What “best” should include
A PokéBonk best Pokémon answer needs at least the game version, mode, starter or unlock state, first upgrades and the point where the run ended. A name copied from a mainline Pokémon ranking does not measure a survivor-style run.
AReliableSurvives a normal run and has a clear upgrade path in the current version.
BSpecialistStrong when the mode, map or upgrade cards match its role.
CNeeds testingInteresting claim, but not enough dated runs to call it a recommendation.
Use the current in-game description first. EarlyWiki will only turn this method into a named ranking after the same test can be repeated across a dated build.
