I don't know what the "7" is in your question, but the maker of Super Smash Brothers is Masahiro Sakurai, and he's 37 years old.
To unlock Pichu, complete Event 37 called Legendary Pokemon.
In order to unlock Pichu ( Clone of Pikachu ), you must beat event match #37, where you must fight him. An alternative is to Clear Classic Mode with Mewtwo. You may also fight 200 vs. matches.
You complete the Mewtwo event match number 37 and Pichu will appear. You fight Pichu and win. That is how you get Pichu.
you need to unlock a few characters involving Jigglypuff, Falco, and Dr. Mario.
There are 35 character options, but as Zelda can transform to Sheik and Samus can become Zero Suit Samus, there would be 37 characters in total. Ivysaur, Charizard and Squirtle are not counted as three different characters, as their character is Pokemon Trainer.
37, but 35 if you don't include Zero Suit Samus and Sheik, who are the same characters but in a different form. Squirtle, Charizard, and Ivysaur count as one character.
