As Saint: Rubicon

Firebugs are arthropod-like creatures found only in Rubicon. They are initially passive but become fast and aggressive when provoked.


Firebugs resemble insects with thin bodies and antennae that curl toward the ends. They have 2 sets of legs, 2 antennae, and 6 detachable Fire Eggs. When their 'eggs' are detached, they reveal 6 Fire Spears underneath. They have 2 large eyes and round, bulbous heads that are wider than their bodies. Their 'eggs', eyes, and Spears are the same color, which varies between pink, red, and orange. Their bodies are usually dark with a gradient in one of the aforementioned colors.



Though Firebugs are initially passive, they explode and drop their Fire Eggs when attacked, then begin hunting nearby creatures. They do not take damage while their Fire Eggs are still attached; after losing this immunity, they require around 2 Spear hits to kill.

An efficient way to kill them is to stick a Fire Egg to their body, then hit them with any other weapon to disable their damage immunity before the Fire Egg detonates.

Like other arthropods, Firebugs can be killed with a Spore Puff. This dispatches them easily, as it does not activate their aggressive state; however, there is limited use for this, as Spore Puffs do not spawn in Rubicon.


Firebugs are difficult to evade over dry land once aggravated, but they cannot swim. By luring one into water or void fluid or swimming down and away from it, they can be easily avoided, though they will still be aggravated. Slugcat can also jump to evade their attacks. Finding a Shelter and resting in it resets their behavior back to neutral.


Firebugs drop 6 Fire Eggs when hit and 6 Fire Spears on death. Fire Eggs can be eaten for 1 food pip 🌕 each or thrown and detonated. The explosion radius is large enough to fling and stun nearby objects or creatures. Fire Spears deal more damage than standard Spears and are the only Spears that Saint can use.

Abilities & Behavior

A Firebug in their aggressive state

When not aggravated, Firebugs roam around passively and generally ignore other creatures. They are initially immune to all sources of damage; upon taking the first hit, the damage is fully negated, and their 'eggs' pop off with an explosion that knocks back nearby creatures and can trigger explosives. This leaves them vulnerable and causes them to become hostile to most other creatures, regardless of the source of damage. In this aggressive state, they move faster and attempt to dodge thrown weapons by jumping. They can climb poles, walls, and ceilings.

Variants & Attributes

A Firebug's eyes, Fire Eggs, and Fire Spears are all the same color and can range between yellow, orange, red, and hot pink. The length of their antennae can vary.


  • The Firebug's aggressive state is easily missed during Saint's campaign, as they can be quickly dispatched via ascension by the time they are first encountered.
  • Challenge 54 'Flaming Pursuit' forces Saint to fight four of them without their ascension ability, which showcases their danger when enraged and the utility of their Spears and 'eggs'.
  • Because of their lack of grab animation, they can easily bypass pipe-juking invulnerability and catch the player as soon as they exit a pipe.
  • If Saint ascends a Firebug they are holding, they may die or get knocked out of bounds by the explosion.
  • If Saint grapples a Firebug with their tongue, the Firebug will behave as if they were attacked.
  • Firebug Eggs and Spears have a wider range of possible hues than Firebugs. This extra color range is not seen in-campaign, however, as these objects can only spawn attached to Firebugs, from whom they take their color.
    • This expanded range can be seen with crafted Fire Eggs in Gourmand's campaign, but it is not possible to see Fire Spears' full range outside of Arena.
