Hanna-Barbera produced this Marvel property. Compared to its cousin Spider-Man, it doesn't have the iconic song although it does have the jazzy theme. It's not quite as action-packed fun. It's better than the 1978 series which ran without the Human Torch. This lasted for a season. Ownership probably separated the two shows. It also is more bent towards sci-fi. This is a classic cartoon at the dawn of a new era.
