I do not own Mortal Kombat Armageddon, for a variety of reasons, but recently i thought of something that might be interesting: Taven's face dragon tatoo is surely based on the facial tatoos that the Black Dragon Grandmasters had in Mortal Kombat Conquest.
I mean...
Taven from Mortal Kombat Armageddon (Daegon's facial tatoo is similar, but on the other side of his face)
Bannak (former Grandmaster of the Black Dragon clan)
from Mortal Kombat Conquest
And Kebral (Bannak's son, and leader of the clan after his father's death)
This is quite strange, because Daegon also has this kind of facial tatoo, and yet he formed the Red Dragon Clan, plus is and always was the Red Dragon Clan's Grandmaster, while Bannak and Kebral, though non-canonical MK characters, were both Grandmasters of the Black Dragon Clan centuries ago.
Maybe Midway used these tatoos in Armageddon as a homage to the series... or maybe not (most probably not).
