In this feature we spotlight the various characters, phrases, objects or events that eventually became notable parts of comic lore. Not major stuff like "the first appearance of Superman," but rather, "the first time someone said, 'Avengers Assemble!'" or "the first appearance of Batman's giant penny" or "the first appearance of Alfred Pennyworth" or "the first time Spider-Man's face was shown half-Spidey/half-Peter." Stuff like that. Here is an archive of all the When We First Met features so far! Check 'em out!

This is the second in a three-part look at the debuts of notable SHIELD agents. Click here for the first part, which spotlighted SHIELD directors. Today we look at notable members from the first twenty years of SHIELD's existence.

Jimmy Woo first showed up in the short-lived 1950s Marvel series, The Yellow Claw (he was present from the first issue as the FBI agent assigned to take down the Yellow Claw).



Jim Steranko later brought him back in Strange Tales #160 in a new Yellow Claw tale...



At the end of it, Woo believes that Fury killed his one true love (the Yellow Claw's niece). He vows vengeance. Fury explains to him that the woman killed was not really a woman, but an automaton. So Woo joins SHIELD in Nick Fury, Agent of SHIELD #2...



Jasper Sitwell was the first major addition to SHIELD in the pages of Strange Tales, joining the team in Strange Tales #144...







Steranko added two extremely notable characters when he took over the book, beginning with La Contessa Valentina Allegra de la Fontaine in Strange Tales #159...



and then Clay Quartermain in Strange Tales #163...



(Later in the issue, Nick realizes that Clay can hold his own)





Along with Nick Fury and Dum Dum Dugan (and Sharon Carter, to a certain extent) these would be the backbone of SHIELD for the next forty-plus years.

Next installment will be for more recent additions to the world of SHIELD!
