This was his response to my OC

Problem 1: Grimm hybrid. This is, with no reservations, the single most hated and most ludicrously impossible thing you can do with a RWBY OC. Why? Well, for one, Grimm are by nature antithetical to humans. They are everything we are not; mindless, insubstantial, and eldritch. They lack a truly solid body, simply ceasing to exist upon death. It would be impossible to extract a genetic sample (assuming they even have DNA to begin with) to create any sort of hybrid.

The only proper experiments we have seen to modify Grimm by humans were in Grimm eclipse; and those were mutations of grimm themselves, stronger but still inherently the same. Before you argue for the Cinder bug thing; Salem created it, and is definitely NOT playing by the same rules as everyone else.

Problem 2: Dust "hybrid" Dust isn't an organic material, you cannot make a living thing which is truly part dust. You can infuse it into a living body, but it is an embedded tool or fuel source; not an intrinsic part of their being. It is a resource that is used up over time like any other.

Problem 3: Weapon. The... "weapon" and I hesitate to call it that, is not possible in the setting of RWBY. All weapons are purely technological and mechanical in nature. They are machines and tools in the most literal sense, they function on an entirely mechanical level. The guns expend bullets, have barrels, firing pins, and triggers. They transform by utilizing mechanical components which re-arrange themselves into new shapes based on physical components. To quote Full Metal Alchemist; you can change the shape, but you cannot make it any bigger or smaller.

You can fold the pieces to take up less space, you can organize them into different functional forms, but they don't magically shrink and grow. The thing you have designed might work in other anime, manga, shows, etc; but RWBY technology doesn't work by the rules of magic. It works by the same gears, circuits, and physical mechanics that those in our world do. Even characters like Qrow and Raven who appear to have some sort of magical abilities (the bird thing) use weapons which follow those rules. Hell, Qrow's scythe is clockwork.

Problem 4: name. Three words; color naming rule. Majora is not a color, it is linked to colors but the entity, the demon, the game it exists in, are not things in Remnant. As for Solaris... BARELY scrapes by, in that it is a real word. As for the source you drew from, well.

Sonic '06 is the single most despised game in a series which is already notorious for being of at best questionable quality in most instances. The pure, unadulterated awfulness seeps through into the abomination you have unleashed. It defies all logic and established rules of the world, seemingly going out of its way to break every unspoken rule of good taste in character design.

Problem 5: "faunus" status. He's not a faunus. He's not anything. Faunus, for one, are real animals. Fish, snakes, birds, chameleons, cats, rabbits, dogs, wolves. They are not mythical creatures; and believe me I've had this discussion with people before. Assuming, for a moment, that it wasn't utterly impossible for him to be a grimm hybrid, nobody would EVER believe he is a faunus to begin with; the wings (and having wings is yet another issue) are blatantly not natural. The minute anyone saw them they'd have him locked up and shipped off to some government lab to try and figure out what the hell is wrong with him.

And you can't hide something like that. Wings are big, they're bulky, they'd pretty obviously bulge out from his back in the best of scenarios, meaning he could not wear any clothes that didn't make him look like a reject from The Matrix without drawing attention.

On top of that, if he kept them regularly hidden (and he would have to keep them concealed literally constantly to avoid detection, good luck taking a shower or changing clothes. Dude probably smells like a month old outhouse.) the muscles in them would undergo this process called Atrophy; the muscles would shrivel up due to disuse the same way a paraplegic's limbs lose muscle mass due to lack of use. They would also cramp up constantly from being in a restricted state leading to pain and discomfort.

You did make provision for him flying to natural hot springs, buuuuuut... those are pretty rare. Like, incredibly rare. Know why? Volcanoes. See, they can't just form anywhere; they are the result of subtereanean water sources being in proximity, or even direct contact with, the extreme temperatures of underground lava tubes connected to volcanic activity. In addition, a strong majority of these hot springs are too hot for a human of any variety to enter without being boiled alive. Wings also don't work in water the way you seem to think they do. Birds which feed on fish fold their wings close to their bodies when they submerge, as the large surface area and friction they provide, which is ideal for enabling flight, is a detriment in water. He can't simply "swoop through the water" to get clean. As you may have noticed from personal experience, hot water isn't enough to get all the oil and dirt off of your skin. You HAVE to use soap.

What else... ah, yes. In order for a human being with wings to achieve flight, they would need a wing span of ~20 feet. Bare minimum, Good luck trying to hide 20 feet of wings, buddy.

His skeleton would also need to be completely hollow, which would make his bones incredibly fragile. He would suffer from several detrimental health issues as his body would not be able to produce enough red blood cells to function properly, and the extra muscles would vastly increase his nutritional needs.

The rather substantial increase to body mass, extra tissue that his body would need to supply with blood, means either his heart would need to be larger or pump faster; putting him at MASSIVE risk for hypertension and heart attack. If it were larger, he would have reduced space in his body for his lungs and other vital organs. (Oh, and increased body temperature causes a further increase to heart rate as your body pumps the blood through your body faster in order to let the excess heat diffuse out of your skin, further increasing the problems of high blood pressure and potential heart attack.)
