Looks like that particular one isn't on the site, but there's other ones that are very Raygun Gothic. The Scarlet Avenger from Zip Comics leans into the genre a lot though, and gets posted sometimes over at !outofcontextcomics@lemmy.world:
Thanks for the info and links. I'll check out DCM, and I've now subscribed to c/outofcontextcomics@lemmy.world . I already subscribe to a similarly named feed through Pixelfed (but I think it's from Mastodon. I'm still new to the fediverse and not always sure about how it all works).
Yeah, PixelFed and Mastodon work nicely together, they're both basically the same, just with a different UI focus. They can follow Lemmy posts easily, but Lemmy can't follow them easily because Lemmy is built around following communities instead of people.
