well i make games so i have to design thhem and give them names that corrispond to their abilitys...Normaly their japanese...eg. A chracter that died in spring → sakura , youmu , or yuyuko
Usually some rendition of my name if naming myself. I try to use the max number of characters if it's short. My name is 9 characters long so I have to shorten it most of the time.
Oh for Pokemon, I usually choose a funny name for myself and an actual person's name from school as my rival. tbh... it's usually a crush so I can make fun of myself later if I ever want to go crazy and get the legendaries I missed.
