However, some weapons break this rule
There's quite a few that do that
Guts Man = Super Arm
Elec Man = Thunder Beam
Flash Man = Time Stopper
Heat Man = Atomic Fire
Wood Man = Leaf Shield
Bright Man = Flash Stopper
Toad Man = Rain Flush
Burst Man = Danger Wrap
Cloud Man = Thunder Bolt
Spring Man = Wild Coil
Shade Man = Noise Crush
Turbo Man = Scorch Wheel
Tengu Man = Tornado Hold
Astro Man = Copy Vision
Clown Man = Thunder Claw
Search Man = Homing Sniper
Frost Man = Ice Wave
Grenade Man = Flash Bomb
Aqua Man = Water Balloon
Dynamo Man = Lightning Bolt
Ground Man = Spread Drill
Pirate Man = Remote Mine
Splash Woman = Laser Trident
Galaxy Man = Black Hole Bomb
Pump Man = Water Shield
Sheep Man = Thunder Wool
Nitro Man = Wheel Cutter
Volt Man = Force Field
Dyna Man = Nuclear Detonator
Wave Man PC = Water Shooter
Also, all the ones from V, RF2, and Strategy don't have the Robot Master's name in them
Also, you could possibly count Cut Man's Rolling Cutter and Strike Man's Rebound Striker, though their names are there, they're part of a larger word
