Human-looking silhouette

The Human-looking Silhouette is a figure resembling Reg first described in one of Lyza's notes.

Later, after Reg overcharges with electricity from Ido front and loses control, he describes being possessed by a number of people. Two figures come to Reg's mind: Lyza and the unidentified figure.

Appearance
The Human-looking silhouette resembles Reg in it's humanoid shape while also wearing a cape and a horned-helmet with a central display, however, they differ from Reg in many features.

Unlike Reg, their helmet is symmetrical while it's central display is big and centered. The helmet also shows a huge dent on the right side.

Their cape appears to be decorated with armor-like pads and the ends of the cape appear torn in Lyza's doodles, while the collar seems to be in place where, unlike Reg's, the handle comes right below the collar's cavity. Both arms feature huge claws and their hair appears to be quite long.

Personality
According to the description in Lyza's note, they act reserved and were observant of her up to the moment Lyza calls out to them.

Abilities
Lyza points out that while running away from her, they could jump with such a huge strength that it astonished her making her question whether they were really human.
