|“How are we supposed to stop them? Most of us have lost control of our Dragons. Not to mention we're outnumbered ten to one!”|
Gravis is the current Elemental Master of Gravity and was a competitor in Master Chen's Tournament of Elements, alongside the other Elemental Masters of his generation. In the second round of the event, Gravis fought against Griffin Turner, who used his element to claim the Jadeblade—beating Gravis. Afterwards, he was ridden of his powers and forced to work in Chen's Noodle Factory. Eventually, Gravis united with the other Elemental Masters to reclaim their elements.
Gravis and the Elemental Masters united against Master Chen, who completed a spell that transformed him and his followers into fake Anacondrai. Consequently, an ancient conflict was renewed, as the new alliance of Elemental Masters fought Chen's army at the Corridor of Elders before Garmadon sacrificed himself in a bid to banish their adversaries to the Cursed Realm.
Months after the war's end, Nadakhan began trapping the Elemental Masters in the Sword of Souls to eliminate any opposition. At one point, Gravis was imprisoned in the weapon offscreen, but after Jay made his final wish, recent events were erased and he was freed.
Gravis was one of those invited to participate in the Tournament of Elements. He accepted and met the other Elemental Masters on the New Ninjago City pier at midnight where they were picked up by Clouse to be taken to Chen's Island. While on the ferry, Gravis meditated while using his powers to make nearby objects float.
After arriving on the island, Gravis met Master Chen and settled into his room in Chen's Palace. When first round begins, Gravis obtained a Jadeblade by taking the one Cole won from Paleman after he raised it in a moment of triumph. After Gravis gave the blade to Chen, he was advanced to the next round of the tournament. He later cheered when Karlof was shown to have the last Jadeblade and cheered louder after Kai outsmarted Karlof and won.
Next day, Gravis was announced as the second competitor of the first match, where he fought against Griffin Turner to obtain a Jadeblade from a cherry blossom tree. Although both had an even start, Griffin began to annoy Gravis by running around him and using the branches to knock him off balance: Gravis then buried the Master of Speed using the blossoms. He then levitated the Jadeblade towards him, but unfortunately, Griffin grabbed it first, knocking the Master of Gravity out of the tournament. Chen then activated a trapdoor, which Gravis laughed at since he was still levitating, though fell in when Chen pressed a button that somehow dropped a sandbag on him. After that, Chen took away Gravis's element by Staff of Elements and sent him to Noodle Factory.
After the factory was put on lockdown, Gravis and the other imprisoned masters gather around Zane and Cole explained their plan to use the sewer pipes to escape, though the plan was foiled thanks to the arrival of Dareth. After they decided to build a Roto Jet to blast their way out, Gravis searched the factory for usable parts.
Gravis helped with building the Roto Jet and after it was completed he join the others in subduing the guards and escaping the factory. Later, they broke into a room with skeleton remains, where they rescue Nya and Garmadon from Anacondrai Serpent by shooting at rocks, that later fell on it to death. They soon break into Chen's ceremony room, where they disrupt his spell to turn into Anacondrai and battle the Cultists. When Kai destroyed Chen's staff, Gravis's element returned to him and he helped his allies in defeating Chen's followers, but Chen and a few henchmen escaped. Later, Gravis and Griffin Turner took out captured Chen's henchmen from the palace and took control of the island.
Gravis and the other elemental fighters still guarded captured Chen's followers, and then battled them when they turned into Anacondrai. After elemental masters locked up in palace, Chen and his army escaped with the intent conquering Ninjago. When seeing Kai and Zane awaken their Elemental Dragons, Gravis awoke his own Elemental Gravity Dragon and headed after Chen's army with the other fighters to Ninjago.
Later, Gravis and the other Masters stand ready to hold off Chen and his forces, who have gathered in twenty noodle trucks. However, the trucks began heading in various directions to presumably attack the villages, Gravis pursued one of them, only to find it empty and realize Chen separated them to invade without hindrance.
Like many others, he lost his dragon because of fear and was left stranded as Chen invaded without problem.
After receiving a message from Neuro, Gravis met up with the other masters in the Samurai X Cave. There, Gravis questioned how they would be able to stop Chen's army as they no longer were able to control their elemental dragons. Eventually, they decided to make their stand against Chen's army in the Corridor of Elders. During the battle in the Corridor, Gravis fought bravely against the fake Anacondrai, and when Chen caused one of the statues to fall on the people of Ninjago, Gravis used his power to move it out of the way, saving many people' lives.Following the Cultists' banishment to the Cursed Realm by the souls of the released Anacondrai Generals, Gravis celebrated with the other masters when victory was achieved. He later promised to help the Ninja with any problems they might face in the future.
At some point, Nadakhan visited Gravis, trying to remove all opposition. After Gravis made three wishes, he was trapped in the Djinn Blade. Fortunately, as a result of Jay's final wish, Gravis's meeting with Nadakhan not happened, thus freeing him from the blade with no memory of happened.
It is unknown, where Gravis and several other Elemental Masters were during Emperor Garmadon's rule and city's takeover. Probably he was captured during Ultra Hunt, or hided somewhere inside or outside the city, due to his absence in Lloyd's resistance team.
