They didn't make 'em for everything, just some T_T@Mr. Person: They already did make crappy evos and pre-evos for everything. I think that the the games were Diamond and Pearl.
All other Pokemon are genderless as well, so you can never breed (even with Ditto) and Lairon is the end of the Aron evolution line so you never get strong Pokemon and never get Aggron. Also, the TMs are all rigged to teach Struggle.Granted. Your Pokemon all get as many cookies as they can possibly eat. So many, in fact, that they all become obese and die of heart attacks.
I wish that the Aron line was genderless.
