I have about 5 fire types each named Blaze and Flare. Also when i first got Diamond I named Piplup "Pip."
More unoriginal names for my pokemon:
BruceLee the Hitmonlee
Shadow the Umbreon
Sparky, Sparx, Litening, or Bolt for any electric type
Inferno the Infernape
Empress or Emperor the Empoleon
Terra the Torterra
Sometimes I even name my pokemon for the moves I use a lot like BubbleBeam for Squirtle or Piplup or Flamethrower for Blaziken or Typlosion.
And since I wasted my Master Ball on Dialga in Diamond it took me forever to catch Mesprit. When I finally did I named it "Hard2Catch" and I named my Ralts "Bitch" in Emerald because it took me forever to find one and I was mad xP
