Boss 8: Rhedogian

Struggling with the Rhedogian boss fight in Metroid: Other M? This guide breaks down its attacks, weaknesses, and the strategy you need to come out on top.

Stats / Weaknesses:

• Rhedogian: Weak point is its eye when it turns red.

Phases:

1. Standard Combat: Rhedogian fires missiles.
2. Red-eyed Attack: Rhedogian's eye turns red, signaling a powerful attack.
3. Retreat: Rhedogian eventually flees.

Strategy:

• When Rhedogian attacks with missiles, use your Sense Move to dodge them. Keep your distance and fire regular beam shots when it's not actively attacking. It will dodge charge shots if it's not in an attack animation, so stick to rapid-fire beams for consistent damage.
• Try to Sense Move away from Rhedogian after each dodge. It's a good idea to start charging your beam *before* you dodge, so you can immediately release a charge shot right after evading its attack.
• When its eye turns red, this is your prime opportunity! Fire a missile at its eye as quickly as possible. If its horns were frozen (this isn't explicitly explained how to freeze them in the source, but it's mentioned as a condition for the Lethal Strike), you can then go in for a Lethal Strike. This Red-eyed attack can be triggered more frequently by consistently hitting Rhedogian with missiles.
• After landing a few more charge shots, Rhedogian will eventually run away.
• Once the boss fight is over, head back to the elevator. From there, Speed Boost up to the door and then Shinespark down the hallway to the right. You'll need to destroy the Zoomers that get in your way.
• In the next room, use your Morph Ball to enter the hole in the pipe on the wall. Bomb the first slot you find.
• Exit the pipe and position yourself between the empty and full tanks. Switch to Search View. You'll need to shoot a switch through the empty tubes using your Wave Beam.
• After activating the switch, enter the tunnel and roll back to the elevator. From there, travel to the Main Sector, and then make your way back to Sector 3. Use your Concentrate ability to replenish any missiles you might have used during the Rhedogian fight.
