The when and how One takes the desision to go with his brothers and leave Draxum

When did Oneion or One I guess learn about the fusion from Sprout or Poptart. Like obviously I mean like past Oneion. (If this is spoilers for something your planning IGNORE IT!)

there's no Huge Event or anything, is just pretty much a One dropped by to hang out with Poptart and Toast was there <-this counts for both One and Oneion on the past

We did had an idea of Oneion, now grown up, seeing Toast for the first time in years and not recognizing them for a second, slamming them to the ground cause ???? who are you???

but it's debatable if thats "canon" or not lmao

[separatedleoau]

[blackstar5078-art]

Heeey, so things have been crazy on my end, but I'm making this now and that's the important part 👍

Have big @weeklymagmas post upon ya! I'll divide it nicely though, since I'm not just posting about one WM this time.

---

The Weekly Magma Discord organized a Secret Santa! My SS was @pvtpunsart and I drew Racer Donnie with a very curious purple Zafara for him! It was very fun to do 💖

---

The WM previous to the most recent one had Paranormal Activity as it's theme, and again, things got so crazy on my end that I only did one doodle on a mini-collab kdjsndks.

The mini-collab of Bonnie doing a class about cryptids by @autisticartistnauthor, I had to join the silly. Here is my AU Donnie with the lineart layer actually where it's supposed to be this time (ty Magma for that...). This is moreso a prototype of his civilian design, it's not final, the only thing final here are the marks under his eyes (with his sus look he looks a bit emo here lmao).

---

NOW we are talking about this weekend's Magma, Fanworks Fanart, and boy oh boy, I was on a mission to do as many drawings as I could (and surpass the 6 drawings I did on my first Magma).

I started off by drawing One by @dianagj-art. Amo mucho a este bastardo, he had to be first.

I followed by making fan art of a fic that I have not finished yet, but I'm enjoying so much that I had to. This is The Foundation by LotusFlair.

We have Bonnie! >:D By @autisticartistnauthor. I wanted to draw him for so long and I think the hands forming a triangle shot from the show it's so iconic.

By the time I started drawing him, I didn't spot Poptart anywhere on the Magma pages yet, so I decided it was his turn. Love the silly by @intotheelliwoods <3

Then I chose to be evil. This is Bad Future Donnie from The Forgotten Time AU by @vacillant-feline. This is a reference to the animatic, you know... the one. (I love it so much, I rewatched it multiple times).

Back to silly, it's Tiz Sep AU Leo by @tizeline! I seriously love so much how he is canonically a Shadow fan, I gave him a big plushie to support his hyperfix.

It's more Tiz Sep AU because I couldn't stay silly forever. I love the beef these two have, I wanted to portray two kinds of anger here <3

And the final piece I got to do before I got summoned by my friends. I had, but seriously, had to include fan art for my favorite fic of all time, I May Be Invisible But I Still Look Good by @dandylovesturtles. I improvised the heck out of the poses and how to represent the three senses, ngl, but I'm happy with the result!

And that is it, 8 drawings!! I'm very glad, since I actually will not be able to join the Magma pages for the upcoming three weekends. I'm going on vacation this saturday and I will not be back home until the 28th. I will try to do some doodles on my sketchbook related to the upcoming themes and posting them on the Discord! You can't keep me completely away, I love drawing and hanging out sessions <3

I love your comics and have been looking at them for a while, but no matter what I do I can't seem to find what happens when Leo meets Splinter.

Idk if you don't want to show it yet and you are waiting till later in the series, but I'm curious what would happen? 🧐🤨

there's some info about that linked on the pinned post!

[sc6rl3t]

Close ups from @pvtpunsart 's amazing magma sesion it was amazing and i love all of the art that has made and thank you for your amazing lightning and magma sesion @pvtpunsart

The theme was aus but i can only draw leo and mikey so you guys get leo and mikey (for now) also sorry raph forgot to draw the pizza box

[separatedleoau]

So, I’ve been wondering- well- it’s a few questions actually- hope you don’t mind- but: 1: How did you come up with the idea? Like, did you just wake up one day and go, “heh, Leo but he was raised by Draxum,” or did you see an episode and wondered, “oh, what if…”. 2: How long had you been drawing the turtles? Because holy truffle Mac’n’cheese the art style is just BEAUTIFUL- and the little animations/gifs you make- CHEFS KISS 10 FOLD! 3: And finally, who is your favorite turtle?

it was one of those cases where you turn into Thanos going "fine I'll do it myself" because I was reading a few separated au fanfics and there was a specific one where I really felt like they were not using "Leo raised by Draxum" at it's full potential to the point it became very frustrating to me, I also had that introduction scene stuck in my head with One dropping down in front of the other turtles that I had to draw it because I didn't see anyone else doing it like that

not that long really, all the hype around the movie is what got me to watch the series and it wasn't until I got really obssesed with Future-Leo-time-travels-to-the-past AUs and separated AUs that I started drawing the turtles. also thank you!!

from an outsider's perspective aka before I watched the series and knew anything tmnt related stuff, Mikey always seemed the most fun. Watching rise it it turned out that I love all of them, it really depends from episode to episode I guess, but Donnie stood out the most to me. But since starting the sep Leo au... Leo, is Leo, most specifically One, I love my boy

[intotheelliwoods]

We usually see the besties interact in the 2AL world - but we also see Sprout go to Oneion's timeline so presumably it's not that they _have_ to meet in 2AL.

What do Sprout and Poptart know about One's timeline? Have they been? Does One tell them anything about what he's been up to, any recreational criminal activity or...?

Poptart has only rarely been to Ones timeline, he goes over more frequently when One starts to live with his brothers, but I think the 2AL place is just more of a favored place to chill!

One meanwhile rarely, if ever, tells them what he is up too

Everything Poptart knows about One and his timeline, he found out about either by himself, asking questions, or accidentally (the vine situation for example, Poptart learned through an accident)

Everything Sprout knows meanwhile, was told to him through Oneion, who is way more open about everything. Sprout then would often have to keep what he knows from Poptart until Poptart finds out for himself through One... somehow....

If this question is a spoiler please do not answer it, If this question is a spoiler please do not answer it, If this question is a spoiler, it is not necessary to answer it, although it is not so much a question? I have noticed that Leo has very idealized Draxum for being his creator, how he clings to the prophecy and how He gets upset when people question him, I was wondering what the biggest possibility is for Leo to "redeem" himself for his brothers? Because of Splinter? Or because Draxum made a mistake in the end? If you can't answer this question, just tell me if If you consider Leo as evil or as just someone who follows orders and that's it.

Oh yes! One certainly has Draxum up in a pedestal, and is gonna be very hard for him to take down that from there.

For him, Draxum cannot be wrong, One's whole existence is attached to Draxum and his cause, so he can't be wrong about it. In a way One's mentality with Draxum is still like a little kid whose whole world is their parents and will take everything they say as the truth, no questions asked. Draxum is always right. Draxum cannot be wrong.

now this is spoilers so I'll be vague about it

so the time will come when Draxum gives One a mission that doesn't feel right to him, that is plain up wrong. but it can't be wrong because Draxum has never been wrong about anything, has he?

it'll lead to One having to take a decision for his own instead of just following orders <- seeing this is what makes his brother fully see that there's good in One, is not just wishful thinking on their part and hoping he's not plain evil

as for if he's just following orders or if he's evil? I think a bit of both. this is not black and white. One has done and will continue to do awful things, sure, he does them cause it comes with following orders, but he truly enjoys it and will sometimes find the way to be cruel even when it wasn’t needed

some of that will change, some of it will not
