Super Smash Bros. Ultimate has one of the most active modding communities in gaming, with thousands of creative modifications available on GameBanana. From quality-of-life UI improvements to entirely new character movesets, these mods transform the Ultimate experience in exciting ways.
The modding scene offers everything from simple visual tweaks to complex gameplay overhauls. Whether you’re looking to add requested characters that never made it into the base game, refresh existing fighters with new movesets, or simply improve the user interface, there’s a mod for that. This list covers the ten best mods currently available for Super Smash Bros. Ultimate in 2025.
Mod Manager Button Over eShop
One of the most practical UI modifications available is the Mod Manager button replacement. This mod replaces the eShop button on the main menu with a dedicated “Mod Manager” option, featuring custom artwork with Waluigi and Dry Bowser in the center circle.
While it seems simple, this mod required extensive work due to how the eShop button’s color links to the online button’s background. The creator had to design a texture that displays on top of the yellow background to achieve the proper visual effect.
This mod is incredibly useful for managing your modification library directly from the game interface. Instead of manually navigating file systems to enable or disable mods, you can toggle them on and off through an in-game menu. This is particularly helpful when testing new mods or troubleshooting conflicts between different modifications.
Important Note: This is a complete menu mod, meaning it can’t coexist with other mods that change menu colors. If you’re using another menu UI mod, you’ll need to manually extract specific files from this mod to integrate it.
The main advantage? Having direct access to mod management without external tools makes the modding experience significantly smoother and more user-friendly.

Ultimate CSS 91+ Layout Fix (170 Slots Update)
The default character select screen in Smash Ultimate has a limited number of slots, which becomes problematic when you start adding multiple character mods. The Ultimate CSS Layout Fix solves this by expanding the roster capacity to 170 slots, with support for even more coming soon.
This mod has gone through significant development. The 170 Slot Update improved character portrait sizes and name text for every icon size, while also adjusting icon dimensions to prevent clipping through the sides of the screen for rosters up to 98 slots.
Technical Achievement: The creator discovered how to scale down CSS icons by manually adjusting icon sizes in the chara_select_btn0_00_window_size animation files, then editing chara_icon_arrangement.prc to increase slots per row. This allows for much smaller icons than previously possible.
Why This Matters: Without this mod, your game will crash once you exceed the default slot limit. This is one of the most common reasons modded games fail to boot. If you’re planning to add multiple character mods, this fix is absolutely essential before you start downloading fighters.
The mod continues to receive updates, with the creator working toward supporting the full 255 slot cap. For anyone building a massive custom roster, this mod is mandatory infrastructure.

Alucard Moveset
The son of Dracula finally joins the battle alongside the Belmont Clan as a fully playable Castlevania representative. Alucard brings his signature sword mastery and dark magic abilities to create a unique and powerful fighter.
Moveset Overview: Alucard excels at mid-range combat with his heirloom sword, which has exceptional reach for controlling space. When opponents close the gap, he can respond with quick melee strikes. His special attacks and smash attacks utilize dark magic for devastating damage output.
Dark Metamorphosis Mechanic: When your health is critical, Alucard’s command grab triggers Dark Metamorphosis mode, allowing you to heal with each successful sword hit. This comeback mechanic adds strategic depth and makes Alucard a genuine threat even when behind.
The moveset captures Alucard’s playstyle from the Castlevania series while adapting it perfectly for Smash’s gameplay. He feels like a natural addition to the roster, with unique mechanics that set him apart from existing sword fighters.
This mod represents the high quality that the Smash Ultimate modding community has achieved. Complete movesets like this require extensive programming, animation work, and balance testing to feel right. Alucard delivers on all fronts.

Waluigi Moveset (Final)
The most requested character in Smash history finally gets his due. Created as a response to the overwhelming community demand for Waluigi’s inclusion, this complete moveset transforms the assist trophy into a fully playable fighter with unique abilities and personality.
The Final version includes extensive polish and bug fixes, with the creator providing detailed installation instructions for different setups. This isn’t just a simple character swap, Waluigi has custom animations, unique move properties, and mechanics that feel true to his personality as gaming’s favorite underdog.
What Makes It Special: Waluigi’s moveset incorporates references from across the Mario franchise, including sports games, party games, and various spin-offs where he’s appeared. His lanky frame and exaggerated movements translate perfectly to Smash’s gameplay, creating a fighter that’s both comedic and competitively viable.
The mod includes voice lines, effects, and all the polish you’d expect from an official fighter. It’s a testament to what dedicated modders can accomplish when they’re passionate about a character.
Community Response: This has been one of the most downloaded character mods, proving that Waluigi’s fanbase isn’t just vocal, they actually wanted to play as him. The “Final” designation indicates this is the complete, definitive version after extensive community feedback and testing.

