Why Budew had the best implementation out of all pre-evolutions
It's been a while since we've had a pre-evolution to a Pokémon hasn't it? While some would be fine if it stayed that way, seeing them as pointless. I think that one Pokémon in particular showed how they could be used during their debut and that's Budew.
Being the pre-evolved form of Roselia, Budew debuted in Diamond and Pearl and could be found early on in Route 204 which was an area you could go to before the first gym. The first gym itself being the Rock type using Roark. With it's Grass/Poison typing and having access to the fine enough Mega Drain. It would be a good choice against Roark for those who had chosen a Chimchar.
However, if they had put in Roselia, with it having a high 100 Special Attack, it would've made Roark too easy even for early game.
Thinking about how they implemented Budew into that game. I came to the conclusion that if we ever get any new pre-evolutions in the future, they should be Pokemon you get in the early game. A means to access older Pokemon without making the start of the game too easy.
For a few examples...
* Let's say you wanted to have players be able to get Scyther at the start of the game. It'd be overkill to have the fella on Route 1, but if you gave the mantis it's own pre-evolution, you'd be able to let players get it while keeping things balanced. (Also sure you could get the powerful and non baby Flamigo early on in Scarlet and Violet but it was off the beaten path.) * Another example could be that you want to reward a player for exploring with Duraludon being found in an optional area that's blocked off until the first badge. However, that 535 BST on a Steel/Dragon would make it too OP. So why not give it a cute little pre-evolution that's pure steel for players to train up to... I guess level 34 * Two more examples where I had the idea of them being made into retroactive examples of a certain archetype * Yanma getting a pre-evolution to have its line act as an Early Three Stage Bug line in the vein of Vikavolt and Orbeetle * Tangela’s pre-evolution from GS’s beta being brought back so it could take on the role of an Early Plant Pokémon akin to Bellsproute and Oddish alongside the Cherrim line which gets an evolution
Also helps that it'd bring some variety to the early game as well.
Given that in Black and White 2, they had Elekid and Magby be found early on in Virbank Complex, had Pichu in Route 1 for the Alola games, Mime Jr. in USUM's version of Hau'oli City, etc. it seems that Game Freak seems to realize that as well. But keep in mind that it wasn't the case when they first appeared, they were mostly only found via breeding.
So in conclusion, Budew was implemented the best because it let players use a past Pokémon encountered later without breaking the early game and if Game Freak were to make new pre-evolutions, they should be made early game like Budew. #games
