In late 1977, the Incredible Hulk live-action TV series started airing and it was a huge hit. Even though my kids can't fathom how the show had such a huge following (they can't believe how small and human-looking Hulk is), it was one of those "must see" shows for many kids in the 1970s.
Mego, having already produced an 8" Hulk figure, released their 12" Hulk figure in 1978... right on the heels of the popular TV show. Sure, Mego's Hulk looks nothing like Lou Ferrigno's Hulk, but the synergy between the toys and tv show was there, all the same.
Mego's 12" Hulk features an excellent comic-book-accurate face sculpt. He also features quite a bit of articulation. To be complete, he should have both his purple pants and white (factory torn) shirt.
The Hulk is one of the "high marks" in Mego's 12" Superhero line of figures. Although, I don't like him when he's angry.
