Frédipo da Silva, (or Grande Mestre, literally Great Master; as he proclaims himself) is the main antagonist of the Monica's Gang episode, O Sumiço de Todas as Mães. He is a spoiled brat who manipulates a robot army to kidnap all mothers in the world for selfish reasons, because he lost his mother.
Since his birth Frédipo has always been considered an ugly kid. By having only his mother to defend him from the bullies he grew up as a spoiled child. When he was three years he lost his mother in a supermarket. From that day all bullies began to tease Frédipo calling him as dwarf and ugly.
Many years later he built his own robot army to spoil yourself, and as if that were not enough he ordered to their robots kidnap the mothers of all the children of the world in a selfish act. Therefore Monica and Maggy joined forces to disguise as mothers and be brought to the Frédipo's hideout.
