No discussion of Dragons: Race to the Edge - Season 3 is complete without praising the antagonist. Viggo Grimborn (voiced by the sublime Alfred Molina) evolves from a generic warlord into a Machiavellian chess master.
In Season 3, Viggo understands he cannot defeat the Riders by force. Instead, he uses psychology. He is no longer just hunting dragons; he is hunting Hiccup.
The mid-season two-parter, "Enemy of My Enemy," is a masterpiece of storytelling. Hiccup and Viggo are forced to team up against Ryker and the Dragon Hunters. The episode explores moral grey areas—Hiccup watches Viggo kill to survive, and Viggo sees Hiccup’s mercy as a weakness he cannot afford. By the season’s end, Viggo has lost the Dragon Eye but has learned how Hiccup thinks, setting up an even deadlier conflict in Season 4.
Season 2 ended with the Riders discovering the Dragon Eye—a sophisticated, spherical dragon encyclopedia and tactical device created by the legendary dragon rider, Bork the Bold. However, the device was useless without its power source: several colored lenses, each capable of revealing hidden dragon habitats, weaknesses, and strengths.
Season 3 picks up immediately from this cliffhanger. The central plot driver for these 13 episodes is the race to find the missing lenses before the villains do. This shifts the show’s structure from random exploration to a treasure hunt. Each lens (e.g., the Green Lens, the Blue Lens) leads the team to a specific, dangerous new island and a new dragon species.
Rating: 9/10
Season 3 of Race to the Edge is where the show finds its identity. It moves from "adventure of the week" to a serialized drama about leadership, sacrifice, and the cost of peace.
If you stopped watching Race to the Edge because the first two seasons felt repetitive, do yourself a favor and jump back in for Season 3. Viggo Grimborn is waiting, and he is going to break Hiccup before he makes him stronger.

Stay tuned for my Season 4 preview: "Who is the Dragon Hunter leader really working for?"
The fog around Dragon’s Edge was so thick you could barely see your own hand, let alone a Night Fury’s wing.
“Stay close, guys,” Hiccup called out, his hand resting on Toothless’s saddle. “Fishlegs, what’s the Dragon Eye saying? Are we close to the coordinates?”
Fishlegs squinted at the glowing cylinder, the light reflecting off his flight goggles. “According to the latest lens we recovered from the Ship Graveyard, the 'King’s Maw' should be right… here!”
Suddenly, the mist parted. Before them sat an island that looked like a jagged tooth rising from the sea. But it wasn't the terrain that stopped them cold—it was the sound. A low, rhythmic thrumming vibrated through the air, so deep it made the riders’ teeth rattle.
“That’s not a volcano,” Astrid whispered, patting Stormfly’s neck as the Nadder squawked nervously.
“And it’s definitely not a welcoming committee,” Snotlout added, though he gripped Hookfang’s horns a little tighter than usual.
From the shadows of the island’s central peak, a pair of glowing, amber eyes ignited. A dragon emerged, but it wasn't one they had ever seen in the Borg or the Dragon Eye's archives. It was a Submaripper, but twisted—scarred by Hunter chains and clearly guarding something. Behind it, half-buried in the rock, sat a cache of iron crates marked with the crest of Viggo Grimborn.

“Viggo’s been here,” Hiccup realized, his jaw tightening. “He’s using this dragon to guard a shipment of Dragon Root arrows.”
“Then we do what we do best,” Tuffnut shouted, leaning dangerously far off Belch and Barf. “We crash the party! With explosions! And perhaps a dramatic monologue!”
“Rough, Tuff, wait!” Hiccup yelled, but it was too late.
As the twins dived, the Submaripper roared, creating a massive whirlpool in the cove that began to suck the surrounding sea stacks—and the riders—downward.
“New plan!” Hiccup adjusted his flight suit. “Toothless, plasma blast on the rock overhang! We need to bury those crates before Viggo’s fleet arrives to pick them up!”
The battle was a blur of scales and fire. While Astrid and Snotlout distracted the disoriented Submaripper, Hiccup and Toothless zipped through the chaos. With a perfectly timed shot, they brought the cliffside down, burying the Dragon Root deep under tons of granite.
As the riders regrouped, panting and soot-covered, Hiccup looked back at the island. They had won the day, but the Dragon Eye showed more secrets stretching further into the Great Beyond.
“Viggo is getting smarter,” Hiccup said, watching the horizon. “But we’re getting faster.” The mid-season two-parter, "Enemy of My Enemy," is
Should we focus on a story about Viggo’s next mind game or an adventure where they discover a completely new dragon species?
Let’s address the dragon in the room: Hiccstrid.
Season 3 handles the Hiccup and Astrid romance perfectly. It isn't a dramatic, will-they-won't-they soap opera. It’s a quiet, mature realization. After a near-death experience involving an avalanche of ice and a very grumpy Speed Stinger, Astrid kisses Hiccup.
The beauty of this season is watching them navigate that change. They aren't suddenly different people; they are just two best friends who finally admit they are soulmates. The dialogue feels authentic—awkward, sweet, and utterly Viking.
The Dragon Eye itself becomes a symbol of the season’s central anxiety: the fear of running out of mysteries. Each new lens closes more doors than it opens. When the riders discover the “King of Dragons” (a future callback to the second film), they treat it not as a miracle but as a data point. The show is critiquing its own format. How many lost species can one archipelago hide? How many times can a trap be escaped? By season’s end, the riders have not expanded their world; they have merely annotated it.
This is where Race to the Edge transcends its “filler” reputation. Season 3 is an anti-expansion. It argues that growth is not always outward—sometimes it is the painful recalibration of goals. Hiccup does not discover a new island in the finale. He discovers that his friends are tired. That Astrid misses simple flights without strategy. That even Toothless seems bored during reconnaissance. The season ends not with a roar but with a campfire. The characters sit in silence, watching the sea. The war continues, but the meaning of the war has dissolved into maintenance.
By the time you finish Dragons: Race to the Edge - Season 3, the "teenagers" are gone. They have become warriors.
Debuting in the episode "Scuttle of the Triple Stryke," this dragon is a scorpion-like Stoker-class dragon with three tails, retractable venomous stingers, and the ability to cause excruciating pain without killing. The Riders initially see it as a mindless beast, but the episode delivers one of the season’s most touching subplots: a feral Triple Stryke bonds with Snotlout. This forces Snotlout to grow beyond his egotistical persona to become a compassionate rider. The Triple Stryke is so popular that it later appears in Dragons: Dawn of New Riders.
Season 3 begins with the Riders using the Dragon Eye to discover new dragon species and their nesting grounds. However, each episode’s discovery attracts the attention of a ruthless dragon trapper named Captain Ryker (Viggo’s more brutal, less strategic older brother) and a cunning new villain: Mala, a queen from the secluded Defenders of the Wing tribe—who believes dragons are sacred weapons, not friends. She wants to control the rarest dragons before Hiccup can “befriend” them.
The season’s emotional core: Hiccup struggles with leadership as the Riders split into teams to protect multiple dragon nests at once, while Astrid uncovers a dark secret about her family’s past involving dragon hunters.
