Are there any Pokémon that get weaker when they evolve?

Just popped into my brain

This can mean in terms of BST, but also factors that make Pokemon less usable such as a worse typing, ability or other factor that hinders the Pokemon when compared to its previous form.

Technically, Shedinja has a lower stat total than Nincada, but I think it’s still useful. Scizor isn’t necessarily weaker than Scyther, but it has the same base stat total, making Scyther a popular not-fully-evolved Pokemon. Other Pokémon like Slaking, Chansey, Type: Null, and many more can be argued to be worse than their pre-evolutions, but not in base stat total. This makes Shedinja the one-and-only special Pokémon to be “worse” than its evolution in stats.Source: Pokemon DB

These Pokemon have at least one stat that’s lower than its pre-evolution’s stat.
