SAVE A HOWLER (1968)

The version of the super-villain Klaw (Ulysses Klaw) who featured in the Marvel Cinematic Universe (Earth-199999) appeared to have a bit of a name change, appearing as Ulysses Klaue. This apparent adjustment actually relates back to the character's mainstream Marvel Universe appearances. Not long after Klaw's first appearance, a Nazi character with a similar-sounding name (and missing hand) appeared in Marvel's World War II-centric Sgt Fury and his Howling Commandos #39. Colonel Fritz Klaue is later revealed to be Ulysses Klaw's father, who legally changed his name to Fritz Klaw after the war (see the 'Fallout' section below).

In the story SAVE A HOWLER, Colonel Klaue upgrades his metal hand for one with bionic elements. Giving the middle finger is pretty deadly when Klaue gives it to the Howling Commandos. Though his connection to Klaw wasn't established for some time, yet, he still made life difficult for Nick Fury on more than one occasion before the war was over.

In an earlier story, Izzy Cohen of the Howling Commandos was captured by Japanese soldiers. Now, Captain Savage has learned that Izzy is alive and prepares to send the Leatherneck Raiders on a rescue mission...

Thanks to Thomas Trombley for pointing this one out to me!

Even Klaue's upgraded his metal fist and its array of in-built weapons can't beat Dugan, but he finds himself surrounded by armed troops.
