count; it isn't canon.
Mewtwo learned himself moves in Stadium as well. I keep on saying this, cause.. he did. Thunderbolt and Blizzard are clearly TM moves, and wisely chosen as well. Mewtwo is a pretty cool guy. Uhh counters all types, and doesn't affraid of anything. O_O
Problem with Samus for example is that most of the planets where she gets her weapons from are destroyed. Yet we're skipping it all for her, cause Samus is clearly liked a lot. I like her to, so I've got no complains but... it could all be countered as well.
If we apply the same rules Mewtwo gets to Bowser, Bowser first needs to plan a great invasion of the Star Haven to get his Star Rod back, as he loses it canoncially at the end of Paper Mario right? I don't care if he gets it on his own accord or not, cause in the end he also needs to get it right back from the Star Haven to use it. And he most likely can't...
So I say, we skip the "logic" and give characters all their moves which aren't back up.
In Platinum, some legends return if you release or KO them. They don't have their TM moves if you teach it to them.
Then, most likely by using the same logic Mewtwo or any other pPokemon can't have TMs we must assume these Pokemon first go look for Heart Scales to have that one fat guy learn them their moves back right?
