I’m sorry, but Terlor’s answer is incorrect. Note that I am counting the Generations of the first evolution.
Which generation has the most Pokemon which evolve by tradingwhile holding an Item?
Poliwhirl -> Politoed(King’s Rock)Slowpoke -> Slowking(King’s Rock)Onix -> Steelix(Metal Coat)Rhydon -> Rhyperior(Protector)Seadra -> Kingdra(Dragon Scale)Scyther -> Scizor(Metal Coat)Electabuzz -> Electivire(Electrizer)Magmar -> Magmortar(Magmarizer)Porygon -> Porygon2(Up-Grade)
Porygon2 -> Porygon-Z(Dubious Disc)
Feebas -> Milotic(Prism Scale)Dusclops -> Dusknoir(Reaper Cloth)Clamperl -> Huntail(Deepseatooth)Clamperl -> Gorebyss(Deepseascale)
Spritzee -> Aromatisse(Sachet)Swirlix -> Slurpuff(Whipped Dream)
So your answer would beGeneration 1if you count the traded Pokemon, andGeneration 2if you count the newly evolved Pokemon(the result).
