I love creature design and speculative biology so of course if you give me an alien that looks human I'm gonna be sad about the missed opportunity- But I can create my own opportunities so first I needed to figure out how to draw Clark's face (took forever, used to round faces with less distinct jaws) Once I did that (ironically on a drawing that was Clark mixed with a DIFFERENT creature) I was unstoppable.

So Kryptonians have a mixture of bird human anatomy- while Clark does pass as human there are still little details that visibly show that people either shrug off and don't notice/ask about- or he actively hides (and he had to unlearn this- I see the leftmost superman as him when he first started and the middle one as when he got more comfortable with being openly alien thus exposing his more alien features (his feet) Anatomy details

He has a bird crop. His has different internal organs then humans and it shows most here- though he hides it by just keeping his crop empty, which makes it look like the middle superman. It's much smaller empty and thus people shrug it off usually

His shoulders are pulled back a bit due to his keel and huge pecs, his shoulder rotation is different then a humans, as human arm rotation evolved for swinging while Kryptonian ancestors were evolved for gliding. He still has enough arm rotation to mostly mask it (as from what I see birds do still have decent arm rotation for flight) but if asked to do something he can't he'll say he's not flexible enough (technically true) or find some other excuse Fun fact, he also isn't good at aiming. He can throw with all his strength but he's much more likely to miss the target then a human will)

Looking at bird anatomy the pecs seem to take up a large portion of the chest and torso, which ironically made Clark's less noticeable since his stomach and abs were less visible granting no contrast

His keel! His keel does protrude and is noticeably different from human collarbones, to hide this as Clark Kent he wears baggy clothes

4 fingers! Birds have less digits then humans do but they still have bones that could become digits again. Kryptonian ancestors, when their arms were more like wings did have thumblike appendages, and as grabbing became more necessary for Kryptonians, prominent fingers evolved. Clark explains his 4 fingers as just being born with 4 fingers on each hand (I knew a kid born like this though she only had it on one hand)

So bird's ankles are where our knees would be on our bodies! While with Clark here it's more of an inbetween, more akin to legs of something like a cat- however unfortunately for Clark even with this inbetween that still isn't enough to mask the difference between him and humans. This causes Clark the most pain as he has to walk heel to the balls of his feet in day to day life which for Kryptonians is very unnatural. He can alleviate this by flying slightly to take pressure off his feet but there is another issue-

He has massive talons. Unfortunately, while he can wear big shoes, and does wear big shoes, they still aren't naturally fit to his feet so he has to wear his shoes with his talons constantly curled in. And he has to force his feet to do this himself as shoes wouldn't actually be able to force his feet to do this- and it causes him extreme foot pain.

I know this doesn't explain how Kryptonians evolve, or canon kryptonian details (flight, speed, strength, etc) and I do plan on expanding upon that but that's gonna be a different post cause here I was focusing 1. On bird 2. How I was making Clark different from humans beyond he has powers In the meantime while I work on that- have a meme

But hey Nighty, why is Bruce a sith?

Good question! He's not!

Bruce a few years after his parents died would go on his training montage across the galaxy, and he deliberately sought out training with dark orders, as he found the jedi order to be inflexible in order to get the job done, and believed he needed to understand all sides of things in order to accomplish his mission.

The issue is the Dark side, as I have discovered with my research, isn't just a tool to be used, it taints you, and pushes you to the worst of yourself. Bruce did not understand this when training and so was not properly wary. And nearly fell to the Dark side. It is a testament to his personal integrity, bullheadedness of Alfred (a retired Jedi), and Dick Grayson's general existence, that he did not fall.

He is however, forever tainted. As he maintains that his philosophy for his training was not wrong, but rather the naivety and foolhardiness of his youth that led to his near fall, he now practices extreme restraint when using the force and will be rarely seen doing more then the most incredibly basic of moves with the force. When not training anyway.

He doesn't have to use the red lightsabers, they are just symbolic for him and a warning for others. Also an intimidation tactic, he is still Batman.

Dick and Jason are his padawans, however it's a mutual training, they are also training him in return. While he did train with lightside orders on his rounds about the galaxy, they are still learning the lightside together, as Bruce tries to unravel the Darkside from himself.

Jason's death in this verse as you might guess, is a fall to the Darkside rather then a death- this is Jason pre-fall as Jason's death occurs MUCH later compared to his main canon counterpart. Tim joins the gang before Jason even falls!

And their species:

Bruce: Half Chagrian and half Chiss (Thomas Wayne was Chiss and Martha Kane was Chagrian)

Dick: Big Twi-lek and Pantoran mix with some Falleen blood

Jason: Zabrak all the way!

I have the other's species though I am still working on their lore! Feel free to hit me with an ask about any of the characters- including superfam! This is a superbat story. And whether I have an answer or not I'll respond with what is going on with them, or you'll help me getting thinking about that aspect of the verse and I'll brainstorm in my answer!
