Franz Gruber was Baron Zemo's pilot and right-hand man. He aided Zemo when he first assembled his Masters of Evil. After Zemo died, Gruber took his place and launched an invasion of Wakanda, pretending to be Zemo. He was defeated and unmasked by Captain America and the Black Panther. When the soldiers working for him realized he was an imposter, they shot and killed him. The soldiers then surrendered to Wakandan forces.
