Part 11

Phase 1: Riddler Robots
You'll start this fight in an arena where The Riddler is protected by an invulnerable green shield. Don't bother attacking him directly. His main attacks are a ground slam if you get too close and a powerful green death laser aimed at either Batman or Catwoman. The real threat here is the army of Riddler Robots he summons. You need to destroy all of them to proceed. Remember, Batman can only target blue robots, and Catwoman can only target red ones. Be extra careful, as The Riddler can change the color of the robots mid-fight, forcing you to switch characters quickly to attack the correct targets.

Phase 2: More Robots and The Riddler
After collecting all the Riddles in Gotham, return to the orphanage to face The Riddler again. He'll emerge from the floor with the same attacks as before: the green death laser, a melee ground slam, and the ability to change robot colors. He'll summon another large group of Riddler Robots. Initially, you'll only control Batman, so focus on destroying the blue robots. Watch out for The Riddler changing some to red – avoid hitting those.

Catwoman Joins the Fight
After a short while, Catwoman will join you, allowing you to switch between characters. Use her to take down the red robots while Batman handles the blue ones.

Damaging The Riddler
Once all the robots are cleared, The Riddler's shield will temporarily drop. This is your chance! Get close and attack him to trigger a cutscene that will reduce his health by a third.

Repeat the Cycle
After taking damage, The Riddler will summon another wave of robots. You'll need to defeat them all again using both Batman and Catwoman. Once they're gone, his shield will drop again, allowing you to attack him directly to take off more health. Keep repeating this process of defeating robots and then attacking The Riddler when his shield is down until the fight is over.

Mission End
After you've finally defeated The Riddler, drive him back to the GCPD to complete this Most Wanted mission.
