I don't wanna keep making critiques to some already great work, but Juju always looked Pretty short while this Junko looks a lot taller than she does in your drawing, or maybe she has a different body type or something.
I always thought of Juju as the short chick too, but looking at her recently she's seeming pretty leggy actually. The puffy jacket makes her look wider and thus shorter and the sniper rifle completely dwarfs her. I don't think she's tall, but she's taller than I thought.
I like what I see here but retconned means retconned as somebody else in this thread said. I don't think any traits Juju had can be used for Junko.
Cee Lone Cat Mitchell pretty much only suggested the character be Chinese, use a talking sniper rifle (or Katana) and be named Juju.
Technically Junko over her is not name Juju so that's one off the list.
Second, Juju's sniper seems to be a Living Weapon in Alex's note. He also says it talks, making it very unique from other living weapons, but it seems to be more like an AI. Cee Lone wanted the gun to be a 'Skull Monster,' which seems to be his name for a Parasites, so perhaps simply making the sniper rifle a Living Weapon rather than a Parasite it'll be fine? Unlikely, they could however make the rifle not talk as that was his initial point to the character.
As for nationality, there aren't REALLY any Chinese in the Skullverse, but we know that Juju is probably from the Dragon Empire or at least descended from there. Junko clearly has some sort of other nationality, not sure exactly what it could be, although it does seem to be eastern of some sort and I'm not sure how far the scale of the Dragon Empire is (does it include the Skullgirls equivalent of India? Japan? The Philippines?
The thing is Cee Lone never had any right to claim Juju in the first place, he hardly lent any intellectual property in her conception. So I fear no matter how much she is changed it will never be enough for him. So you're probably right ArgonBern to even more of a degree then your initial comment suggested.
