How to Deal with Net's Flames in Mega Man 3 (Game Boy)

You cannot extinguish NetNavi Net's flames in Mega Man 3 (Game Boy / Mega Man III / Rockman World 3). They are an attack pattern, not an environmental hazard.

Effective Strategies

• Mobility: Jump over low flames; slide (Down + Jump) under high arcs.
• Range: Use your current weapon (preferably Needle Cannon, Spark Shock, or Shadow Blade) to damage Net from afar.
• Rush Coil/Jet: If acquired, Rush Jet (Item 2) lets you hover over flame walls entirely.
• Pattern Recognition: Net cycles: Flame Wave → Teleport → Flame Pillars → Charge. Learn timing.
• Energy Conservation: Don't waste Weapon Energy on minions; save for Net.

Note on Version

Game Boy Mega Man III (1992) condenses NES Mega Man 3 Robot Masters. Net (from Mega Man Battle Network) does not appear. If you mean Fire Man / Heat Man / Burner Man stages, the same evasion principles apply.

Quick reflexes and smart weapon choice win the day.
