These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Accidental Innuendo: On the part of the series' creator; The hero's codename is Shaft? Come on.
Badrock is easily the most popular member of the team - and the only one to be in every single version of it.
In-universe, Troll was established as one to set up a bit of conflict between him and the equally in-universe popular Badrock. Out of universe, not so much.
Fridge Brilliance: It's possible that Liefeld didn't just choose the name "Youngblood" because it sounded cool. After all, he had gained a lot of popularity with his X-Force work, and since "Youngblood" begins with a Y and "X-Force" begins with an X, anyone looking for his X-Force issues would be likely to see his new comic right beside them on the shelves of the comic book stores. This might also be the reason why Todd McFarlane, who'd previously worked on Spider-Man, named his new hero "Spawn."
Hilarious in Hindsight: Youngblood began as Liefeld's idea for Roy Harper leading a team of Titans working for the government. Two years after the first Youngblood issue, Roy Harper was leading the Titans for the government.
Narm: "Badrock" isn't as cool a name if you're from Sweden, since it's Swedish for "bathrobe."
It's not much better in English as it brings to mind The Flintstones more than anything.
