Here’s my overpowered Croconaw that I didn’t evolve. He’s still leveling up. Luckily he did have Ice Punch. It wasn’t necessary but I was super happy upon seeing it. Thanks, @/Firesquids
I like to keep my team full of Pokemon that I like, and I usually like their unevolved forms most! Small and cute is good. Aesthetics are important.
In Pokemon Sword, I absolutely couldn't bring myself to let Sobble evolve, so it stayed small forever. The rest of my team was filled with favourites, so it followed suit.
Blipbug was truly a struggle to work with. But its was on my team so early and its face was just so funny, I couldn't bear to remove it from my team.
The only real problem was having to constantly stop their evolution before getting everstones.