Funky Kong Moveset
Funky Kong surfs into battle with a completely original moveset that captures his laid-back personality and impressive athletic abilities. This comprehensive mod includes everything needed for a complete fighter experience.
Full Package Included:
- Custom moveset with unique mechanics
- Base skin plus 7 recolor alternatives
- Complete UI integration
- Custom voice lines and sound effects
Funky Kong’s moveset draws inspiration from the Donkey Kong Country series, incorporating surfboard attacks, tropical-themed specials, and his signature chill attitude. He plays differently from the existing DK fighters, offering a fresh take on the Kong family’s representation.
Performance Note: The creator emphasizes that 99% of crashes with this mod come from outdated or missing dependencies. Make sure all required plugins are updated to their latest versions before reporting issues.
The development was supported by extensive community testing and feedback, resulting in a polished fighter that feels professionally designed. Funky Kong has quickly become a fan favorite in the modding community, proving that sometimes the wackier character choices make the best fighters.

Super HYPE Bros. – Moveset Modpack

Dread Samus – Samus Rework (Dread Inspired Moveset)
This comprehensive rework reimagines Samus’s moveset by drawing inspiration from the Metroid games, particularly Metroid Dread. Instead of creating a new character, this mod transforms the existing Samus into something that feels more authentic to her source material.
Major Additions:
- Flash Shift: An entirely new side special that provides quick evasive movement, taken directly from Dread
- Speed Booster: A new core mechanic that builds momentum as you run, culminating in the devastating Shinespark attack
- Morph Ball Overhaul: The down special has been completely revamped with new functionality
- Slide and Melee Counter: Movement and defensive options inspired by Dread’s gameplay
Balance Disclaimer: The creator openly admits this version of Samus is overpowered. Current focus is on implementing cool mechanics from the Metroid games rather than competitive balance. Future updates may tone things down, or lean even harder into the chaos.
This is a partial moveset modification, meaning it changes many of Samus’s moves while keeping some of her original kit intact. It’s not Wi-Fi safe, so only use this in local matches or with friends who also have the mod.
The result is a Samus that feels like she actually plays the way she does in Metroid games, with mobility options and aggressive tools that weren’t present in her vanilla moveset.

Spider-Man
“All right, let’s do this one last time.” Spider-Man swings into Smash Ultimate with a comprehensive mod that includes multiple suit variations and complete character integration.
Included Suit Variations:
- C00: Advanced Suit 2.0 (with Symbiote Suit alt)
- C01: Classic Suit (with Classic Black Suit alt)
- C02: Superior Suit (with Symbiote Suit alt)
- C03: Black Suit (with Anti-Venom Suit alt)
- C04: Advanced Suit 2.0 Alt Color (with Symbiote Suit alt)
- C05: Web-Man (with Classic Black Suit alt)
- C06: Superior Suit Alt Color (with Symbiote Suit alt)
- C07: Classic Black Suit with Purple Rim (with Anti-Venom Classic Suit alt)
Complete Package Features:
- Full model imports for all suits
- Custom UI elements
- Series icon
- Custom name display
- Boxing ring announcements
- Wi-Fi safe (cosmetic only)
This is primarily a skin mod rather than a full moveset modification, meaning Spider-Man uses an existing character’s moveset (Sheik) but appears as the web-slinger. The visual quality is exceptional, with each suit rendered in detail that matches Ultimate’s art style.
The mod represents significant work in 3D modeling, texture creation, and game integration. All slots can be switched if you prefer different configurations, giving you flexibility in how you organize your roster.

Chun-Li
The First Lady of Fighting Games finally gets her chance to compete in Smash. Created out of the modder’s disappointment that Chun-Li wasn’t included as a full fighter, this comprehensive mod brings her into the game with extensive customization.
Comprehensive Integration:
- Replaces all Ken slots with Chun-Li
- Non-conflicting announcer call using patch3audio
- Custom name and fighter tip replacements
- Complete UI package
- Voice mod featuring authentic voice lines
- Custom facial expressions
- Final Smash and World of Light compatible
- Kirby hat for when Kirby copies her
- Custom swing bones for clothing physics
- Custom classic mode route
- Custom win animation by greenredmario
Technical Notes: This was the creator’s first attempt at implementing swing bones (physics for flowing clothing), which can look slightly janky in some animations. Despite this minor issue, the mod remains highly impressive and functional.
A single-slot version is also included for those who want Chun-Li without replacing Ken’s entire roster presence. The single-slot version requires either the one-slot effects plugin or manual deletion of the effects folder and config.json file to prevent crashes.
Chun-Li represents what many fans wanted to see in Ultimate, a second Street Fighter representative with completely different gameplay from Ryu and Ken’s shoto style.

I enjoy playing Modded Smash with my friends, especially with modded versions of Smash Ultimate. However, I recommend keeping the number of mods to a handful. Adding too many mods can significantly slow down the loading times on the Switch and increase the risk of crashes.
