In the comic books, Colonel Stars and Stripes is actually two characters, Colonel Stars and Lieutenant Stripes. And Sophia? Let's just say, if you're an animal lover, and you adore the above photo simply because of the masked German Shepard...Maybe this movie is not for you.
Here is an official description of the characters from the book, which have been combined into Jim Carrey's Colonel Stars and Stripes. Careful, though this is from the comic book, it does contain some hard core spoilers for the movie.
When Colonel Stars and Lieutenant Stripes both formed Justice Forever, they invited several other superheroes to join. They recruited Remembering Tommy, Night Bitch, Insect Man, and Battle Guy. Soon after, Kick-Ass joined the group, and, after which, the team led an attack on an apartment which had been rumored to be a front for prostitution. Sal had his men attack the lowlifes that infested the apartment, and had his guard dog, Sophia, disable the head of the prostitution plot by signaling the animal to bite down on the man's testicles. After the rescuing the prostitutes, Sal had promised the man that if he had heard any other rumors about the apartment, he would crush him.
Tragically, Sal ended up becoming the first victim of Red Mist and his new gang of super-villains. After killing his dog and trashing his hideout, they left his defiled body to be discovered by the police. His murder almost swayed Hit-Girl to come out of retirement. It is actually implied by Kick-Ass that he may have been in poor health before Red Mist attacked him."
Kick-Ass 2 was released August 16th, 2013 and stars Aaron Taylor-Johnson, Chloe Moretz, Morris Chestnut, Claudia Lee, Amy Anzel, Clark Duke, Augustus Prew, Mary Kitchen. The film is directed by Jeff Wadlow.
