Grimm the dragon is a big, ornery and mean magic animal of the antagonist Lady Kale. He is capable of breathing fire and is the only creature in the world that his icy and cruel mistress cares for. Kale's vehicle of choice is a "Dragon Wagon", carried by Grimm across the skies of Avalon.
In the show Edit
His mighty wings propel the Dragon Wagon vehicle carrying the evil Lady Kale (whose Jewel Armor is dragon-themed) and her pet magic animals, the dweasels Rufus and Twig, through the sky with tremendous mobility and speed. Fortunately for her good enemies the Jewel Riders, Grimm is stronger and faster, yet not nearly as intelligent as their unicorns. He is also not as agile as Princess Gwenevere's own flying Sunstar, however is capable of breathing yellow flame on command.
Sneering and snorting, the dragon creates a dark, sinister presence in the sky. Like Archie, he can talk on his own and not through a bonding jewel like the dweasels. Kale and Grimm are very close to each other, and he is utterly loyal and completely devoted to her. The otherwise cold and haughty sorceress affectionately calls him her "big baby" as he calls her "Mum-mum" (and even as Grimm smells nasty, according to Fallon, Kale tells him she likes the way he smells).

Between the events of the seasons one and two, Rufus and Twig temporarily relocate to the Dweasel Nook with Grimm after Kale's destruction in the episode "Full Circle" and before her return in "Morgana". Eventually, in the show's penultimate episode "Spirit of Avalon", Kale, Grimm and the dweasels all end up turned into statues by Princess Gwenevere and Ian, who use the combined magic of the Staff of Avalon and the Crown Jewels to defeat them forever.
Behind the scenes Edit
During the show's pre-production, Grimm used to have a goatlike beard, and more twisted horns. The Wagon was shown to be more crude-looking in some sketches.
