My random sketchs

In my previous pieces with Twisted Dyle, his eyes are lifeless looking. This is an indicator of how much control he has over himself while twisted. The more lifeless they are, the more twisted he is, which means he usually follows his instincts. When Dyle twists, he dissociates. He's aware, but doesn't usually care to stop what his body is doing (emphasis on usually is important here). For him, his twisted form is his way of processing his day to day stress from keeping Gardenview afloat after the shutdown. He only twisted a couple times before the shutdown. He also has very high sensitivity to sound which is what causes him to snap when he hears something loud, like failed machines, airhorns, or Pebble's barks. I think overstimulation is the best way i can put it, except he lashes out in response to it instead of shutting down.

I also headcanon that Dyle was the first ever toon to twist, however since he was kept in isolation, nobody knew it even happened. I believe that after he spoke with Arthur and Delilah about appearing on the show after the transcript, he was still denied, and he was devastated about it. That devastation twisted into anguish and envy, and that was what caused him to twist. He destroyed the posters on his floor in a rampage, getting ichor everywhere. After he calmed down and untwisted, i imagine he may have tried at least cleaning the ichor up that was on the floor but couldn't clean it thoroughly for some reason (maybe lack of proper cleaning supplies for it) which left it as the faded stains we see on his floor now.

Back to the topic tho, his eyes are more lifelike here because he's in full control. In this case he was stressed and scared, not angry. In the timeline at this time, this would only be Dyle's second time twisting. Astro found him hiding by the train tracks.

Now my Astro headcanons (and partially his canons) play an important part here. Astro can sense when toons are dreaming, however to enter or manipulate their dreams, he would have to get pretty close to them for a stronger connection.

He could always sense every toon when they dream, no matter where he is or where they are as well as the type of dream they're having. This means he could also sense Dyle's dreams. That's how Astro knew he has existed the whole time, however he was unreachable. Dyle often has nightmares, especially nightmares from when he twisted the first time. Astro could sense his stress when he's having those dreams but he can't help him because he doesn't know how to reach him. Even when Dyle isn't having nightmares, his other dreams are often about being on the show with the other toons. These dreams radiate his lonliness which Astro can sense too.

In this case, when Dyle left his floor to hide, he was trying to hide from Delilah. The day was much busier than normal and Dyle was struggling to keep up. He got overwhelmed and twisted that way. They do have an automatic system for the trains, but it's only set up when absolutely necessary. Dyle set it up to give himself a break, but the automatic system is very easily noticeable from the manual one by the higher ups (early technology for such systems so not the greatest), and the day was important so Delilah got frustrated and went to talk with him. He didn't want her finding him in his twisted form so he left his floor and hid himself by the tracks, sticking to the darker areas and using his ichor to hide himself better incase they looked at the cameras. Yes the tracks have cameras, mostly by the stations though so Dyle can control when the trains depart, but some are scattered along the rest of the tracks just to make sure they are going the right ways and nothing goes wrong. He knows how to avoid them though, he knows them like the back of his hand.

At one point, he fell asleep, and began dreaming, so Astro knew where he was, and this time he could be reached, so he went to meet him formally, only to find him twisted. However he could tell it was extreme stress and Dyle was scared. He didn't understand what a twisted was at this time because this was before The Incident. Dyle woke up, Astro didn't run away. Dyle was also entirely coiled up so he didn't look as big as he actually was. His arms were both tucked in and covered by his tail, and his mouth partially hidden by his tail too, so the fangs weren't visible and he wasn't as scary looking despite his appearance and size. Astro offered him comfort and began helping him calm down. At one point Astro did ask for one of his hands, and Dyle gave it to him, giving permission to be touched. The claws caught him off guard but they were relaxed. Astro continued soothing him until he untwisted, which came as a shock to Astro cuz now he knows Dyle wasn't supposed to look like that. They talk and introduce themselves to eachother.
