I have come up with a ghost/steel type pokemon called Meterroir:
Word origins:
Metal: a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
Terror: extreme fear.
Noir: french for black.
Abilities: Levitate
Pressure
Magic Guard (Hidden ability)
Stats
Hp: 140
Atk: 5
Def: 125
SpAtk: 100
SpDef: 130
Spd: 100
Base stat total: 600 (pseudo legendary)
This pokemon is cool because if it has levitate, it only has one weakness - Fire. And unlike scizor, it only has a 2x weakness against fire as oppose to scizor's 4x weakness to fire. It also has four immunities (fighting, normal, ground, poison), seven 2x resistances (flying, grass, psychic, ice, rock, steel, dragon) and one 4x resistance (bug), making this type combination the most defensive to date. Meterroir has really good defensive stats it back up the great typing, plus great hp, and reliable speed and SpAtk would make this the best pseudo legendary pokemon IMO.
