In Brazil, the Odyssey² was known as the Odyssey. The "2" was unnecessary because Magnavox's Pong-like Odyssey consoles were never released in Brazil.
Philips began to market the Odyssey in Brazil at about the same time as the console's popularity was dying out in the United States. In Brazil, however, the machine was quite popular and sold well, leading Philips to release practically every game in their European library for sale in Brazil. Philips even published some games in Brazil they didn't release anywhere else, and licensed other companies' titles for Brazilian publication.
In Brazil, it was Philips who published titles from Imagic and Parker Brothers, assigning them new part numbers and giving them new cartridge labels. However, the boxes for these games appear practically identical to their non-Brazilian counterparts, except they are printed in Portuguese. I would guess that this was a cost-saving move on Philips's part.
The Voice module never made it to Brazil, nor did Type & Tell, Sid the Spellbinder, or Nimble Numbers Ned -- the games that require The Voice. A company called Dynacom announced plans to release the Voice and these games, but never did so.A company called MSP/Gadgets announced a game called A Turma da Mônica, to be based on famous Brazilian comic strip characters created by Mauricio de Sousa (MSP stands for Mauricio de Sousa Produções). It was never released, and no prototype of this game has been found.
The Brazilian "exclusives" are Comando Noturno! and Clay Pigeon!. Prototypes of both games have been found in Europe, but the games were only officially released in Brazil. One copy of a multigame cartridge called Missão Impossível/Viagem Programada has also been discovered. It was released by a company based in São Paulo, and doesn't correspond to any games released outside of Brazil.
