According to Fishlegs, Meatlug is 14 feet long, has an 18 foot wingspan, and weighs 5,724 pounds. She's dark brown in the film, but a lighter brown in tv-series. She's also covered in small purple spots. Meatlug's height is about the same as Gobber's but standing on her hind legs she is much taller as seen in the episode Animal House of Dragons: Riders of Berk.
Meatlug is the first dragon the teens are forced to battle during the Dragon training lessons. She downs all of them except for Astrid and nearly kills Hiccup. She notably does not even contemplate sparing him, but Gobber yanks her away just in time to save Hiccup. The teens continue to train with her throughout the film, and Hiccup's tactics, which he has learned from watching Toothless, work very well with her. At the film's climax, Hiccup taught his classmates how to ride the dragons before they flew off to rescue their tribe from the Red Death. Meatlug was ridden by Fishlegs. She fights in the battle, but gets discombobulated by the noise of the Viking shields. She spins out of control and lands on Fishlegs. That ends her part in the battle. She is seen again at the end of the film being ridden by Fishlegs. She and her rider race off after Hiccup as the new era of Berk begins.
Fishlegs is revealed to have chained up Meatlug, preventing her from leaving until Hiccup accidentally releases the Gronckle and she flies off with him. After the takeoff, Hiccup yells, "Meatlug?!", in surprise that Meatlug had not left. Meatlug did not acknowledge Hiccup until he yelled by taking her eyes off the sky in front of her to look at Hiccup in equal shock for a second before returning to flying. Inside the barn where Fishlegs kept Meatlug, he, Astrid, Snotlout, Ruffnut Thorston and Tuffnut discover that Meatlug is a she when they found her eggs in the hay. Until that point, the Vikings had thought that Meatlug was male, although apparently having noticed some behaviors more in line with female dragons, Fishlegs comments that "actually explains a few things".
Meanwhile Meatlug, with Hiccup on her back, flies to an island filled with dragons and their newly-hatched babies. There, Hiccup realizes this is where all the dragons come to lay their eggs. Hiccup manages to return all the dragons and their babies to Berk, where Meatlug immediately goes to feed her hatchlings which she left at the barn and is tackled by a happy Fishlegs. Meatlug presumably partakes in Snoggletog with her rider as Fishlegs is holding two of her babies.
In the TV series, Fishlegs and Meatlug establish a very endearing relationship, very similar in strength to Hiccup and Toothless' relationship.
Side-by-side, they express that they really care for each other and both appear to be extremely heartbroken when they had to leave each other.
Fishlegs tells a story to Meatlug, which involved Meatlug to fart an awful smell which Fishlegs quotes as: "Smells like rose petals." But despite his words he keels over and passes out from the terrible stench.
Fishlegs then developed a series of hand signals to give Meatlug instructions without needing to speak. Meatlug and the other dragons were able to scare off the Berserkers.
Meatlug then found a stone of good fortune, which was actually a Changewing egg. She then helped Fishlegs confront Snotlout and found the egg he took from the changewings.
Meatlug then helped the other dragons rescue Hiccup and Toothless from Alvin and his Outcasts.
Meatlug, when she and Fishlegs were dismissed from finding an Outcast ship because they were slow, Meatlug ingested a large amount of rocks, which allow her to create a lava pool that when dried up was stronger and lighter than iron, dubbed Gronckle Iron by Gobber. After she ran out, Fishlegs and Gobber gave her different rocks, accidentally giving her a magnet making her skin magnetic. Meatlug became frightened and ran out of the village after attracting different metal objects, including Hiccup's metal leg, and discovering the Outcast ship, Fishlegs and Hiccup used her magnetism to disarm the Outcast ship, sinking it in the process.
Meatlug felt neglected when Fishlegs spent time training with Iggy. During the competition, Meatlug found Alvin and the others spying on the teens. She was captured and used as a hostage. The Terrors were used to save her, and she was finally playing with Fishlegs after being rescued.
Meatlug then helped Fishlegs and Hiccup examine the Frozen Skrill that was found by the Berserkers. Meatlug and Toothless then tried to keep the Skrill at the Academy but escaped. Meatlug then held off the Berserkers while Hiccup took on the Skrill. After the Skrill and the twin disappeared, Meatlug and Fishlegs then searched for them with little success.
Meatlug then assisted Hiccup and the other riders in cleaning up Mildew cabbage field. When Stormfly and Hookfang started to act weird, Meatlug assisted Fishlegs in finding the cause, which was Dragon Root. After Stormfly cut it loose, Meatlug flew it out to sea.
Meatlug then assisted Fishlegs in his new job as a historian to Berk's children by carrying several of them. Meatlug then rescued Fishlegs, who was hypnotized into Thor Bonecrusher, from a wild Scauldron. Meatlug was then able to scare Fishlegs out his Bonecrusher personality and fly him away from the Scauldron. Meatlug then assisted Fishlegs in his search for Dark Deep by lighting the Dragon Eye with her Lava blasts, revealing the location.
Meatlug then assisted the other dragons and their riders in catching Silent Sven's sheep. She then assisted Fishlegs in building his ship for the Regatta.

