>>52559087Power Plant evolving Magneton wouldn't make sense, you need a special magnetic field, not jut some random shithole.
In general, the argument can be made that the evolutions can't be added because then why didn't we get these evolutions back in Gen 2? They used to be much more anal about having these things make 'sense'.
Gen 4 is full of shit like that, it's why all cross-gen evos require brand new items or evolution methods, and why new baby mons require incest (Though that was introduced with Wynaut already)
