Aggro is feisty, stubborn, and - true to her name - generally spunky. Frustrations as being the newest on the team have led to some bumps, but she always pulls through in the end and helps her friends. Despite her size, she hates being called little and will snap at anyone who does so.

Aggro tends to literally heat up when she is angry or upset, but she also has a warm and tender side that shows she cares for her friends despite her usual attitude.

Abilities and Skills


Firepower: Being a Fire Fury, Aggro is able to shoot balls or streams of fire with great precision. She can combine her blasts with other Fire Furies to produce a firework-like effect into the sky. Aggro can also concentrate her fire into a small blue flame, which can be used to draw on stone.

Increased Body Temperature: Aggro can heat up her body to a high temperature without flaming. The heat is high enough to cause her horns and parts of her scales to have an orange glow. This ability is also connected with emotions, and tends to manifest when she is angry or upset.

Smokescreen: Aggro is able to scrape her wingtips along the ground and create many sparks. This generates a copious amount of black smoke, which can obscure visibility.

Strength: Despite being a juvenile, Aggro is able to carry an adult human, with the extra weight of a heavy backpack, with no signs of struggle. After molting, she is able to carry Burple with the extra weight of the Belzium magnetized to him.


Rescue Riders

Aggro is a late addition to the team, and is first at odds with them when they accuse her of setting fires to scare sheep. She is skeptical of their rescuing mission at first, but decides to stay with them. In the beginning the Riders are not well integrated with her, causing her to feel left out, but after some trials, she becomes fully integrated into the group. She doesn't even leave to be with her own kind when the opportunity arises.

Cutter and Aggro are friends and group mates, but there appears to be occasional tension as Cutter tends to be annoying to Aggro, who has a quick temper.


Sometime after Elbone alerted Aggro of the dragon egg he found trapped in a thick lair of ice in the north and manages to free it with her fire, before falling into the ice and is unable to fly any of them back to Huttsgalor, the egg hatches and Aggro welcomes the newly hatched dragon to the world. Aggro is the main teacher and caretaker for Heatey, due to both being fire dragons. Just before Heatey left with Grumblegard, the two fire dragons exchanged playful firebreaths with each other.



  • Aggro is the only member of the Rescue Riders who didn't debut in the first episode of the series, "The Nest".
  • Despite her being angry about being called small she is the actually the smallest member of the Rescue Riders size wise.
  • In "The Bad Egg", before Aggro joined the Rescue Riders she came across Silver-tailed Ironclaw dragons.
