The wildest thing about Ben 10 is that it took until 2005 for someone to have the idea "what if a kid could turn into a bunch of aliens" like this isn't obviously the coolest and most marketable premise for anything ever. Each design is a new toy. A new powerset. Come on.
But to prove that it wasn't a fluke, they continued to have the best ideas for every aspect of it. How does he transform? A cool watch you can also sell as a toy. That watch's name? Omnitrix. Say it. It's so satisfying. How many aliens? Ten. Nice round number. The kid's name? Ben. The show's name? Ben Ten. His full name is Benjamin Tennyson, a normal, plausible name, but he also turns into 10 aliens.
Bigger brands dream about this synergy. Better writers would kill for this coherence. So holistic. So intuitive. The identity alone!!! The retro alien sound motif? Chilling. The green? Any other color would be wrong. The kirby krackle pattern? It seems so obvious in retrospect. The roadtrip format? Genius. Lesser writers would've done the spider-man high school thing. His arch nemesis being Cthulhu darth vader? Inspired, iconic, intimidating!
The execution has its highs and lows, but the idea??? Game changing. So self-evident that it seems inevitable. If Ben 10 didn't exist, it would be necessary to invent him.
And in every possible iteration he would have a rival named Kevin Eleven.
