The Batmobile drove through the streets in town with incredible speed and passing by some ordinary people/monsters and cars.
CIVILIAN: Woohoo! Go Batman!
MONSTER: Keep us safe, Batman! You rock!
Batman/Johnny and Robin parked the Batmobile in front of a shutter door with a green question mark painted on it.
BATMAN/JOHNNY: Hmmm.... this must be Riddler's last room.
ROBIN: What do you think is in there, Johnny?
BATMAN/JOHNNY: I don't know and I don't like it. Stay here while I go inside and check it out.
ROBIN: Wow wow wow... there's no way I'm letting you go there alone. You need my help. What happens if you failed?
BATMAN/JOHNNY: I won't fail.
With no time to argue, Robin exited the Batmobile and grappled up to high vantage point waiting in case Batman/Johnny needed help. The shutter door slowly opened leading the way downstairs to the next Riddler Room.
Batman/Johnny slowly drove the Batmobile inside the shutter door being cautious within its surroundings. Once he drove the car far enough, Batman/Johnny was surprised that this Riddler room was way bigger than the previous two. The room was more like a large racing track. A murder box can also be seen with a crying hostage inside.
RIDDLER: Welcome to your final room, Detective! And yes as you can see, it is race track for your toy car. The goal is simple, finish the race before the time limit expires, that is if you can finish it. But I better warn you, this is my finest work, Detective. My masterpiece. My Enig-ma Résistance!
Before the race track begins, the racing lights lighted into red while the Batmobile performed a wheelspin getting ready.
RIDDLER: So, let us take that inexplicably life-sized children's toy for its one final drive.
The light turned into green starting the race. Batman/Johnny quickly hits the pedal as the Batmobile started to accelerate under the limited time limit. The Batmobile drove through the tunnels and sometimes make hard left turns and hard right turns.
RIDDLER: This is it, Dark Knight. Your Teutoburg! Your bay of pigs! Your ultimate defeat!
As the Batmobile accelerated he racing rode was connected to wall. Batman/Johnny has no choice but to drive the Batmobile through that wall making its way to the other side.
RIDDLER: That's it, Detective, drive faster! Drive headlong to defeat!
The next thing he sees was the race track was formed in a circle like a roller coaster ride.
BATMAN/JOHNNY: I'm disabling the afterburner's failsafe. I need the extra speed.
Batman/Johnny used the Batmobile's afterburners in order to drive through walls upside down in incredible speed like he was riding in a roller coaster without falling.
RIDDLER: What!? Impossible! That cannot be!
The Batmobile was driving through the race track where there are colorful walls blocking the way. Whenever the Batmobile was about to get near it, the wall will automatically pull back up to give the Batmobile some way.
RIDDLER: You should've fallen into your death! I calculated the curvature precisely! I'VE GOT THE EQUATIONS RIGHT HERE!
The next challenge was the Batmobile driving through the green lights on the floor trying to avoid it so that it won't get squashed by those mechanical cube bricks.
Batman/Johnny was almost halfway to the finish line, the dangerous task he does next is to drive pass through some dangerous spinning blades. The Batmobile was able to pass by them carefully without a scratch.
RIDDLER: I AM THE RIDDLER AND YOU SHALL NOT DEFEAT ME!
After passing through those spinning blades, the Batmobile has yet again to drive through the walls and make its way to the other side but only this time, it needs to avoid those smashing cube bricks again.
RIDDLER: STOP. NOT. DYING!
The finish line was just ahead of Batman/Johnny. He hits the pedal and activated the afterburners as the Batmobile accelerated fast then passes through the finish line. A celebration noise and sparklers appeared for Batman/Johnny's victory.
RIDDLER: You did it. The hostage. Now the hostage goes free. Those are the rules and I have to follow them, don't I? I set them after all!
The Riddler said in annoyance and in humiliation. The hostage was freed when the murder box opened itself. Batman/Johnny got out from the Batmobile and went up to the hostage to check up on her.
HOSTAGE: Where is he!?
BATMAN/JOHNNY: Me and Robin will deal with Riddler, ma'am. Just give me the trophy.
HOSTAGE: Trophy?
BATMAN/JOHNNY: He gave everyone else a Riddler Trophy. Why didn't he gave you one?
HOSTAGE: He sounded like he thought you'd die down here. I guess he was wrong. Is there anything I could do?
BATMAN/JOHNNY: No. stay here and wait for Commissioner Gordon.
Batman/Johnny pressed some buttons on his right gauntlet and it showed a holographic scree of Alfred, who was in the Batcave.
BATMAN/JOHNNY: Alfred, we've got a problem. I've solved the last Riddler room, but there wasn't a Riddler Trophy.
ALFRED: What is he up to?
BATMAN/JOHNNY: I don't think he thought I'd defeat his last room but he's still got hostages. If there's still alive, me and Robin will find them. Search every record about the building he's used in the Batcomputer. There might be a connection.
ALFRED: It does indeed. They were all owned by Sherman Fine, he acted a some sort of a property Broker. The rooms were bought anonymously by a fellow named 'Enigma'.
BATMAN/JOHNNY: Riddler's alias. It's a perfect match for his M.O. Are there any rooms he purchased?
ALFRED: There is one room that might interest you. Sending you the location now.
BATMAN/JOHNNY: Thanks, Al. I'll check it out.
Batman/Johnny checked the location of the Riddler's potential hideout through his gauntlet. After the hostage was safe and secured by the police, Batman/Johnny meets up with Robin again on a rooftop.
ROBIN: (*chuckle) So, did you miss me or what?
BATMAN/JOHNNY: The hostage is safe and I also have a possible lead on Riddler's whereabouts.
ROBIN: Alright! Then let's go get him!
