At this point, Nintendo is well aware of the Waluigi backlash that's been caused by once again relegating the character to an Assist Trophy status in Super Smash Bros. Ultimate. The character has long been overlooked in the eyes of Nintendo fans who think that the antagonistic foil to Luigi deserves a spot amongst the playable all-star lineup in Smash. Only time will tell if this will be the case through DLC, but there's no doubt that Waluigi making the cut as an add-on would generate headlines and profits.
This is somewhat of an awkward followup to the above namedrop, but after it was confirmed that Spring Man was selected as an Assist Trophy it began to look as if ARMS wasn't going to receive any representation through a playable character in Super Smash Bros. Ultimate. While others are now clamoring for Ribbon Girl, the loveable Helix may actually stand the best shot at righting this oversight and getting ARMS proper representation in Super Smash Bros.. That's not a knock against the the other fighters from that title, but Helix could provide something much more unique than just extendable arms thanks to its see-through green aesthetic, wobbly movements, and boulder-sized fists.
3. Crash Bandicoot
It's odd to seriously be writing about wanting to see Crash Bandicoot appear as a playable character in Super Smash Bros., but if there was ever a time for the character to make the jump into the fray then now is it. The numbers back this dream combatant up too, as Crash Bandicoot N-Sane Trilogy was the fastest-selling Switch game of 2018 prior to the release of Pokemon Let's Go and Super Smash Bros. Ultimate.
Perhaps the most telling sign is that Crash Team Racing Nitro-Fueled will arrive day-and-date on Switch with other platforms next year, so there's actually a reason that Activision and Nintendo would want to promote the character.
2. Ryu Habusa
Hailing from the notoriously challenging Ninja Gaiden series, it's actually shocking that Ryu Habusa hasn't made his debut in Super Smash Bros. yet. Much like Castlevania, the franchise was integral to the success of the Nintendo Entertainment System, and that legacy helped secure Simon and Richter Belmont's appearance in the latest fighting game. Since Tecmo-Koei and Nintendo have been working together on crossovers with some of the latter's biggest properties (Zelda, Fire Emblem, and even Pokemon) in recent years, fans may be sleeping on this ninja's inevitable addition.
1. Paper Mario
Before we get called out for including three Super Mario characters on this list, it should be noted that two are highly requested newcomers and one is just criminally absent from Super Smash Bros. – the latter is Paper Mario. Sure, there are already two versions of Mario on the roster already, but there are also three versions of Link. At least Paper Mario would play much differently from the non-2D variants of the icon, as he'd have to be equipped with all of his companions and attacks from the RPG titles. This character is long overdue and it's time for him to finally take his spot in Super Smash Bros. Ultimate.
