Yes it is a very good Pokemon c:
Yes it is an very fast pokemon.
well bellossom has a good sp def. and it doesnt have a double weakness, but heracross and scizor have really good attacks and scizor has better defenses than heracross overall i'd choose scizor
Scizor is a Steel and Bug type pokemon.
You can't get scizor on Pokemon leaf green. However, you can trade if you have Pokemon fire red.
you can't get scizor and not even syther in Pokemon sapphire, only by trading
No. Scizor can't use the stone edge move in Pokemon.
no
no one
NO
Scizor is #212 in the national pokedex, and it is a Bug-Steel type Pokemon.
To rescue Scizor in Explorers of Darkness, you need to unlock the Marine Resort location and complete the missions there until you encounter Scizor. Rescue Scizor by defeating the Pokemon that has lured it into a trap. This will make Scizor grateful and it will join your rescue team.
Unfortunately, you can't get Scizor in Pokemon Ruby. The only way to get it is to trade it from Pokemon FireRed. Well, actually, there's no way of getting Scizor in FireRed either but to have it in FireRed too, you will need to catch a Scyther and evolve it. Hope I helped :)
