Ben 10
Ben 10 turned a simple wish-fulfillment premise, a kid finds a watch that lets him become aliens, into one of Cartoon Network's most durable franchises. The 2005 original and its successors, Alien Force, Ultimate Alien, and Omniverse, grew up alongside their audience, shifting from monster-of-the-week adventure toward serialized stakes and an ever-expanding roster of transformations.
The brand sprawls across media. Animated movies and a 2016 reboot sit beside tie-in games like Protector of Earth and Cosmic Destruction, plus the live-action TV films Race Against Time and Alien Swarm that tried the concept in flesh and blood. It is uneven by design, constantly relaunching itself, but the core idea has proven strong enough to survive every reinvention.
The Ben 10 franchise spans 5 series, 2 games, 8 films in the CrossBinge catalog.
