Marvel has released five new covers as part of its "Marvel '92" variant initiative, which celebrates the characters, storylines and artists of Marvel Comics in the '90s this December -- not limited to just 1992, but taking its name from the publisher's current "X-Men '92" series.

In the latest crop, Marvel flashes back to the Clone Saga with Mark Bagley's "Web Warriors" #2 cover (complete with Kaine, the Scarlet Spider and clone Gwen Stacy); "Heroes Reborn" with Whilce Portacio returning to that world's Iron Man in an "Uncanny Inhumans" #3 variant; "Force Works" with Portacio's sadly Century-less "Uncanny Avengers" #3 variant; Julia Carpenter's time as Spider-Woman in Bagley's "Silk" #2 variant; and Carol Danvers' years as a space-faring Ms. Marvel in a "Ms. Marvel" #2 variant by J. Scott Campbell.

Here are all five of those variants, plus 16 that have been previously released:
