Already sounds better than the usual clone stories that DOA is having issues to get rid of because they can't seem to come up with an interesting story in general lol
They should just go full dumb with it; there are only so many times the "DOATEC has kidnapped (inset ninja here) to build the perfect fighter" card can be pulled, I say in the next game DOATEC has built a time machine to pull DNA from fighters from multiple timelines and only the ones that can stop them are the Mugen Tenshin Clan! stupid? yes, but it'd be entertaining
and of course this would be happening during the DOA torunament so the regulars who show up would also get caught in the time travel shenanigans, and we'd get to see match ups like Hitomi vs a young version of her father, or Jann Lee vs the real Bruce Lee, and other ridiculous scenarios
