Based on the line of toys and TV series, Marvel Super Hero Squad is being brought to Wii by THQ in the near future. It appears to be geared towards youngsters and the LEGO Star Wars crowd, with simplistic combat and an emphasis on co-operative play. You'll find around twenty characters, both heroes and villains, and there are dinosaurs hanging around in there, too, which is always nice.
Some of the first screens, with more to be found in the media album:
