Uncanny Avengers' return in Fall of X was pretty surprising. While bringing back the Avengers Unity Squad in the Krakoa Era makes sense, relaunching Uncanny Avengers this late in the proceedings feels a bit like a missed opportunity. However, the book has been doing pretty well, as writer Gerry Duggan and artist Javier Garron deliver an action-packed ride. The premise is pretty interesting. Orchis has recruited a secret villain to steal the Captain Krakoa costume and impersonate the mutant nation's great hero. As "Captain Krakoa," this imposter has brought together a group of mutants to act as terrorists, further turning the public against mutants.
