I found it a little harder to think of Galarian forms since I was having trouble thinking of British ideas/concepts that haven't already been shown in the trailers, but I think I finally managed to think of a concept that works ;P . Anyway, here's the facts:
Dwebble- Galarian Form
The Rock Inn Pokémon
"In order to deal with the more dangerous predators of the Galar region, Dwebble started using scrap metal left by factories and other machinery to make stronger, more durable shells. Over time, Dwebble's body adapted to make them skilled craftsmen in cutting and reassembling metal. Their exoskeletons are strong enough to pierce through most metallics, their pincers are capable of removing various screws, and their spit has become more acidic.
Galarian Dwebble were used as factories workers in the Galar region when industries started booming. Due to their skills in metalwork, they were called on for fixing any broken machinery and were paid with spare parts for their shells."
