Phillip "Flip" Angelopoulos is a former baseball player and the best friend of Hank "Herakles" Grant. He's athletic and studious, but at bit naive. He can communicate directly with the Olympians on the other side of the perception barrier and can allow others to see them by being in physical contact with those people when he communicates with or visits them. Flip's relatively straightlaced nature keeps Herakles from going too far into self-indulgence or too far off track of Herakles' missions.
