@Ghid It is quite unfortunate but true.
@The_Blue_Panda If not me, someone else will cap off the year with bats. 
Thanks!
@Rhyla416 Thanks as well.
@DuneToa For a short answer, I will say that it would be more accurate to describe Bumbleberry and her siblings as cyborgs or biomechanical. At least in universe.
That’s not what a TLR character construct is and probably should have just stated the cyborg clarification…so if you want a somewhat comprehensible explanation of author nonsense, here you go.
Too meta for my own good.
In brief, I look at the metaphysics (for lack of a better term) of fiction differently than most people. If a setting has a multiverse, most fans tend to believe that their works exist within that multiverse. Perhaps not in an official or legal capacity, but that the canon of how multiversal/alternate dimensions/etc. functions technically means they exist from an in-universe perspective. Somewhere in that infinite possibilities is their work, even if never visited.
I, however, don’t believe that to be the case. I believe that, instead, a copy of the multiverse is created and exists outside of the canonical multiverse and are unable to interact with the original. These copy universes (or multiverses) are created by Author characters.
Author characters (or forces) are in-universe background/meta explanations for how the universe is created. They are author stand-ins, but on a higher level. Think something similar to Marvel Comic’s One-Above-All, which is an in-universe representation of all those who collectively worked on Marvel Comics and essentially created the Marvel Universe, but also exists outside of it. It is neither literally the author, the person writing the story in real life, nor the narrative within the fiction for how things were created, but something between. Something all powerful within the fictional worlds they create, but unable to do anything to worlds they did not create. Hence the copy multiverses.
My Author character is The Lego Roleplayer*. Roleplays, especially GM-less open sandbox RPs, tend to be the weirdest fiction realms. It’s a place where rarely any one Author has full control and plenty of Authors can edit the universe, or at least insert characters, forces, etc. that can. And this is where we get into Constructs.
“I am merely a Construct, an imaginary intimation given form and life.”
How TLR functions is that he tends to create/perform three different actions: Creation, Disguise, and Construct. Creation types are bring/making something for a particular universe; they are the original. Disguises are weaker Constructs that TLR inhabits when participating in RPs himself; basically an actor in costume. And Constructs are copies, imitations of his Creations.
Rather than sending his original characters into a game, and thus avoid having to reconcile narrative reasons for why they were there or add unwanted canon to said characters, he creates a copy - a puppeted automaton. These Constructs, like Creations, can become any form of existence (matter, energy, spiritual, magical, etc.).
These sorts of distinguishments came about as a result to solve some other meta narrative paradoxs I wrote myself into. So it is incredibly silly and convoluted, but hopefully it makes some sense.
So to explain the context of Bumbleberry more plainly, let me say it this way. TLR has been contacted by someone else on the boards. That isn’t just flavor text, he is really responding to someone and it is bat/bug related. And because he has been given an invitation, plus the allowance for one to make batgirls in general, he has answered this call and created Bumbleberry and her siblings. Yet rather than send in his Creation, he is giving a copy (character Construct) as that will be easier to erase. And it won’t do any actual harm to the real one, should his contact do what they claim. It being a Construct will also allow said contact to control them and “flip their switch.”
You’re more than welcome to guess who TLR has been speaking with, but good luck figuring that out.
*I also tend to use TheLegoRoleplayer, or some variation, elsewhere online. But TLR the character and TLR as in me the person are two separate entities. I didn’t think about the problem that would cause, due to how infrequent it comes up.
