No.
You can't unlock Godzilla 80's because Godzilla 80's wasn't added in the game before.
There are cheat codes for Godzilla Unleashed. That is probably the easiest way to do it. Also, you can beat story mode as Godzilla to unlock all monsters. The cheat code is to unlock 90,000 store points. Once you raise enough money to buy all the monsters, buy them. They will be available in both story and brawl modes. The cheat is go to the main menu, (story,brawl etc.),and press x + up. It might take a few times, then input the code, 031406. Keep doing this continuously to raise money, then buy them.
In my opinion, Super Smash Bros Brawl (its my favoritevideo game), but don't ever be asking any opinional sh** on this website again (its getting annoying having to answer all this sh**) !! >_

There hasn't been an announcement of a new game as the slogan for brawl was "A Brawl to end them all!" so it may have been the last one.

Godzilla and Baragon fought in Godzilla, Mothra, King Ghidorah: Giant Monsters All-Out Attack, with Godzilla winning quite easily.
the Godzilla Series is about a radioactive lizard that terrorizes Tokyo all the time. Every movie has a different cast and different plots. The origin of Godzilla is even changed dramacitcally at times (at once he was a mutated iguana and another time he was a dinosaur called "godzillasaurus"). One of the only things that remains the same in the series is that there is a giant monster named Godzilla that attacks Japan.
