Constellation:

Character:

The hero of 100 years ago and the one who 'defeated' Glen Baskerville. He is revealed to have some sort of connection with Alice's memories and Raven's past. Jack looks uncannily like a grown-up Oz with a long plait. His personality is also quite similar; he does things at his own pace and is loud and cheerful. Oz and Gilbert meet him when they are taken to the Cheshire Cat's dimension.
