Electrive isn’t the only Pokemon that was added to an existing Pokemon’s evolutionary tree after their initial debut. In fact, it has become a very common occurrence within the Pokemon franchise and has allowed the developers to keep fans engaged with older Pokemon and bring forgotten monsters back into the spotlight. Here is a list of all the Pokemon who had the same treatment: • Rhydon-Rhyperior • Magmar-Magmortar • Electabuzz-Electivire • Misdreavus-Mismagus • Gligar-Gliscor • Porygon2-PorygonZ • Murkrow-Honchkrow • Sneasel-Weavile
