If I didn't know what POK Erythroid Myeloid Ontogenic factor was, I would of been laughing and crying my face off.
I love pokemon, but it wants to KILL me!

You think a Ditto can get cancer by transforming too much? I mean, it would be constantly rearranging its genetic code.

You have a point...
But then it can also gain immunities to cancer.

That's actually not true. Cancer is a genetic abnormality, not a disease. So he can't technically gain immunity to it. Theoretically, since he can alter his code quite easily, he could potentially fix the abnormality and cure it though.

Dittos possess the cure for cancer.

You don't need to get all scientificy on me. XD
I just, JUST went over all of this in my Biology class. I still need to take the test. 8O
I forgot to go to school today.

Dittos possess the power to do anything.
Even blow up the moon, like Robotnik! 8D

You forgot? How do you forget something like that? Unless you "forgot", in which case it makes more sense.

Yes, Dittos possess the power to do anything. They are gods! Worship them! All hail the mighty Ditto!

Then how come you can only use him on Super Smash Bros.: Melee when your using the Action Replay to cheat?...

Oh, duh.
It's probably because he was so almighty, that putting him in the normal game was not worthy to contain his greatness.

And even with Action Replay, using him doesn't do anything, you know why?
Because attempting to program the sheer awesomeness that is his power would've blown the minds of mere mortals.
