It’s the only one that wasn’t in the trailer. So we don’t have a good full look at it.
We don’t have much on the White and Black riders either.
Although White rider appears to have two Shekinah. One held one stowed. In addition to the beam spot guns, and a beam saber with a hand guard (as a rider should have).
Black Rider on the other hand seems to be a stealth raid with large possibly jamming devices on its back. Keener eyed folks see a Gouf custom sword on its left hip (possibly cold like the Nachts, to avoid creating thermal readings). It also has an armor pile on the left arm, which in the game with either just increase its tackle damage, or will be a fast attack that inflicts heavy stagger (it’s gonna be a better Pixy in every way it seems).
