Do her biocomputers have an Corona though or is it running completely through her emulated connection.
Do we have any information about her Shard?
Is it the same as her Father's?
In order?
We don't know. Dragon keeps her Fetus Processors hush hush given the biotinker implications, so even if they did have this effect of growing a Corona Pollentia and Gemma as she used them, it's not like she would ever talk to anyone about it.
Her power is literally "Can understand and use other parahuman tinker tech, and can copy it and make improvements on it." It's essentially a Thinker power, but practically is a Tinker power. As for the cruel irony that all Worm powers have, her power lets her literally improve and expand on all tinker tech... which she technically is herself, but of course her limitations prevent her from working on herself.
No. Richter was an AI Tinker, Dragon is a Thinker that can copy Tinker tech. Put Richter on a non-powered earth, and he could still build AI. Put Dragon on a non-powered Earth, and her power becomes literally useless.
I will correct you though that it was a ptv simulation of Eden's optimal timeline and that those weren't endbringers. They were superweapons which are far smaller and weaker than endbringers being specifically called endbringerlites because their roles were different.
I think that's really splitting hairs. The Superweapons in the interlude were optimally designed by Eden for efficiency sake and given very specific roles in what they should do. Endbringers are essentially the subconscious spawns of Eidolon's desire for worthy opponents, and the moment Scion killed Behemoth, the next set were not only tougher due to having force fields between layers, but also had a wildly different MO so Scion wouldn't be as likely to kill them.
At their core, I don't think they are completely different things, I just think they have different settings applied to them in the creation phase. Eden went for efficiency so they could fit their purpose and had the precognitive power to ensure "These things just need to be strong enough to never be defeated, powerful enough to do what I want, and I know exactly what that should be", meanwhile Eidolon subconsciously wanted monsters he could go all out on, and the Endbringers literally are set up to use all of their power in three hundred years when their wells go dry. Thus, they were modified to fit those roles. Given the new three are differently designed than the original, we know their creation is malleable. There's nothing saying Eden couldn't make a superweapon be as tough as an Endbringer, just that she didn't need them that strong.
Also narratively, it doesn't make sense for Wildbow to invent an entirely new and separate thing that has nothing to do with current elements in the story. Occam's razor would suggest the Superweapons are Endbringers rather than an entirely separate part of the Entity's toolkit.
I will say people do focus too much on the 20 count. That's just the number Eden needed in that timeline. There's trillions upon trillions of Shards. If an Endbringer is just a Shard or parts of a Shard that's connected to the world as a construct rather than to a host.. well, then there's potentially as many Endbringers/Superweapons as there are powers.
