How to get one
No encounter table gives it, on any of the six cartridges. So the game hands it over some other way: a starter, a gift, a fossil, an egg, the Game Corner, a fixed battle or a standing legendary. The site does not index those sources and will not guess which one it is.
What it becomes
It does not evolve.

Generation 2 split Special in two, and not down the middle: the two columns are not one value copied twice.
