Anyway, here are my Pokémon that has nicknames and their inherent meanings:
Swellow (shiny): Adolphe, named for Adolphe Célestin Pégoud, an early aviatior who became the first fighter ace.
Infernape: Saiyuuki, the Japanese transliteration of the Chinese name of the story "Journey to the West". One of the main characters in the story was the Monkey God Sun Wukong, on which Infernape was based on.
Luxray: Remscheid, named for the place in Germany where Wilhelm Conrad Röntgen, the inventor of X-rays and whose name served as the basis for Luxray's Japanese name, was born.
Staraptor: Dakota, named after the famous plane.
Roserade: Trompeur, French for deceive.
Gyarados: Hydraco, combination of the words "hydra" and "draco"
Lucario: Auralis, from the word "aura" (Lucario is the Aura Pokémon).
Murkrow: Sicily, named for the place in Italy infamous for it's mafia.
Steelix: Metallurgy, the name for the study of metals.
Gloom: Rafflesia, named for the largest single flower in the world, on which Gloom was based on.
Fearow: Horikoshi, named for Jiro Horikoshi, the chief engineer of several World War II Japanese fighters, including the A6M Zero.
Skarmory: Aileron, the name for a part of an airplane's wings.
Swablu: Tyl, another name of a constellation called Epsilon Draconis, and which was the basis for Swablu's Japanese name.
Porygon: Seizure, obvious reference to that infamous incident...
Wingull: Wingay, named for someone I know from an IRC network.
Seaking: excess (small "e"), named for someone on a UI customising site I go to who randomly blurted out the Seaking meme in one of his comments.
Mantyke: Lunacy, a random name I gave it after having an unexpectedly hard time catching it.
I also nickname most of my HM slaves, but using numbers instead of proper names to identify them. The numbers come from the bus route's numbers here, and they mainly relate to what I mainly use that particular HM slave for:
Hoothoot - 34, a route that goes to the airport. Used as my Fly and Defog slave.
Zubat - 858, another route that goes to the airport and also another Fly/Defog slave, used before I decided on my Hoothoot.
Golbat - 53, yet another route that goes to the airport, and my first Fly HM slave. Was also used in my hunt for Mespirt (it was speed-boosted with Carbos and had Mean Look).
Goldeen - 194, a bus route that serves Singapore's Jurong Bird Park, home to the world's largest man-made waterfall; therefore my Waterfall and Surf HM slave.
Bibarel - 178, my most important HM slave, knowing Rock Climb, Rock Smash, Strength, and Surf. The bus route she (yes, this Bibarel is a female) is named for uses mostly old buses that - coincidentally or not - have an interior colour scheme identical to that of Bidoof/Bibarel's colours.
I also have the 28 forms of Unown whose nicknames are plain weird, but I will spare you those...
