OK hear me out-

1. Xolum from a universe where Vebs dead meets the original Veb, whose original Xolum died.

2. Xolum's body remained so they can revive him, becauss sciences, Xolum's head get replaced by another object and he lives another day, but he has to get used to his new head.

3. Veb goes on a journey of self discovery and self worth.

4. Xolum and Veb goes on a life threatening adventure to save the quantum realm.

5. Instead of Xolum dying, Veb died, so he is absolutely enranged and probably need therapy, so he faces of Kang and help defeat him, instead of dying in the hands of Kang. Basically I book full of angst and a book about Xolum coping through depression and growing anger issues.

Pls use them.