However, After Drago's Bewilderbeast defeated hers, Meatlug and the others then followed its call. However, Meatlug and the other dragons were then freed when Toothless challenged the Bewilderbeast and became the new Alpha dragon. Meatlug was then reunited with Fishlegs and they resumed their participation in the dragon races.
Meatlug was used for training against new beginners as she attacked Fishlegs. Being her rider, Fishlegs and Meatlug are shown to be extremely close, to the point that their relationship is slightly odd; Fishlegs often refers to himself as Meatlug's 'Daddy'.

Later, he helped Fishlegs train her. Hiccup briefly rode Meatlug by accident, resulting in him landing on the Dragon Rookery. In episode The Eel Effect Meatlug 'hugged' and licked him. Hiccup's metal leg briefly became stuck to Meatlug when she became magnetized as he was trying to calm her down from her panic, resulting in him spending some time dangling from Meatlug until Fishlegs and Toothless were able to get her to expel the magnetic rocks.
Though their relationship has never been truly shown, it can be assumed they are on friendly terms. Toothless was shown to comfort Meatlug, like when Fishlegs was losing perspective in Worst In Show ,assisted her in keeping the Frozen Skrill from escaping, and she even helped him to be captured from having the Eel Pox to get the cure from their riders. Their relationship could be the same as their riders.

After that, she with Fishlegs and Gobber created Gronckle Iron. Later she was fed different types of rocks only to make her a living magnet. Later, when they caught her, Gobber tickled her again to spit out the magnetic rock. For thanks, Gobber made her a pair of earrings as a gift for producing Gronckle Iron. It can also be assumed that they are on good terms.
She shown to get a bit of bullying from Hookfang as she was frighted from his shadow from the episode of Dragon We Trust. But she has protected him from the Fireworms when he ran out of hot shots. She even got hit a few times from showing no concern for him at all as getting hit from his wing when he flew in the Dragon Training Academy and use his tail whip on her to get the sheep from her rider in the second film. Hookfang also helped in training Meatlug and Fishlegs to become fierce, as he got body slammed by her.

She was very lonely when her rider became hypnotized from Snotlout to become worthy Viking as she jumps on Stoick to lick him so she wouldn't too be lonely, as this could be another reason why she licked him because he might understand losing a best friend such as Thornado.
At first, Meatlug was very frightened by Tormentor when he took over Dark Deep itself, forcing all the Gronckles leave the island and migrate to Dragon's Edge. The situation made Meatlug upset and later on grew angry. Meatlug then trained with Fishlegs and Snotlout to take on Tormentor, though against Hiccup's advice. Soon on when Snotlout, Fishlegs and Meatlug ventured to Dark Deep, Tormentor faced Fishlegs and Meatlug head on. Meatlug, wanting to retreat as instinct, also wanted to return Dark Deep to the Gronckles. So Meatlug faced Tormentor, not till she realized that Tormentor was just lonely. So Meatlug gained a relationship with Tormentor, and even took a nuzzle to it.
