Funguys Swarm Characters Hub

All Characters

Every playable character in Funguys Swarm has unique default weapons, elemental affinities, and playstyle focuses. Understanding these differences is essential for choosing a character that matches your preferred playstyle and for building effective synergies around your character’s strengths.

Funguys Swarm characters can be broadly categorized into three playstyle archetypes. Aggressive characters like Fuzzbug and Chimpy reward players who stay in the middle of combat and stack damage multipliers. Defensive characters like Ersa reward careful positioning with strong crowd control. Versatile characters like X-olotl adapt to whatever skills and relics appear during a run.

Ersa — Water Control Specialist

Ersa is a Water-element Funguy with Freeze-based crowd control as her defining feature. Her default weapon applies Freeze to enemies on hit, significantly slowing their movement and attack speed. This makes Ersa exceptionally good at controlling arena space — enemies frozen in place cannot advance on your position, giving you time to deal damage or reposition.

Ersa is the recommended character for all new players. Her Freeze effects are easy to understand and apply, and they remain effective throughout all five arenas. As you progress to later arenas with higher enemy density, Ersa’s crowd control becomes increasingly valuable for managing chaos.

Ersa’s Beast affinity means she scales well with Beast-element upgrades. Combining her natural Freeze control with Beast damage amplification creates a strong all-around build that works in every arena.

Fuzzbug — Beast Summoner

Fuzzbug summons orbiting Beast-aligned pixies that attack nearby enemies automatically. The pixies deal consistent passive damage without requiring you to aim or position specifically, making Fuzzbug a strong choice for players who want to focus on movement and dodging rather than active damage dealing.

The 1.0 update significantly improved Fuzzbug’s pixie scaling. Each Beast-element upgrade now increases pixie damage more substantially than before, making Fuzzbug one of the strongest late-game characters when built around Beast synergies.

Fuzzbug’s weakness is early-game vulnerability. Without enough Beast upgrades, the pixies deal insufficient damage to clear enemies quickly, and Fuzzbug’s base stats do not provide enough survivability to compensate. Players choosing Fuzzbug should expect a challenging first few arenas before the build comes online.

X-olotl — Clone Striker

X-olotl creates clone copies that mirror your weapon attacks. More clones mean more instances of your weapon firing simultaneously, effectively multiplying your damage output by the number of clones you have active.

X-olotl’s strength is flexibility. Clones mirror whatever weapon you are using, meaning X-olotl can benefit from any weapon upgrade without being locked into a specific weapon type. This makes X-olotl the most adaptable character for experimental builds.

The weakness is that clones require attention to positioning. Clones do not move independently — they remain where they were summoned. Maintaining effective coverage requires repositioning periodically during combat, which can interrupt your rhythm in high-intensity situations.

Chimpy — Earth Retaliator

Chimpy delivers retaliation damage when enemies attack you while your retalia ability is active. The retalia area scales with enemy aggression — the more enemies attacking you simultaneously, the larger the retaliation zone becomes.

Chimpy’s playstyle rewards standing your ground rather than running away. When surrounded by elite enemies, Chimpy’s retaliation damage can exceed what any other character could achieve in the same situation. However, in early arenas with lower enemy density, Chimpy’s retalia rarely triggers, making the character feel underpowered compared to the starting four.

Chimpy is an Earth-element character, making Earth and Water the most natural element choices for his build. Earth skills amplify his retalia area, while Water Freeze effects provide crowd control to keep enemies in the retalia zone longer.

Groovba — Nature Poisoner

Groovba is a Nature-element character focused on poison effects and healing. His poison skills apply stacking damage-over-time effects on enemies, while his healing passives keep him alive through extended arena runs.

Groovba unlocks after completing Carrot Farm five times, making him one of the first unlockable characters available. By the time you unlock Groovba, you will have enough Forest Strength upgrades to make the early-game difficulty manageable.

The Nature element’s focus on poison, summons, and luck modifiers creates a distinctive playstyle that rewards patience. Groovba’s poison stacks deal increasing damage the longer enemies remain alive, making him effective against tanky elite enemies but less effective against bosses that die quickly.

Dr. Botanika — Sky Sentry Controller

Dr. Botanika commands Ube, a robotic sentry that carries and fires your weapon independently of your movement. Ube automatically applies Shock to nearby enemies every three seconds, creating a passive crowd control effect that complements any weapon build.

Dr. Botanika’s unique feature is the separation of movement and damage. While you focus on dodging and positioning, Ube handles dealing damage automatically. This makes Dr. Botanika one of the easier characters to play effectively at high difficulty levels.

The Sky element affinity focuses on mobility and shock effects. Dr. Botanika naturally synergizes with Sky-element skills that enhance Ube’s capabilities or improve your own movement speed. The Shock effect from Ube also amplifies well with Water Freeze chains — Shock slows, Freeze stops.

Dr. Botanika, Mr. Midnight, and Steve were all added in the 1.0 update and each represent a different approach to the Ube sentry mechanic. Understanding how Ube interacts with different element and trigger combinations is key to maximizing these characters.

Mr. Midnight — Night XP Scaler

Mr. Midnight uses Ube’s magnet to collect XP automatically from defeated enemies, granting stacks that increase damage by one percent per Night Card owned. This creates a feedback loop where kills generate XP, which generates stacks, which generates more kills.

The Night element focuses on spellcasting and projectile-based builds. Mr. Midnight’s stack mechanic rewards aggressive play — the more you kill, the stronger you become. This makes him one of the highest ceiling characters in the late game when enough stacks have accumulated.

The risk is the early game. Without stacks, Mr. Midnight deals less damage than other characters. Building up the stack count requires surviving the first few arenas without the damage bonuses other characters have from the start.

Steve — Water Automation Specialist

Steve automatically chooses card upgrades with a preference for Water cards. His passive grants five percent Luck and Chance increase per Water Card owned, making Water-focused compositions significantly more consistent on Steve than on other characters.

Steve’s automation takes the guesswork out of upgrade choices — you no longer need to weigh options during level-ups because Steve always picks Water cards when available. This reliability makes Steve one of the most consistent characters for executing specific build strategies.

The Water element provides Freeze, pushing, and sustained control effects. Steve’s Luck bonus makes Water Freeze effects appear more frequently, and his Chance bonus improves the odds of getting beneficial card effects during runs.

Secret Character

The secret character is unlocked by completing the full game — specifically defeating the Fire King in the Hellscape arena. The secret character has a unique default weapon and elemental affinity not shared by any other character. Community guides recommend attempting the secret character unlock only after you have at least five Forest Strength levels and a tested Fire King strategy.
