Dr. Wily Stage Strategies

Wily Stage 1: The Dragon boss is weak to Crash Bombs. Place bombs on its head as it passes.

Wily Stage 2: The Boobeam Trap boss requires Crash Bombs placed on each of the five cannons. You need exactly 5 Crash Bombs, so manage ammunition carefully.

Wily Stage 3: Alien Wily is weak to Bubble Lead. However, this is actually a hologram.

Wily Stage 4: Wily Machine 2 is weak to Bubble Lead for its first form (UFO) and Crash Bombs for its second form.

True Final Boss: The Alien form (Wily’s final form) is also defeated with Bubble Lead.

Items (Item-1, Item-2, Item-3)

These items are obtained by defeating bosses and create platforms or rockets:

  • Item-1 (Heat Man): Creates a hovering platform. Essential for certain Wily Castle passages
  • Item-2 (Air Man): Creates a rocket you can ride
  • Item-3 (Crash Man): Creates a series of steps

Metal Blade Trick

Metal Man’s own weapon — the Metal Blade — is the most versatile weapon in the game. It:

  • Can be thrown in 8 directions
  • Has excellent range
  • Costs very little weapon energy
  • Is effective against most bosses
  • Can defeat Metal Man himself in one hit

Energy Management

Always conserve your Atomic Fire — the fully charged shot is essential for Wood Man but the weapon is energy-hungry. Use the uncharged version to conserve energy during stages.

Secret Items

Throughout the stages, there are hidden locations containing:

  • E-Tanks: Energy tanks that fully restore health, carried as inventory
  • 1-Up: Extra lives

Look for slight color variations in walls and floors — bombable or accessible areas are often visible if you know what to look for.
