I don't normally care much for the backstory of fighting games, but I thought it was interesting to have an antagonist who's simply "playing to win". However, that seemed somewhat poorly defined here, with Menelker being said to use tactics that are "dishonourable" or "cheap": those only make sense in context of a code of honour or fairness, which isn't really established in the setting. It seems that pulling lightning out of your arse, being a giant made of stone, screwing around with the fabric of time, or turning into a mean green dragon are all fair game - but turning into a slightly meaner black dragon is somehow completely out of line? How is that supposed to work? Is there some other source to his cheapness I'm unaware of?
