Zenra (Zero's Nightmare)

Xadiel was born from X's nightmares of failing other people and causing their deaths. He's more subdued than X and not as emotion but he's sharper and more dominant.

He was very fond of people that he considered close to him and can be yandere-ish - he doesn't put up the dere front but he's very possessive.

Xadiel was born first, but realized there was no way Zero wouldn't also produce a nightmare, so he hid and waited for it to happen and then snatched him away, where he then began a campaign of terror across the wilds.

Xadiel is interested in learning basically everything. He's immensely intelligent.

Zenra is also intelligent but happy to let Xadiel take the lead and allows him to essentially hold his leash. As a berserker type there's times when even Xadiel can't hold him back, but for the most part, he tries to obey him.

The two of them are ridiculously cute together. Also they flirt and stuff.

When let off the leash, Zenra tends to leave a bloody trail and relishes in it.

Xadiel is apathetic about everyone he hasn't bonded with yet.
