Here's some brains and brawn chilling after working on the Shellraiser, Raph is convincing Donnie to make the truck more deadly, with laser cannons and saws ( Donnie is seriously considering it )

I am SO interested in learning about mad scientist Donnie. Do you plan on writing for him? Like his slow decent into madness after Timothy mutates? 👀👀👀

Oh mi gosh! I can't believe someone is interested in my AU stuff. Thanks for asking!!
Okay, so I will try to make this semi coherent—
*Puts on Yapping glasses*
Mad Scientist Donatello
I thought of Mad Scientist Donatello as I was planning out the arcs for my very self-indulgent OC, Maxine Santos, and the fanfic I'm writing for her. Since I don’t think there is much interest in OC x Cannon, I will likely not post the actual writing— unless I make a drabble just for him— but I can tell you more about him!
More info under the cut, line thingy?
Okay, so one thing that I feel is never properly addressed in the show is the whole Pulverizer/Timothy/Mutagen Man arc. While those 3 episodes are executed masterfully in my opinion and fulfill their narrative purpose, afterward, it's just... abandoned by the show? Everybody just forgets about poor Timothy's existence.
I always thought that was odd and that Timothy's mutation should have a heavier narrative weight on the story, especially on Donatello, since he feels personally responsible for the kid ending up as a blob of acidic mutant goo, so I really like imagining different scenarios for how this would affect Donatello.
The idea is that after some time traveling shenanigans from the Kraang and the turtle's interference, they accidentally create several "bad ending" style timelines for the turtles, each with a different twist, zombie apocalypse, Kraang empire, Footclan!Leonardo, and so on. Since my OC, Maxine, was the one to get caught in the crossfire, Renet— the time master assistant— is the one who requests her help to save those timelines before they become "fixed" and cannot be changed anymore.
In this specific timeline, Timothy actually becomes the second human ally for the turtles— the first being April, of course— because even though they think he is a massive dork, he keeps getting himself into trouble and the turtles have to save his butt every time. But!! Eventually, they create a friendship of sorts, they find out more about Timothy's life, and there's some angst, I haven't decided exactly what yet, but it explains why Timothy is trying to live in fantasy land and play vigilante.
So they have this sorta awkward friendship, and Timothy eventually does start to help out in missions, not physically, but he helps the turtles investigate things that they can't, such as gather intel from other humans, investigate weird stuff happening at the local high-school, and he is a very good gamer, so he controls metalhead before Donnie creates his AI— and he's pretty good at it!
Things are going pretty well for a while until Donatello gets kidnapped by the foot clan, and they're planning on dunking him in a vat of mutagen because evil ninja clan shenanigans.
Despite the other brother's warnings, Timothy follows them because he wants to help Don, things happen, and instead of Donnie getting mutated, Timothy does.
Donatello is overcome with guilt because he is the closest to Timothy, and that's what lays out the groundwork for his madness. He starts obsessing with finding the retromutagen, and every new bad thing that happens keeps pilling up on that until it breaks the cammel's back.
Then Kirby O'Neil gets mutated and April is much meaner about it in this timeline, then they find out Karai is their sister and right after that she gets mutated and tries to kill all of them, she mutates earlier in this timeline, too, btw.
And as if that's not enough pressure on our poor boy Donatello to find the retromutagen no matter what happens, the turtles fail on a mission where the Kraang were trying to use some kind of mutagen infusor on the crust of the earth, and it gets a big part of the city mutated. Leo gets double mutated and goes insane, Master Splinter ends up extremely injured after fighting a mutated Shredder, and April and Raphael are missing. April has been kidnapped by the Kraang, and Raphael has been brainwashed by the foot clan with the brainworm.
SO, at this point, Donatello absolutely loses his shit.
He starts to experiment on Timothy, himself, and his brothers and Master Splinter, because of it, trying to find the retromutagen, but because he doesn't have April's DNA, it's a fruitless task.
Donnie is so far gone down the rabbit hole that he spends long hours down in his lab ranting to Tim about his efforts to find the retromutagen, how he's the only one who can find a cure, his crush on April becomes 10x worse because he's grasping at straws to keep going, Master Splinter has been in a coma ever since his fight with the Shredder and is in no condition to fight even if he woke up, and Leo and Mikey are constantly being experimented on, and can't do anything to save Don from himself. :(
Don is constantly hallucinating April and Tim. His hallucinations for April range from weird self-indulgent and delusional romantic scenarios to her mocking and insulting him for being a mutant, and he believes that if he finds the retromutagen then everything will be alright. His hallucinations for Tim are mostly geared towards friendly banter, with the occasional lashing out when Donatello is going through a particularly bad episode.
Don gets frequent headaches from not eating right, not sleeping right, and the constant experimentation and stress and it's just generally very angsty because I love to put this man through massive amounts of physical and psychological torture :D
Anyways, that's it— thank you so much for asking!!

