#since its established the chaos emeralds have both positive and negative energies

Also, pondering... Super Sonic variants

Curious

How would the shards of chaos interact with other power-infused gems? (Chaos emeralds, Sol emeralds, Warp topaz, etc.)

Also, what do they do? Are they like a ripoff Chaos emerald type deal (super form, chaos control, etc.), or something different?

So sorry for the mini essay coming your way

Essentially the most important part to remember about the shards of chaos is that while the chaos emeralds are positive, the shards are negative. But they do work differently in certain ways because of this. (Gonna answer the questions in reverse.) It isn't exactly known the one purpose of the shards' existence (not just because I didn't know, for real this time XD) but they do carry a dangerous amount of negative power/energy. They sort of have minds of their own (a hivemind, if you will....wink wink) and can use their power to corrupt a host/user for their usage (but WHO they can corrupt is pretty specific, as said host needs to have an established connection to them.) All they really want is chaos and destruction by instinct. Through a user, they are capable of teleportation, which I guess you could say is like chaos control, yeah. They don't grant a super form when all seven are used, but rather, something else in which full corruption and control is gained by the shards over the user (think Terios' Doom Form.) Doleon, the first one to gain that connection to all seven, is able to do multiple strange things with their power too, as he has already been corrupted for centuries. The more the host is corrupted, the more power they are able to use.

As for how they would interact with the other gems? I'd say...

Chaos Emeralds ≈ Shards of Chaos. They seemingly have the same INSANE amount of power, just with opposing energies. the idea for the shards actually did come from a weird "what if the chaos emeralds, but evil" concept I had thought about once XD)

The Sol Emeralds are essentially the Sol dimension counterpart to the Chaos Emeralds, so I don't think the interaction would be much different.

Warp Topaz < Shards of Chaos. The Shards can't necessarily undo or stop its effects or anything, but they do hold more power. On the Sonic wiki, it says that "The Warp Topaz does not seem to tolerate anything that is more powerful than it, such as the seven Chaos Emeralds. If subjected to such power sources, it will begin to absorb their energy and spin out of control. Such power has been proven to cause a powerful explosion and even cause a rift that sends users to different dimensions." So I'd think the same would apply with the shards, but since the energy types are so different, I actually don't know whether or not the results would be different?

Phantom Ruby ??? Shards of Chaos. Both strange gems with strange energies with the full capabilities unknown. All I can say about this one is that a battle between the two users would be cool as hell.
