Red Dragon has been plotting on the background since before MK1 events, as [MENTION=11230]Guyver Spawn[/MENTION] nicely said.
Maybe they will show now how events trend to happen, some unchanged, others the same, but now with a clear participation of the Red Dragon, as we know, an ally of Shinnok until the battle of Armageddon.
I think it would be nice, because in MK1 Black Dragon seemed to be just some tough crazy dudes. Then, with the develop of the game, we saw they were a dangerous organized crime international group.
But Red Dragon didn't gave us this sense of "oh, how they are big" until Armageddon, when we discover their leader is someone thousands of years older and with a burden that could save or destroy all reality. I mean, Mavado and Hsu Hao never gave us the security of this importance.
Should be nice, exploring them, the alliance with Shinnok, the quest, etc.
