I’'m the spirit of vengeance (Dazed)

[XeneizeJCDC]

Since superpowers are referred not to be active while a character is dazed, and CGR remains dazed until the end of the Clean Up, I assume that he can’t remove the dazed token, and doesn’t throw dice to gain power, Am I correct? 

[Thoras]

This is correct, yes.

A character removes their dazed token and flips to injured in step 4 of the Cleanup Phase.

Since this superpower occurs in step 2 of the cleanup phase, you wouldn't perform any of it as the character doesn't have the superpower at that time.
