Who broke and who fixed the wings of the postcreated Extreme?
Wing destroyer was the one named Regret.
To be fair, Extreme had swooped over Regret's head a few times too much, just to annoy already pissed off flightless fella, so Regret's counterattack was understandable. Structurally they're like a light-weight flying deer vs. a hyena with wrestling competence, so once caught, Extreme needed to wriggle quite a bit to escape. Regret itself has wings, but they're always been useless, with membrane brittle like paper and torn to bits.
Extreme's wings were fixed (...or, "fixed", but it worked nevertheless) later by a blacksmith, who knew that his proficiency might come with some occasional Special Customers that you serve as good as you can and then try forget everything later.
