Super Smash Bros. Ultimate was announced for Nintendo Switch, on the Nintendo Direct presentation during E3 2018, and the biggest thing to know is that everyone is here. Every single character that has ever been in a Smash Bros. is back again, along with at least two new additions in Ridley and Splatoon's Inkling. For those who are coming back from a previous game, there will be some changes.

Some are mechanical, some are cosmetic, some are minor, and some are major. Here are all the ones we know so far, based on information given to us during the Nintendo Direct and based on our own hands-on experience.
