The Highbreed Leader is the leader of all of the Highbreeds and controls the DNAliens to do his work. He first appeared in "Ben 10 Returns (1)", the first Ben 10: Alien Force episode. He knows that Max Tennyson knows about the Highbreeds and DNAliens and wants to get rid of him. The Highbreed Leader (voiced by Richard McGonagle) also has multiple wings with orange membranes, scythe-like protrusions on his abdomen, is fairly large and tall, and has purple-and-red markings on his abdomen. He has not battled Ben yet, but talks to DNAliens in what could be their secret hideout. The Highbreed Leader has made a few appearances in Ben 10 Alien: Force on screen.
