yeah i was just wondering what happened to the previous booster blue, gold, green, black, and red i know the boosters will die but what will happen to the dragons, my guess is that their dragons, conner breed beau back into existence how did he do it, i mean he can't just breed him, he had to have so Gold DNA to bringhime back and what about the other booster dragons do they just fade away when they grow old, you guys get what am saying?
I understand what your saying, I've been wondering something somewhere in that line as well. Good question, but I can't answer it sorry.:)
Except for Libris, the few indications they've given us tend to say that dragons have something similar to a human life span. Therefore all the original boosters and their dragons are long gone. Hopefully, they all enjoyed a pleasant and well deserved retirement. :)
As to where Connor got gold dragon DNA, he wouldn't have needed any specifically. From the information in the first episode, the mythology and a little more from "Chromatic Dragon", Connor bred Beau by selectively breeding dragons from all 12 colors of draconium. Properly combining all 12 colors yields gold. This isn't too far fetched if you consider that any given breed of dog differs little from wolves. The genetic differences between dogs and wolves is minuscule. So given that all the non-gold dragons were created by selectively breeding gold dragons, all of them would still be genetically very close to gold dragons. Close enough that someone who cared enough could re-create the original line (at least close enough to work within the realm of a fantasy show). :)
They don't really spell this out all that well in the story line, but I think that's how it's supposed to have worked.
It's sort of like the attempt to breed back the Auroch from cattle that are not that changed from their ancestor. The cattle that resulted were very much like aurochs, except subtly not. So maybe Beau is somewhat less powerful than the original Beau-though this doesn't make him weak at all.
