Question

Why is it that Scizors base stat total 500 hundred doesn't go up when it evolves from Scyther?

Answer 1

Well, other than Game-Freak wanted it that way, there I'd a potential in universe explanation.

The metal coat appears to be some sort if unnatural material, as it changes Pokemon into radically rare and artificial looking forms. As such, it is likely man-made, and while Steelix occur naturally deep beneath the earth, Scizor may itself be a man-made evolution of a natural Pokemon, kind of like Electrivire and Magmortar. As such technology is likely very young and underdeveloped during the time of the Johto games, it is unable to increase Scizor's overall power, just rearrange it and change its typing.

Conventionally speaking however, Scizor may have been intended to be a form-change, but the technology for the game just wasn't that advanced in Gen 2, or it could be that if Scizors stats increased in evolutions the creators feared it would be too powerful.

Anyway just my two cents. Hope this helps.

That makes sense thank you.

Answer 2

it's more if game freak logic than anything else, they just decided to make it that way. plus, syther didn't originally evolve, and was already a strong Pokemon, they didn't want to make it's evolution to over powered. plus specialize in different stats, like how scizor is slower than syther.

OK thanks

Answer 3

It did not go up because it did not need to. They just divided the stats differently from Scyther to Scizor.

Scizor now has a Steel shell, making him hit a lot harder and more durable, meaning his Attack & Defense goes up. But Steel is heavy, so his Speed drops. So while his Atk & Def rise, they are met with an equal and opposite drop in Speed.

If his shell were made of Carbon Fiber, the BST would have risen.
