Nicknaming Pokémon is probably one of the oldest features of the franchise, and if you ask me one of the best.
Now, Nicknaming Pokémon is not always easy. Some Pokémon are just harder to nickname for some people than others. So now I ask, what are your Sigature Pokémon nicknames?
Disclaimer: this is not nicknames for your Signature Pokémon, but nicknames you always.usually use.
Here are a few of mine:
Shiny Gardevoir = Lucina (My favorite FE Princes, if not gaming princes. she also has Blue hair.
Roserade = Summer (Reference to Summer Rose, mother of Ruby Rose. Who is the Main Protagonist of RWBY)
Togekiss = Flügel der Freiheit/Flügel for short (it means Wings of Freedom)
Infernape = Zuko (should make sense)
Emboar = Iroh (Same reason as Nape. And Iroh is chubby like Emboar)
Serperior = Sniper (My first starters nickname. I just can't do anything else for it)
Klefki = Key Resonator (reference to Jack Atlas and his Resonator monsters)
Azumarill = Truck (It hits like a truck. nothing more to be said)
Mega Charizard X = Firewall (reference to Firewall Dragon)
Mega Charizard Y = Topologic (reference to Topologic Bomber Dragon)
Yanmega = Heather (SHELLY!)
Scolipede = Diesel (idk. I'm bad at nicknames)
Samurott = Jack (Captain Jack Sparow. Samurai Jack. It writes itself)
Venusaur = Fizzlebeef (the true savior of Mankind)
Mimikyu = Kevin (the singer of Ghost town is called Kevin Ghost. Mimikyu is a ghost)
Primarina = Azura/Shigure based on gender (FE Fates nicknames)
Lycanroc Dusk = Sif (The Great GreyWolf from Dark Souls)
And those are all the ones I could think of at the top of my head.
