The free to play online MMO Marvel Super Hero Squad Online is constantly being updated with new heroes and missions, and the latest to join the team's roster is the ever popular Deadpool! Though his popularity has surged drastically in recent years, he's always been a fan favorite. This intrigues me once again, as it shows that the team is trying their hardest to appeal to fans of all ages by including characters like Deadpool or as we previously saw, "Gladiator Hulk" from World War Hulk.
