During the Super Smash Bros. Ultimate Direct two new Echo characters were announced: Chrom and Dark Samus.
About Echo characters
Echo characters are the first official name for clones: fighters who actually have the same attacks as someone else, but with slightly different statistics, such as speed, jumping height and attack power.
Earlier, Daisy, Lucina and Dark Pit were already announced as Echo characters.
How cool is it that Dark Samus is an addition? Sure Chrom is fun but we just have a little less of a connect with the Fire Emblem cast if we are very honest.
