In my very brief research, these are the Pokemon most screwed over when it comes to playing the story, either because their availability comes way too late or they evolve way too late.
>>58909552you could pretty much any trade evo here
>>58909552whismur's perfectly fine in RSE? you can get it less than an hour in and it only evolves at like level 20 and 40, which is barely after your starter.I would think to add Rhyhorn. I've never found a suitable game to use it in and evolve it fully, unless I'm misremembering.
>>58909565Level 40 feels honestly way too late for the underwhelming power level of Exploud. The line would've been better served being fully evolved at level 30.
the late unova ones are the only real problem here and even then you can get an early Mandi/Braviary in BW2 and Axew is a starter in GTIwell and Slugma but that's more on Magcargo being absolute dogshit not worth it than it is anything else, even in Colo when it's available incredibly early on it's worthless
>>58909552Timburr and Roggenrola are fine. Level 25 fully evolved by Gym 4 is pretty strong.
>>58909552Houndour and slugma were available at a reasonable time in Sinnoh and Hoenn respectively. You could honestly put any trade evo on here now because nobody plays the older games and you have to edit the rom to make it evolve via another method if you want to use it. The Unova mons indeed should have been available earlier.
