Perhaps even more than mine.

I got a few ideas...most of them could be based on The Four Horsemen of the apocalypse (Which included death), with one being a variation of one of the horsemen.

These powers could be:

Eyes of Future War (Shōrai no Sensō Me): Causes the fighter to increase their fighting skills with rage and hatred, making almost unstoppable but overuse can lead to insanity.

Eyes of Future Disease (Shōrai no Byōki Me): Causes the fighter to infect themselves with a disease related to their clans which can spread around the battlefield. Without the proper cure in their hand, they can die as well.

Eyes of Future Conquest (Shōrai no Seifuku Me): Causes the fighter to use mind control on the fighter through the manipulation of the blood inside. Excessive use can cause excruciating migraines.

Eyes of Future Tranquility (Shōrai no Shizukesa Me): Unlike the rest, this one comes from the most peaceful clan that encourages peace among the others, the eyes involve in trying to shimmer down the extreme emotions a person is having until they reach a point of staying calm.
