Caliborn

Not to be confused with his adult version, Lord EnglishCaliborn is a cherub with cherry red blood from a dead session of the game who shares a body with Calliope. He was confirmed to be the young Lord English.

Biography
Caliborn is the so-called brother of Calliope, with whom he shares body with. He's extremely rude and ornery, the exact opposite of Calliope.

It is revealed that he's a Derse dreamer, while his sister is a Prospit dreamer. He keeps calling himself a "Derse guy" when explaining to Dirk why he couldn't kill his sister himself (hence the fact he had to hide Agents to do his dirty work)

Later on it is revealed that Caliborn is the Lord of time, this confirming 2 this:

1. He is one of the essential players of his session, the other being his sister as the Muse of Space.

2. Due to his Clas-spect, it is revealed and confirmed that he is the young Lord English.

Personality
Caliborn's typing is the exact opposite of Calliope's, capitalizing every letter except U's. However, he later changes his color, claiming the trophy of killing his own sister.

He is possibly the most rude character in the comic, second, of course, being Karkat. He also seems to be the "most alien" of all of the characters in the comic (let's not forget there are, alone, non parallel universe, over 100). He has a great obsession with playing games, his love for them surpassing the human ability of comprehension for love, as stated by Calliope.

Abilities
Aside from his time powers which he surely hasn't used yet, he is a "very skilled" artist in development. He is the one and only creator of Homostuck, a mockery of the actual comic. He also seems to be able to break the 4th wall. He feels no remorse what so ever to killing his sister, if that can be called an ability. And he surely doesn't give a damn about his pain.
