It was argued that the combination of obscurity/non-correlation of the names (and, at least from me, the relative 'unimportance' of the [differently-named] creatures and genericness of some of them (for comparison, only Golem and Kabuto have a "_(pokemon)" suffix, with Gloom appropriated to the PKMN)) made for using these familiar names the easier path (it was a flood of alias suggestions from me that solidified this action).
Do agree we oughta use "Pocket Monsters", though I'd only argue for "pocket_monsters_special" ("Pokémon Adventures" in English publications).
it says a lot about the sheer justification to adding this to the tag PANIC pool, when over 30 comments STILL form a shorter list than the list of tags. especially given most of the tags are character names.
