What other third party franchises should be added to Super Smash Bros. Ultimate?

[ApolloVI]

So far, the following third party franchises are confirmed for the game with playable characters:

• Metal Gear (Konami)
• Sonic the Hedgehog (Sega)
• Mega Man (Capcom)
• Pac-Man (Bandai Namco)
• Street Fighter (Capcom)
• Final Fantasy (Square Enix)
• Bayonetta (Sega/PlatinumGames)
• Castlevania (Konami)

Who else deserves a spot on the roster? Personally, I would say a Dragon Quest representative would be fitting given the franchise's deep roots with Nintendo. Erdrick would be a nice choice. 

In addition to that, I think Rayman would make a neat addition. He was a trophy in Smash 4, and Ubisoft has grown tight with Nintendo in recent years (see: Mario + Rabbids, Fox's appearance in Starlink). What do you think?

Undertale or Silent Hill perhaps?

For the love of god made Shante and shovel knight official characters! A crime for them not to be.
