After we get the Kefka ultimate, we should get an Ultimate where we fight against (or with) all the trains we have met so far.

There's the Phantom Train from Sigmascape 1.0.

The Doomtrain from the recent Dawntrail trial.

The Tower of Babil dungeon starts on a supply train.

And also there's the train we used to breach into Solution Nine during the Dawntrail MSQ.

I might be missing even more trains.

I think that can be a really well made ultimate that is loved by fans, and we now know it's possible since Kefka Ultimate doesn't really follow the usual pattern of ultimates we see.
