Ridley Revolutionさんのイラストまとめ

43. Bomberman
Franchise: Bomberman series
Debut: Bomberman (1983)

As you would've guessed, he uses bombs. Can also use Power Gear, and he can call forth allies, like Louies and Charaboms. Maybe borrow abilities from other Bomberman characters? It worked for Ness and Lucas.

40. Shovel Knight
Franchise: Shovel Knight series
Debut: Shovel Knight

Steel thy shovel! The king of Indies has arrived. Shovel Knight uses his trusty Shovel Blade as his weapon. There's also potential of knight vs dragon (a common trope) in Smash, Shovel Knight vs Ridley.

38. Crash Bandicoot
Franchise: Crash Bandicoot
Debut: Crash Bandicoot (PlayStation, 1996)

Crash was originally a rival to Mario and Sonic, but has made his way onto Nintendo platforms. He can use his signature spin attack, but he has other abilities up his sleeves.

35. Shantae
Franchise: Shantae series
Debut: Shantae (Game Boy Color, 2002)

This half-genie hero can transform into different forms. She also used Risky Boots' items in Pirate's Curse. She was once described as "the undisputed queen of indie characters". Shantae is Ret-2-Go!

32. Mii Mage
Franchise: Super Smash Bros. series / Mii series
Debut: Miitopia (Nintendo 3DS, 2016)

Expanding the Mii Fighters beyond the three currently in the game has been in speculation for some time. Mii Mage just makes sense.

31. Mike Jones
Franchise: (Retro characters)
Debut: StarTropics (NES, 1990)

A western retro rep. The issue here is that his game wasn't released in Japan initially. He also uses a baseball bat and yo-yo, which would make him too similar to Ness. Though they can make him work.

29. Max Brass
Franchise: ARMS series
Debut: ARMS (Nintendo Switch, 2017)

ARMS veteran, champion, and the head of the ARMS League. The big guy would easily be a super heavyweight character. He's also important to the ARMS lore, or so I've read.

27. Gruntilda
Franchise: Banjo-Kazooie series
Debut: Banjo-Kazooie (N64, 1998)

The main villain of the series. This wicked witch created a machine to transfer an entity's beauty to another, which would be Tooty (Banjo's sister). She uses magic and uses a broomstick to fly.

26. Slime
Franchise: Dragon Quest series
Debut: Dragon Quest (NES, 1986)

I was kinda stumped on this one. Slime are the mascots of the series, and a recurring enemy. I don't know how they'd work. I best leave that to Dragon Quest fans.

25. Jack Frost
Franchise: Shin Megami Tensei: Persona series
Debut: Megami Tensei II (Famicom, 1990)

I'm unfamiliar with this series. Jack Frost can be considered the mascot of Atlus and the Megami Tensei franchise as a whole. Looks cute, but I doubt he's friendly...
