Brando

Brando appears in The Greatest Robot in the World. He is a big burly robot that has the ability to spin at high velocity and turn into a deadly sphere that grinds up anything it comes in contact with. Bruton fights against him and Brando is defeated, but Bruton is severely damaged afterwards, making Brando one of the few robots that were strong enough to even damage Bruton. in the manga and the 1960s anime, Brando fights Bruton to avenge the death of his friend, Montblanc. in the 1980s anime, it is Monar's death he is avenging, and Bruton's master clearly tells him that if he destroys either Brando or Monar, the one left will avenge the other.
