Because this is a hack, you can not trade Pokemon in order to evolve them, and because it’s Pokemon Fire Red – You can follow Pokemon Fire Red Walkthrough to play this game, the time based evolutions don’t work either. Due to this, certain Pokemon’s evolutions have been changed. Also, evolving by holding certain items and leveling was a mechanic not introduced until generation 4, so my workarounds tend to involve evolution stones, friendship, or just reaching a certain level. Here is Pokestuck Fire Red Important Evolution Changes. I will list these changes here:
Poliwhirl evolves to Politoed via Sun Stone
Kadabra evolves to Alakazam at level 33
Machoke evolves to Machamp at level 40
Graveler evolves to Golem at level 38
Slowpoke evolves to Slowking via Moon Stone
Onix evolves to Steelix via Moon Stone
Haunter evolves to Gengar at level 38
Seadra evolves to Kingdra via Water Stone
Scyther evolves to Scizor via Moon Stone
Porygon evolves to Porygon2 at level 35
Eevee evolves to Espeon via Sun Stone and Umbreon via Moon Stone
Feebas evolves to Milotic at Max Friendship
Clamperl evolves to Huntail via Moon Stone and Gorebyss via Sun Stone
Feebas evolution was changed simply for ease, as Beauty is an invisible stat in FireRed which makes it very difficult to achieve Max Beauty.
Because there is now a higher demand for Sun Stones and Moon Stones, they have been made purchasable at the Celadon City Department Store alongside all the other evolution stones. Please note that the National Dex lock is still in place, so attempting to evolve your Poliwhirl into a Politoed or your Eevee into an Espeon before defeating the Elite Four will not work. Well, the end of Pokestuck Fire Red Important Evolution Changes.
