Copy is an Emitter-only type. Speaking in a way to understand, when the user of Copy touches a person, it only emits a replica of sorts of the quirk. One way to say it is that it takes what is there, and only physically emits itself onto it's user. Sorry if that was hard to understand.

One For All is a mixture created by All For One. It is described that All For One had unified a quirk that can pass on from one person to another with a quirk that stockpiles power, which is why One For All gets stronger every time it is passed along. So it's not really a hybrid, just a mixed Emitter power which is just like Half-Cold Half-Hot, just that instead of being combined genetically, it was mutated through All For One.

All For One is an Emitter, can't really be Transformation or Mutation. It's just a more advanced version of Copy, being able to take the power completely and own it for yourself. Because a quirk is just an extension to yourself, that's why people go into a comatose-like state, because that extension is so much of themselves that it destroys them mentally.

Shock Absorption is said to be a Mutant ability, but it seems more like an Emitter ability. I think this because people can have certain forms of character but, doesn't mean their quirk is related. If it was a Mutant ability, the Shock Absorption wouldn't be limited to how much impact it could absorb, that seems more like an Emitter's weakness. I believe the quirk is simply a defensive barrier to the body that has properties of a Mutant quirk to be active on it's own, but it's barrier can be broken down if you break the limit to how much it can absorb.

Warp Gate is an Emitter type. He's not transforming his body, he's simply hiding it under the dark fog. He's only creating the fog. What mainly makes it Emitter is how it must be used. Warp Gate requires coordinates. He doesn't make Warp Gates based on where people are, but where he wants them to open. If he wants to create a Warp Gate directly to his partner, he must focus on the place they're located, not on the partner themselves.

Tape is said to be an Emitter type, but I feel like it's more than that. Hanta Sero (User of Tape) has the Emitter weakness of not being able to overeject his tape or he'll suffer dry skin. But, that doesn't take away the fact that his elbows are created exactly for the purpose of shooting tape. So, I honestly think it might just be a quirk mutation of one person who can summon tape with a person who's quirk relies on their elbows. (Even though that second quirk kinda sounds weird)

Dark Shadow is said to be Transformation, and it shares the properties of one. But what's strange is that it also shares properties of Emitters and Mutants. What makes it similar to Transformation is that it's not just there, it's like a soldier, it takes commands but has a mind of it's own. What makes it like a Mutant ability is that when summoning it, it isn't capable of actually detaching from his body, it's just an extension to him. What makes it similar to Emitter is that when in the darkness, when the shadow becomes most powerful and extremely vicious, he has to focus completely in order to control it. I know the idea of focusing seems like something least likely because it clearly takes some focus to be able to use non-Emitter abilities like Earphone Jack, but I only took into consideration of focus because Izuku has the exact same problem when learning to control his power. Either by focusing extremely hard or naturally when attacking people, Izuku was sometimes able to stop himself from breaking his body, similar to Dark Shadow, just not 100% the same. So ultimately, I think Dark Shadow is either on a class of its own, or it's actually just a mutation of all 3 classes.
