How is musharna a stretch? That's the most obvious one, they're both based on the same mythological dream stealing tapir monster lol. I'm surprised there's even one of those in Pokemon, but two?Gen V does have a bunch of older pokemon mimics but you're really stretching on some of these. Not every horse is a rapidash knock-off, not every jellyfish is a tentacruel knock-off.
Most of the problem comes from gen V having 150 pokemon again and as a result they have a bunch of derivative fill-ins just to push up the dex number. Every gen has some of these, but gen V has the most because they purposely tried to inflate the regional dex to make the no older pokemon till postgame idea work.
