Atomic Robo is a FATE-based RPG with a bit of Buckaroo Banzai inspiration (among others). In the revived Atomic Robo Bundle for $25 you get:

Atomic Robo RPG
Majestic 12 - a different org to base campaigns on

Graphic Novels
- Atomic Robo and Other Strangeness
- The Ghost of Station X
- The Shadow From Beyond Time
- The Savage Sword of Dr. Dinosaur
- The Ring of Fire
- The Temple of Od
- The Spectre of Tomorrow
- The Flying She-Devils in Raid on Marauder Island
- The Nicodemus Job

Rules-less Background Material
- Tesladyne Field Guide
- FM-Ultra Field Manual
- Dr. Dinosaur's Time Travel Guide

The two RPG items are all that's been published so this is not so much an RPG line as an RPG with a fiction line. Rather uninteresting since I already have Atomic Robo RPG so only Majestic 12 is of interest to me.

2023-08-31 Addendum: Oh. The comics came first and the RPG is an adaptation. In which case the bundle seems more reasonable to me. (Gaming fiction usually not that great. It takes good fiction for people to make adaptations.)
