- "Well, may we get what we want!"
"May we get what we need."
"But may we never get what we deserve."

They participated in World War I on the side of the Allied Powers, assisted from London by Etta Candy, Steve's secretary. While their leader Steve perished, the team ultimately succeeded in their mission, which resulted in the end of the war.
Promising to take Diana Prince to the Western Front, Steve Trevor set about putting together a team to assist them. The team's purpose was to stop the plans of Dr. Poison, General Ludendorff, and Ares, and they succeeded and that resulted in the end of the war.
After the end of the war, the British found a Mother Box buried in Belgium soil and asked Etta and the Wonder Men to recover it and deliver it to the Americans. Afterwards, the various members of the Wonder Men died one by one, leaving only Diana as the last living member for a time. In 1984, Steve Trevor came back to life for a short period, assisting Diana in her mission to stop Max Lord's destructive search for power. However, Steve soon ceased to live when Diana renounced her wish.
