Super Smash Bros. 4
Super Smash Bros. Ultimate
Chrom appears in Super Smash Bros. Ultimate as Roy's Echo Fighter. Chrom's inclusion was primarily facilitated by popular demand both within and outside of the Super Smash Bros. Fighter Ballot. In a Famitsu interview shortly following the August 2018 Smash Bros. Direct, Masahiro Sakurai revealed that Chrom and fellow Echo Fighter Dark Samus were highly requested characters but in different regions of the world; most of the support for Chrom came from Japan while Dark Samus's came from overseas, being North America and Europe.
- Chrom is the second character in the series from making cameos in a fighter's Final Smash, then playable in the next installment. Palutena is the first character to do this.
- In the Mysterious Dimension sub-area in Ultimate, there is a quiz asking which spirit is Chrom's younger sister.
- Chrom so far is the only fighter in the Super Smash Bros. series to have their victory theme be changed via game updates, as in Ultimate he previously had the standard Fire Emblem victory theme before it was changed to the Awakening victory theme in version 3.0.0.
