@Noqanky:
It also has less of a movepool to draw from than Scizor.
Scizor is also probably more prevalent competitively and as a result has more of an audience than scyther.
Scizor also allows for an extra gen II pokemon to be featured as opposed to ANOTHER gen I pokemon.
And yea, mega evolution makes for a freebie ultimate form or w.e. those are called. I forget.
Design-wise, Scizor is also a nice foot taller than Scyther so it aesthetically looks less stupid in a fighting game. I also personally see it as a cleaner design due to the roundness of its shape, sharpness of its colors… I definitely think it'll look cooler in a shiny, high-end graphics game where everything looks shiny than scyther would.
Okay yeah sure but you are missing a very key component on why Scyther is superior to Not!Scyther.
! Scyther has scythes for hands.
