That's not a good reason. I don't see why every Pokemon needs to have an evolution.
well it's more likely. If you didn't notice they made Sudowoodo have a preevolution when it didn't need one. They also made Porygon have 2 evolutions that it didn't need as it started off as a non-evolution pokemon. Same with Tangela.