Finally we have my Hamilton Au thingy with Lafayette Don and George Washington Splinter and some love for my favorite Shredder Henchman ( Xever )
No, I don't just like him because he's brazilian, hushush
His face shape is so hard to draw my god
There’s also a small Baxter Stock and a Chris Bradford that's suffering

And then we have some undertale, iscdisc was drawing some Deltarune and it awoke the sleeping beast ( I was in the Undertale fandom back at it's peak )
*shivers*
We have a Gaster Don, a MTT Don, a Frisk April, a Sand Mikey, and a random Jotaro Don poking in
Open for better quality

Aaa I participated in iscdisc's whiteboard session and it was so fun, I think I got a little bit excited 🥹 thanks for inviting me
My back is killing me but it was every bit worth it
Here's some of my tmnt bullshit
Unfortunately I can't plan my sketches for shit, I'm so sorry
First we have Donnie being a pathetic little nerd about his crush on April
We have a mad scientist Don, where he went mad after Timothy got mutated
Then we get an Echoes of a Burden!Donnie, which is my AU that I have never posted about lol
And some random Maxines poking in

I'm glad that you liked it!! It was really fun :) I love me some Donatello angst
Oh that's really good! It's pretty much cannon that most of the brothers go into a panic/don't know what to do during these high stakes situations, Raph especially :(
That scene is very well written! Could you tag me when you start posting the fanfic? I would love to read it :)

@foxtrixcore asked for a Donatello who got some kind of facial disfiguration after some fight and made himself a mask to wear, and what that mask design might look like
So here's my idea of what a partial mask cover Donnie would wear, I took some inspiration from mutant apocalypse Donnie
And bonus art

My poor baby :(
Additional thoughts:
I really like drawing/writing about Donnie getting really hurt physically. While I believe all of the 2012 turtles and Splinter know basic first aid — and Splinter for some reason knows healing magic ( or "mantras" )— I still believe that Donatello is the only one who has extensive medical knowledge and can perform surgery and treat their mutant physiology, soooo it just really scratches my brain to imagine what might happen to Donnie if he got too hurt to treat himself, since his brothers surely wouldn't be able to treat him themselves.
That also makes me think about Mutant Apocalypse Donbot in the series, is the only reason why his mind was transferred to Metalhead 2 because Raph wasn't able to treat him after his amnesia? Donbot says his original body was destroyed, which could either mean Donatello immediately died after the mutant bomb explosion, or he held on for a little longer.
While if Donnie did die immediately after the bomb there was nothing anybody could do, what if there was something that could be done? Let's say, a possible cracked shell?
Cracked shells can be lethal, but they are not always a death sentence to a turtle depending on the severity, but if they aren't treated, a turtle will bleed out or die of infection. That's to say what if after the explosion, Donnie was severely injured but could have been treated, but Raph was in almost as bad shape, and couldn't treat his brother, which is what led to Donnie's death? The angst is just so good
While Donbot doesn't seem to have any issues with the fact that the original Donatello is dead does he ever wonder what could have been if the original Donatello was treated?
Did he even try to treat the original Donatello? He seems to imply that he was already cybernetically linked when Donatello died, rather than consciously uploading his consciousness because he knew he would die, so is it fair to assume that maybe he tried to save himself— sort of like in the comics— but there was nothing that could be done? And if that wasn't possible, would he ever resent Raph? Maybe not forever, but right away? I mean imagine being the only decent doctor in your family, you save their shells for years, but when you really need it, and not a dislocated shoulder, or a sprained wrist, but really need medical help, there's no one there for you?
Anyway I loved this idea :)

Sunrise duo requested by @reapleaser
I love drawing Mikey and Leo being silly together, although Leo's face is a little bit weird in this, I find Leo's and Raph's face shapes to be the most difficult to draw, but I think Mikey turned out really well in this one, even though I had to hide some mistakes
But here they are!! Some other people requested more Leo so hopefully I will get more practice with drawing one of my favorite turtle nerds

I'm glad you liked it!
[Oh wow- little nervous because I hardly ever ask for requests lol]
Can I request my OC Nebula x 2012 Leo? Just having a wholesome little moment. Maybe Leo telling him about Space Heros because Nebula is an alien and Leo's definitely a space nerd lol.
I can dm you his ref, or you can find it through the tmnt blog in my pinned post. Up to you! ^^
Alternative option if you don't want to do the first, just 2012 Leo being a space nerd. Love his little obsession with his show.

This was really fun :)
Glad to see there are other 2012 Leo appreciators around
I also love Leo's obsession with Space Heroes, he's such a little nerd, I headcannon that he has a lot of secondhand merch from the show and comics

Calling TMNT Nerds
I draw too and I am bored.
I'm just coming out of a 7 month hiatus of not drawing every day and I need stuff to get me back into the habit, so feel free to send me a request! Bayverse, 2012 and Rise only because idk enough about the other versions or don't like them, sorry :/
Send me requests for the turtles and/or your tmnt ocs for me to draw, I will take like 3-5 requests, no deadline so feel free to send me something in my askbox or through a DM, only rules are nothing nsfw— but suggestive is fine— and no character x character shipping because the shipping in this show gives me a headache, I will do oc x character though
I will delete this post when I stop taking requests, so if you see this ask away

Soooo a friend put this image into my head, Donnie with lingerie and a maid outfit and I couldn’t get it out of my brain, he doesn't have a tumblr so I can't shame him, but he knows exactly who he is
Y'all have him to thank for this lmao
Donnie is so cute!!! I love drawing him in dresses, he's adorable when he's crossdressing
And Max is checking him out lmao
