Scizor is definitely a good Bug type, but to obtain it, you need to trade. Good physical Bug types are Pheromosa, Scyther, Scolipede, and Golisopod. Good special ones are Galvantula, Ribombee, Vikavolt, Orbeetle to an extent, and Volcarona. I do definitely recommend Scizor, it's excellent, but it being a trade evolution hinders it. Here's a set:
Scizor @ anything
Ability: Technician
- X-Scissor / U-turn
- Metal Claw / Bullet Punch
- Brick Break
- any other physical move
The physical Bug type I recommend the most outside of Scizor is definitely Scolipede. Here's a set:
Scolipede @ Life Orb / anything else
Ability: Speed Boost / Swarm
- Megahorn
- Posion Jab
- Earthquake
- Throat Chop
The special Bug type I recommend is Volcarona , but if you can't get that, Ribombee.
Volcarona @ Silver Powder
Ability: Swarm / Falme Body
- Quiver Dance / Psychic
- Bug Buzz
- Flamethrower / Fiery Dance
- Giga Drain / Psychic
Ribombee @ Silver Powder / Pixie Plate
Ability: Shield Dust
- Pollen Puff / Bug Buzz
- Dazzling Gleam
- Energy Ball
- Psychic
Hope I helped!
