hmm, imagine lore for this milky, what universe would he even be from? Some messed up sticknodes where everyone is grotesque monsters of edlritch nature for reasons currently unknown?

Milky comes from a universe classified as D90-RT..D1000 (Direct ninety rational testant distances of 1000. Or directly 90 units away, rationally thought to be “1000” light years away. *on a larger scale*.)

its thought to come from the 4th dimension. It produces calcium propulsion to move around at speeds greater than light. It bends space and time in order to stabilize it’s own existence throughout its own universe.

Its particularly a superior titan compared to others. It attacks by mainly using extreme milk pressure to blast on it’s opponents/prey. An alternative is to control the calcium in their bones using a form of telekinesis.
Although while it can be outmatched in speed, it cannot be outmatched mentally.
It can spot anything moving up to 1,002,540 light years per second, and can discern what methods they’re using to fight within seconds.

All of this happens in the fraction of a second. Time does not obey the same in our own universe.
