Cal is the 18 year old son of Lisa and Sean Morro. Sean is deceased and Lisa is currently the Ichthyologist about the Endeavour. He is cocky, outspoken and doesn't worry about hurting anyone's feelings. He is quick to begin fights, yet takes his dream of being in Starfleet Security seriously. While Cal is not a good listener, he is good at seeing what's going on and will call it to a person's attention.
