For the most part he exists solely in Vayne's mind, however he materializes in Heart's Prison to grant Vayne's wish to be alone. His sole reason for existing is to grant Vayne control over his power to grant wishes, and so his sole goal is granting Vayne's every wish, even his darkest desires. He also is a warped version of Vayne's personality, despite this he seems to be a playful and a bit sarcastic in his appearances. It is unknown if he has any attachments to people, since he is technically Vayne as well.
Other Vayne is the one to have convinced Vayne to use his powers in times of need. Such a time would be when Isolde killed one of his friends or when the Huffin tree was burnt down. In the final chapters he is revealed to be the personification of Vayne's powers and is the one to give Vayne back his memories of Theofratus; thus causing him to feel guilty about his death.
He is found in the center of Heart's Prison, the Illusionary Path, and is the final boss for the good endings In the bad ending he and Vayne are the final boss and both are not known to have lived or disappeared in the collapse. In the good endings, he is shown to sit down in the center as the workshop left the collapsing realm; it is unknown if he still exists or not.
Boss BattleEditOther Vayne takes the form of Crazed Eye in the true final battle in the good endings and has a similar arsenal of attacks as the previous fight with Vayne, though he summons familiars as well. He takes this form when Vayne decides he doesn't want his power anymore and so he no longer has a harness.

- He is referred to as Vain by most fans.
- Perhaps his character is a reference to Vayne's name's original spelling of Vain, which means Vanity. And he seems to only care about Vayne to an extent.
- Interestingly enough, he resigned himself to his fate when Heart's Prison was disappearing in the good endings, as seen by him sitting down while it collapsed on itself.
- While being the final boss, he never seemed truly malicious. He has said multiple times he wasn't the one to wish for the whole Heart's Prison incident to happen and that he's just the personification of Vayne's power.
