I love Grenukers slugs.

Grenuke slugs are common grenade slugs similar in appearance to Hop Rocks. Grenukes are known to sleep for long periods of time on the ceilings of caverns that will awaken and fall if they hear loud noises or other disturbances.

A famous Grenuke is Sparky, who belongs to Eli Shane.

A ghouled Grenuke is called a Greneater.

Preferred Habitat

Grenuke slugs preferred habitats are rocky plains like Quiet Lawn Cavern.


In both Protoform and when transformed, Grenukes have tan skin, and a green shell that has a dark green grid.

When transformed, they're same in color compared to their Protoform. They gain armor on the edge of their tail, their hands, and on their arms. When fired, they emit sparks like weak fire and their tails will especially emit sparks when about to explode.


  • Protoform Abilities - Shoots sparks.
  • Mushboom - Timed explosion, powerful targeted blast with a mushroom cloud.
  • Nuklock - Grab and hold tight to almost any surface/target (including slugs and slingers alike) before it explodes.
  • Spikesploder - Shoots segments from its body as it flies, segments stick to walls and explode in tandem.
  • Megamorph Abilities - Shoots grenades. 

Fusion Shots

  • Frostbomb - "Frostcrawler"+"Grenuke" - TBD. It hasn't officially debuted in the series yet.
  • GrenukeSlam: "Grenuke"+"Rammstone" - That creates a spinning disk that destroys anything in its path.


A slug that lives up to its name, the Grenuke is more grenade then slug. Mushboom is a common offensive attack when trying to explode obstacles (rock walls, doors) or opponents. Nuklock is good for precision damage as the Grenuke will hold onto the target until its either knocked off or it explodes. Spikesploader is good with indiscriminate damage but can also be focused if the slug aims correctly.

Grenukes can also be used in rapid-fire slinging if the precision when finding a target of destruction isn't important. Overall, they're an important destructive force.



  • Grenukes are both designed and named after grenades, a well known explosive.
  • In the episode The Slugout, it is called a Grenuker instead of Grenuke.
  • In an earlier version of Battle For Slugterra, Eli's named slug is mistakenly called Banger (Eli Shane's Armashelt), when it should've been called Sparky. It was corrected soon afterwards.
  • People in Quiet Lawn Cavern keep silent because they live under a colony of Grenuke Slugs that rest on the roof of the colony. If disturbed or scared by noises, the Grenukes could fall from their sleeping place, activate, and cause explosions.
    • However, during the first Slugout between Eli and Billy, they do not look bothered at all by the noise of the duel and keep sleeping. They do activate later when Pronto throws a Sonic Snare, that produces a low sound, against the Slugs. This caused many of them to scream, fall from their sleeping place, and activate their explosive power.
      • This could mean that these Slugs hear a different range of noises from humans, like dogs or other animals can hear ultrasounds and/or infrasounds, that humans cannot hear.
  • Unlike the rest of the fire Slugs, the Grenuke Slug has no red in its color scheme.
  • A Megamorph Protoform of the Slug is seen in The Lady and the Sword, Slugterra: Into the Shadows, and the Slugisode "The Good, The Bad, and The Larry". Its Megamorph Velocimorph debuts in Slugterra: Slug It Out! but hasn't debuted in the show.
