Captain Cosmos is the first in command in the The Adventures of Captain Cosmos. He travels to space with his trusty sidekick, Jangles the Moon Monkey, with his second in command, later weapons specialist, Stella Skyfire. In 2071, he appeared with the Silver Shroud in a Thanksgiving crossover episode entitled The Silver Shroud vs. Captain Cosmos.

And then we all listened to, "The Silver Shroud vs. Captain Cosmos." Even pa was there.You ever listen to the Silver Shroud? That's who we need. No matter how bleak things got he'd save the day."

↑Fallout: New Vegas Official Game Guide Collector's Edition p. 409: "Rocket Viewing Chamber Chris Haversam works here while Jason Bright readies his followers for their final trip into the stars. The hatch down to the Rocket Launch Pad cannot be accessed. You can also speak into the Intercom (which results in amusing conversation if you haven’t entered the Research Lab yet). Finally, check the Unique items on the shelf, if you want to dress up as Captain Cosmos!" (Tour of the Mojave Wasteland)
