Coward

The "Coward" (real name not known) is a boy in Bart's class at Springfield Elementary School. When Bart declares war on Nelson, Coward joins Bart's army.

When Bart first stands up (by himself) to Nelson, and Lisa hails Bart in the cafeteria as "My brother, the bully-killer!", Coward cheers Bart on, then escapes (along with the rest of the kids) when Nelson comes looking for Bart. He joins Bart's army and takes part in the training, but the Guard Dog exercise (where the troops run along a fence with a barking dog on the other side) gets to his nerves and he chickens out. Bart slaps Coward to make him shape up, but Grampa slaps Bart and rebukes him, because sergeants aren't supposed to slap soldiers. Grampa orders Bart to apologize, Coward accepts, and everything's fine. Coward takes part in the attack on Nelson and his weasels, and Bart's army wins.

When Bart takes a picture of Homer dancing with Princess Kashmir and shows it around school, Coward wants a copy.
