Unfortunately no, there are no real boy-themed character meals to date. Of course you mention some great meals where Mickey and the gang and Winnie the Pooh and friends are featured, but that is as much for girls as for boys. But as to an Aladdin, Hercules, or Pirate-themed Character meals, no, there are none to date.
What I recommend to parents of little boys that can come a bit closer to their "cup of tea" (with no actual tea involved!) is to try the
Whispering Canyon Cafe,
Mickey's Backyard BBQ, and
'Ohana. These, like the meals you mentioned, are good for both boys and girls. But the fun western theme of the first and second can really let him know that everything is not frills and lace. The third can be fun too, especially for younger boys.
Another thing to consider is the Island of the Caribbean Pirate Adventure cruise. This children's adventure cruise (ages 4-10) lets them be pirates, searching for treasure and having a lot of fun. Lunch is included, but it is for the kids only. No parents allowed! Call 407-939-3463 for more information. It might just fit the bill!
Have a magical vacation!
