To defeat Knight MacFright, you must exploit his charging attack and his armor. Stun him with your Strobulb, then use the Poltergust G-00 to pull off his armor and slam him.
Here's a step-by-step breakdown:
- Dodge the Charge: Knight MacFright will charge at Luigi. Avoid being hit by dodging out of the way.
- Stun with Strobulb: After the charge, when Knight MacFright pauses, use the Strobulb to stun him. This is crucial as Professor E. Gadd suggests.
- Armor Retreat: When stunned, King MacFrights will retreat inside his armor suit. This is your cue to act.
- Plunger Time: Fire a plunger at Knight MacFright's armor using your Poltergust G-00.
- Slam Away: With the plunger attached, pull back to rip the armor off, exposing King MacFrights. Then, slam him repeatedly to inflict damage.
- Repeat: Continue this process (dodging, stunning, pulling armor, slamming) until Knight MacFright is defeated.
Remember to keep moving and avoid his attacks. The key is to time your Strobulb flash correctly to stun him after his charge.
