Something I noticed/ Act 2 theory
so I was rewatching to crk act 2 trailer W.I.P and it got to the part where we see like the dragons and corrupted gaurdians and that stuff but..
I was looking at this frame and...
WHO TF IS THIS GUY???? and why are they glareing at the others
At first I thought it could be "ebony dragon" that obscure Umbra cookie in ovenbreak talkis about but there are a few issues with that. The color asociated with the ebony dragon is a shade of crimson and they haven't actually been seen in OB yet. I don't think devsisters would show them off in a CRK trailer befor showing them in OB.
so uh who is this? well I have a theory, so far we have had it so that each ancient/area get their own respective segment each major plotline. and I dont think thats changeing since the trailer shows three groups of cookies and then smilk. why am I mentioning this? well...
I think this might have some connection to or could BE dark cacao cookie
obvious one out of the way first his awakend form is literally dragon lord, and he is closely tied to the white and black dragons
while all the ancient cookies show pupils when emotional (hell PV even gets small slit pupils though I think it's due to the pupils streaching with his eyes which Dark caca's don't) Dark cacao's are notable because they are full slits, they also are not the only set of pupils he has as in one of his sprites, he has normal rounded ones, In the angry sprite he also has a shadow around his head which resembels pitayas transform sprites.
Dark cacao's design also has quite a few physical resemblences to the mystery dragon espiceally in the title screen for the Heros of Dark Cacao update
he has almost the same eyes, the horn on the dragon resembles the front of his crown, they have similar hair and their signature color is purple. Longan Dragon would also HATE the fact that a mere cookie would dare be called "Dragon lord" and the fact that he "defeated" the white and black dragons.
TLDR dark cacao is or has some sort of connection to the mystery dragon
