It's all a matter of creativity and intelligent.
Boring and uptight casuals don't give nicknames at all.
Retarded edgyfags with a ruined childhood choose names like DARKDRAGON or SLAYERBLADE. They also like Scizor and Hydreigon.
And then there are creative and intelligent people who pick witty, inspired and entertaining names for their Pokémon.
Only then you are using the game's fullest potential of individualization.
