This is a very dark story that includes forced feminization and non-consent. It involves Jason Todd, the second Robin after Dick Grayson. Jason Todd was killed in the "Death in the Family" storyline by the Joker. Here I'm presenting an alternative to that where the Joker had a different fate in mind for Robin.
Also, just to avoid any unneeded complications, Robin is 18 and just out of high school.

Arkham Asylum for the criminally insane tried its best to maintain containment of the inmates it housed, but that proved to be very difficult for some of the most devious and maniacal of its denizens. Sirens blared and cops swarmed the streets as once again the population was alerted that Gotham's most insane criminal, the Joker, had once again escaped the confines of the Asylum.
The city buzzed with a thin panic and Batman, self-appointed guardian of Gotham, took to the roof tops to begin the search for the clown prince of crime. He brought his sidekick and ward Jason Todd who had taken the mantel of Robin after Dick Grayson had left to become Nightwing. Over the years Jason had been difficult to manage, a head strong lad with a highly stubborn streak. Luckily he'd graduated high school and was accepted to Gotham University, where Bruce hoped the young man would cool off a little. In fact he didn't want to disturb Jason from his studies, but a code green meant all hands on deck.
"Are we going to run a standard search pattern? Check out all chemical and toy factories?" Robin asked as rain started to fall on the roof of the building they perched on as they monitored the city.
"Best to start with those locations, since that's' where he prefers to set up shop. But we need to expand to other locations. He's been getting trickier, more devious with his recent machinations. Something has popped in his brain and I don't like how determined he appears." Batman mused, not taking his eyes off the street.
"Well there's that old warehouse full of boards games." Robin suggested.
"That's not Joker's MO." Batman said curtly.
"I know, but they make playing cards there. It's a stretch, but if he's getting more devious he might be working outside his normal routine." Robin countered.
"Fine, go investigate it. It sounds like a remote enough possibility you should be safe going solo, just be careful." Batman conceded.
"Where are you going?" Robin asked, excited he'd get to do the search independently, even if only because Batman thought there wasn't a chance Joker would be there.
"Someone has to investigate the more fruitful leads. There was a raid on one of the chemical plants just before Joker escaped, so I'll start there and work my way out. Keep your radio handy and alert me if you see anything suspicious at all." Batman warned just before we shot his grappling line and took off into the night sky.
Robin was left along on the roof top feeling like he'd won a small victory, and he shot his own grappling hook and headed off towards the game warehouse.
The entrance had a single light swinging in the wind casting wicked shadows against the rusted wall. A batarang later and the warehouse was cast in safe darkness, a place Bruce had taught him to feel at ease in.
Robin slowly opened the door to the warehouse office, avoiding the large shipping doors for fear it would be too loud and attract too much attention. Normally he'd go for a window instead, but unfortunately the warehouse didn't have any. Stepping into the warehouse office he saw that is was covered in the normal fare of paperwork and coffee mugs, nothing out of the ordinary. The door leading from the office to the warehouse floor was slightly ajar, making Robin's heart skip a beat, but then he smiled and shook his head.
'Letting shadows and boogie men scare you, wouldn't Bruce be proud.' He thought.
Keeping crouched, he slowly opened the second door, and his pulse spiked when he heard a trip wire snap on the other side of the door. He looked up and just above the door frame on the other side was a spray nozzle that coated him in thick deep green gas.
Robin coughed sharply as his vision went hazy and reached for his utility belt, but his hand felt numb and heavy, falling to his side. He fell to the ground with a heavy thud and looked up to see the Joker standing above him, grinning ear to ear.
"Well I was hoping to catch a bat with my trap, but I'll take a bird boi any day! AHAHAHAHAHA!" He laughed insanely. It was the last thing Robin heard before falling unconscious.

Consciousness returned to Robin slowly and the first thing he sensed was cold surrounding him. He slowly opened his eyes and found himself no longer in the warehouse. Instead it looked more like a hospital or some kind of medical examination room. He felt air blow across his body and he realized his was stark naked and shaved smooth from the neck down. Even his balls and ass were shaved, leaving his skin exposed and stark.
A chuckle snapped Robin's attention to his right side and he saw the Joker looking at him with insane eyes. The Joker was dressed in deep purple doctor scrubs with a surgical mask hiding his face. He pulled the mask off and took Robin's chin in his fist.
"Glad you finally woke up bird boi. I was afraid you'd sleep through all the fun!" Joker teased.
"What have you done to me!?" Robin almost shrieked.
"Oh that?" Joker pointed out as he rubbed Robin's silky smooth thigh. "That's phase one of my plan."
"You know he'll stop you!" Robin threatened, hoping to stall the mad criminal.
"Oh you're right, he might find you using that GPS in your utility belt, or your radio, or the hand full of other tracking devices he left on you. It's enough to make someone paranoid if you ask me." Joker mused.
"Good thing I dumped all of your belongings on the other side of the city. So unless you swallowed a Garman before going out tonight, it's going to be a while before he finds you. AHAHAHAHAHA." Joker laughed, feeling totally in control.
