>>58823898>The other 2 are retarded though and just reeks of GameFreak being scared to use fanon termsNah. "Starter" was the previous official term, I think it was being used into the early 2010s. Shiny was originally a fan term. Eeveelution was a fan term.
It's about brand management and having the brand be consistent across each language. Interestingly, they threw English fans a bone when they canonized "shiny", since every other region used a version of "different colour", only the English name has this relic from the TCG "shining" terminology.
In Japan, pseudos are called the 600 club, so "Powerhouse" is a simple way to describe them. "First Partner" allows for them to distinguish between baby's first Pokemon and other "Partner" starters, like they did in ZA. I also think it's meant to emphasize them being *partners* rather than something disposable, like a starter home or a starter job, something you're meant to grow out of. They're your first pet, not a pair of training wheels. But the English phrasing is obviously clunky and that makes it a hard sell when "starter" is so engrained.
