As such, when Tom duelled Nemico and the evil version of Tom matched the true warrior of Avantia admirably, Tom resorted to summoning Ferno to assist him. These claws are sharp enough to draw blood from Arcta and make significant gashes in Ferrok's chest.

Epos moved over Ferno, dropping down and grabbing the dragon's horns with her talons, pulling his head around until Ferno reared up and slashed with his claws. When Aduro approached Tom about participating in the Battle of the Beasts to protect the Book of Worlds, Tom was given the option to choose a Good Beast of Avantia to fight alongside him. After Tagus was forced to withdraw from battle with Kyrax, Tom summoned Ferno to battle due to the Beast's fear of molten metal and fire. Note this section focuses on appearances from the Battle of the Beasts trilogy, which is potentially non-canon.The two Beasts scrapped on the ground, with Ferno using his fangs and claws to match Ferrok's attempts to bind him. The Fire Dragon lives in a cave in the mountain range near the Winding River, the main source of clean water for southern Avantians, with one of the main duties of Ferno being ensuring the river continues to flow to ensure the citizens have enough water to survive. By the time they were ready to battle, Trillion, Vipero and Claw had fused to become the Super-Beast. After crossing over the Forbidden Land, the Fire Dragon opened the portal to Drakonia, appearing over the Lava Sea. The Beast was targeted by Malvel and brought under the dark wizard's control due to a dark magic collar being fastened around his neck, and contributed to the corrupted Beast's attempt to bring Avantia to its knees so Malvel could take power.

As the Evil Beast began to rise from the lake, Ferno began to spew flame over the water, meeting water being released by Sepron in a hissing impact. The Fire Dragon patrols the river and makes sure the southern towns of the kingdom are never flooded. Ferno was the last of the three to arrive, swooping over the ocean as Epos released a fireball on Grashkor, temporarily taking him out of the fight, blinking an eye in greeting, and tipped a wing to the Avantians to allow them to climb on. He began to advance on Nemico, eventually forcing him off of the cliff, although he was caught by Tom, merging them and restoring Tom's whole soul. He was later awoken by Lyra using the potion she and Daltec had developed to reverse the spell as Daltec awoke Sepron.As the Beast still writhed, Tom entered and turned the key, causing the collar to vanish and release Ferno. Ferno's voice flitted in and out of Tom's mind through the Red Jewel and his scale as angry and confused whispers, mixing and merging with the voices of the other Beasts.
