Echo Fighters for characters first appearing in the original Super Smash Bros.
2. Funky Kong
Original Fighter: Donkey Kong
Odds: Medium
Funky Kong is already sort of a ripoff of Donkey Kong. He has the same body type but throws on some shades and a bandanna. Man, this guy is the definition of cool!
Funky could easily be a DK Echo fighter. Though if Sakurai went the extra half-mile he could maybe incorporate Funky's surfboard into the ground slapping attack!
3. Dark Link
Original Fighter: Link
Odds: Very Low
Dark Link is seen in many Zelda titles, so it's not surprising he made this list. However, he's practically bound not to happen as Link has a Dark Link costume.
5. Boshi
Original Fighter: Yoshi
Odds: Low
Another version of Yoshi is the famous character named Boshi from Super Mario RPG: Legend of the Seven Stars. Like Funky Kong, this Yoshi is '90s cool boasting shades and a spiked collar.
While implementing Boshi would probably be easy, I doubt it will happen. While Square Enix, the company who probably owns the rights to Boshi, has characters in Smash Bros. Ultimate, I doubt this is a character they'd bother pushing. How many people care enough about Boshi anyway?
6. Shadow Kirby
Original Fighter: Kirby
Odds: Low
Shadow Kirby is a version of Kirby from the Mirror World found in Kirby & The Amazing Mirror. Shadow Kirby has also appeared in other Kirby games as well.
There isn't much of a noticeable difference between Kirby and Shadow Kirby, so this character may be better handled as a special costume for Kirby. Besides, I doubt the developers want to test each version of Kirby's Copy Abilities with two fighters.
7. James McCloud
Original Fighter: Fox
Odds: Low
Fox's father looks just like him, but with aviator shades. Yes, this is another Echo Fighter that may just make a better costume.
That said, it would be cool if James appeared as an apparition like how Force Ghost Obi-Wan is seen in the Star Wars movies.
10. Ninten
Original Fighter: Ness
Odds: Medium
Ness is the star of Earthbound (Mother 2). Lucas is the star of Mother 3. That's why it would make sense to see Ninten, the Star of Earthbound Beginnings (Mother), appear as an Echo Fighter for Ness.
It may have taken a long time, but Earthbound Beginnings did finally make its way west on the Wii Virtual Console. It could happen.
11. Blood Falcon
Original Fighter: Captain Falcon
Odds: Very Low
Blood Falcon is an evil clone of Captain Falcon. That's basically the perfect plot to create an Echo Fighter. Sadly, Captain Falcon has been spotted in Smash Ultimate wearing Blood Falcon's Hell Hawk jacket as an alternate costume, so it's probably not happening.
