|“||Greetings, young lady and good day to you. Fear not, I am Longg, the Dragon Kwami.||”|
—Longg, "Ikari Gozen"
Longg is currently dormant in her Miraculous within the Miracle Box, being kept by Marinette Dupain-Cheng. When the situation requires it, she temporarily becomes active to help Kagami Tsurugi transform into Ryuko.
Longg is 10 centimeters (or 4 inches) tall and red with four black horns on his forehead: a black horn on each side of his face, and red horns from the upper back of his head with black spirals. Additionally, Longg has golden eyes, a whisker on each cheek next to his mouth, two small black spikes on his lower back, and a long tail with three black tips at the end.
Longg is a bit formal, calling Kagami "young lady", has an eloquent approach and is quite informative and patient explaining his powers. he has a tendency to ramble on a bit, not seeing that her wielder is trapped inside an akumatized villain, but knows not to rush as he tried to tell Kagami Ladybug's plans.
Longg can fly, levitate, and phase through solid objects. She can also carry objects that are larger and/or heavier than her.
As a kwami, Longg is able to transform the holder of the Dragon Miraculous into a dragon-themed superhero.
Longg gives the wearer of the Dragon Miraculous the power to use the elements of water, wind, and lightning. The wearer can transform into one of these elements by saying either water, wind or lightning dragon. After all three elements have been used, Longg loses energy, giving the wearer five minutes until they transform back. Longg can fuse her powers with Tikki's to create the hybrid wielder, Dragon Bug.
As Longg and Kagami meet, she tells her the abilities she will grant her as Ryuko, but she is cut short as Kagami activates her before Longg can fully inform Kagami of Ladybug's plan. In "Heart Hunter", she is happy to see Kagami again.
Longg knew Ladybug's plan to defeat Ikari Gozen, as she had tried to tell it to Kagami before she activated the miraculous, indicating that Ladybug might have gone over it with Longg before sending the Dragon Miraculous Kagami's way. The fact that she knows the kwami's name when she asked Ryuko if Longg had indeed gone over their plan with her is further indication of this.
Marinette puts on Longg's Miraculous in "Kwamibuster", so she and the other kwamis can help her save Tikki and Plagg from the titular villain, while she uses the power of the Mouse Miraculous to become Multimouse. The Dragon Miraculous is one of the few Miraculouses that the temporarily mouse-themed heroine didn't use, but she did hide herself in the kwami's mouth for a short time. In "Heart Hunter", because of Marinette's failed sabotage attempt, Longg was the only other kwami that was saved from Hawk Moth's grasp. After the events of Miracle Queen, Marinette became the new Guardian tasked with safeguarding Longg's Miraculous, along with the rest of the Miraculouses.
Before Season 2
When the concept of Perfection came into existence, Longg came into existence. Before the Miraculous jewels were created, Longg and the other kwamis traveled all over the universe unable to interact with humans. Then, thousands of years ago, a mage created the Miraculouses. She started out in China. When her Miraculous was not being worn, Longg was dormant in the Dragon Miraculous, which was stored inside the Miracle Box.
During Season 2, Longg was dormant in the Dragon Miraculous.
In "Sandboy", Longg was celebrating Nooroo's birthday in the Miracle Box with the other kwamis, and they were excited when Tikki and Plagg arrived. The kwamis marveled at the gift Tikki brought, a marker, and played with each other. When the time to find Nooroo came, Longg got into position in an effort to contact him, but the kwamis contacted his wielder instead. Upon hearing his voice, the kwamis shuddered at the thought of being his slave and prevented themselves from being discovered when they all cut off the connection. They realized if they contacted Nooroo's wielder, rather than Nooroo, then someone must have been akumatized and that Tikki's and Plagg's wielders would be in danger.
During Season 3, Longg was dormant in the Dragon Miraculous.
In "Ikari Gozen", Longg and her Miraculous were loaned to Kagami as a "special delivery" from Ladybug. Upon meeting her, she tried to explain her powers and Ladybug's plan to her wielder but became surprised when Kagami said the magic words, instantly transforming her into Ryuko, before she could divulge Ladybug's plan fully. After the trio saved her wielder's mother, Longg and her Miraculous were returned to Ladybug and then to Master Fu.
In "Kwamibuster", she was activated along with the other kwamis to help Multimouse enact her plan of rescuing Tikki and Plagg. During the confrontation, she revealed Multimouse to a disguised Cat Noir, who informed him of Ladybug's plan. However, Longg was one of the few kwamis captured, but this was actually part of the plan as she unveiled her stowaway wielder, and with the help of Multicat, Lonng was eventually set free. After Kwamibuster's defeat, Longg and the others cheered for Marinette as their plan was a success and was returned to Miracle Box.
In "Heart Hunter", she was once again loaned to Kagami. Once again reactivated, she was happy to see Kagami again and transformed her into Ryuko so she could aid in the fight against Heart Hunter. After the titular villain was deakumatized, Longg and her Miraculous were returned to Ladybug. Unaware of what happened to the Guardian, she was also unknowingly saved by the heroine.
In "Miracle Queen", after avoiding Miracle Queen's hornets, Longg was reactivated again by Ladybug, and after recharging, she was ready to help. She fused her powers with Tikki's, transforming Ladybug into Dragon Bug, and combined the power of the Water Dragon and the Yo-yo to form a water barrier, protecting the heroes from Miracle Queen's hornets. After fighting the titular villain's minions and deakumatizing her, Longg defused with Ladybug. After regaining the Miracle Box, she returned to her Miraculous.
