I'm sticking to my Mila fan theory connection to cover that. I think he should come back to win DOA6.
tengu is fan fiction. no but seriously, I see it as entirely plausible, nothing in DOA says no to it, and it works, so I'm sticking to it so long as it still works.
plenty of ways. mist goes after him to use as the next human weapon, that or I imagine him sitting in the middle of the desert, just him, in a recliner, with a beer, a lamp, and a lone tv in front of him, coming across DOA tournament while channel surfing.
well, it is a televised global event lol.
But that's like me saying that this whole time Marie Rose was the leader of MIST and all of Fame's other children (Kokoro, Eliot, Kasumi, Rig, Helena, Marie Rose and Leifang) are actually spies who were sent out by Donovan, who is actually Fame Douglas resurrected, to gather intel so that he can create the sexiest bikini to sell as DLC. I mean, nothing in DOA says no to it, so it works.
except that's a huge stretch, while simply saying Milas mom was Lauren, however, isnt a big stretch at all. plus my idea gives Leon more reason to be involved and have a character relationship beyond "Bayman doesn't like him". also yes, many things in DOA say no to your post lol. like how we know who kasumis parents are, and Donovan and Fame were around at the same time, etc.
And thus, Donovan's biological uncle.
