In Mark Twain's "A Cub Pilot", Mr. Bixby, who is the main captain of the steamboat, plays the role of some sort of mentor to young Mark Twain, someone to look up to, because he has has always wanted to become a steamboat pilot. His main teacher, Mr. Brown, is rude and violent to him, while Mr. Bixby is not. He sort of represents wisdom and young Twain's perseverance to become a pilot in chief.
Answer:
A character that could fit into the story of the Iliad would be the god Harthos, protector of Troy.
It would be an antagonistic god to Zeus, protector of the Hellenic peoples, since Harthos would protect the Turkic peoples beyond the Aegean Sea.
Being twin brother of Zeus, both would have divided their territories establishing as limit the Aegean Sea. Both had the same powers because they were identical twin brothers.
When the Greeks invaded Troy, Harthos supported his people to repel the attacks. He collaborated with the deaths of Patroclus, Ajax, and other Greek warriors. Zeus came to help Achilles to kill Hector.
The confrontation happened to be direct between both gods. When the Greeks built the wooden horse, Zeus and Harthos fought to settle their differences. Zeus ended up winning, sending Harthos into exile, so he could not protect his people, who ended up being cheated and defeated by the Greeks.
