And on the subject of Route 213, Binacle and Barbaracle are Pokemon I think would also fit there, as well as some other shoreline routes. Luckily, Sinnoh doesn't have Pokemon encounters tied to Rock Smash, so you won't have to worry about seeing them everywhere through that!

Given Inkay and Malamar's affinity for beachfront habitats, they would fit right in as encounters on Route 213!

(And while this isn't a new family, per se, I wanted to mention Sylveon here since I hope they wouldn't retroactively remove its existence like the new evos in HG/SS)

In the event that we get remakes of Diamond and Pearl, I think Spritzee and Swirlix make sense as an extra pair of version exclusives on Route 208, right outside Hearthome City and its Contest Hall. (And if we get a Platinum remake like I want, they can both coexist!)

This may not be Sword and Shield, but I do think the Honedge family has a place in Sinnoh as a new Steel-type that could make its home within Iron Island

Do you remember when Gogoat riding was hyped up to be a big thing and then Gogoat stopped existing after X and Y? I think these guys would make a lot of sense on the western end of Route 211, right next to Eterna's Grass gym (riding not included).

Given Floaroma's whole flowery aesthetic, it'd be a crime if you couldn't find the Flabebe family around the area. Even though Floaroma Meadow doesn't have traditional wild encounters, I'd argue Flabebe is worth making an exception for; otherwise, you could have it on Route 205.

I would not be surprised if whoever designed Heatmor and Durant wanted them to be part of the Fuego Ironworks but missed the chance to get them in Sinnoh. They're too perfect for that area! Also, while it's not *technically* part of Sinnoh, Stark Mountain makes sense for them too

Mienfoo gives me very strong Route 214 vibes. Though, considering that Game Freak has really enjoyed putting them on mountainous areas lately, I could also seem it being an encounter within the top reaches of Mt. Coronet

Here comes everybody's favorite Pokemon. Stunfisk strikes me as a Pokemon that would make a lot of sense but would be confined to the Great Marsh instead because Game Freak knows people want to pay for the chance to encounter it

Cubchoo and Beartic make perfect sense as encounters for Lake Acuity. Sinnoh could use a little more reason to get you to actually surf to those isolated patches of grass besides TMs that were purchasable at Veilstone!
