>>31181600Wll the later has been in the game for a while.
Tyrogue was the same thing, dif stats dif evolution.
Then you got the miniors, who had tons of different colors.
The gender pokemon, like salandit and combee.
Game freak isn't above the hard to get shit.
But I see where you are coming from. The only way I could see it working is making temp fusions.
Both pokemon hold like... a gem or some shit. Once a match you could Temporary fuse them. Thing mega forms but it requires you to sacrifice a pokemon for it. Not permanently of course.
On a side note, I would like an alternate cloyster, when evolved holding a slowpoke tail.
