|“Too bad I don't have my powers. I would create a smokescreen to blind them while we steal it.”|
|— Ash, in Breakout!|
Ash is the current Elemental Master of Smoke and was a competitor in Master Chen's Tournament of Elements, alongside the other Elemental Masters of his generation. In the third round of the event, Ash fought against Kai inside a volcano, where he proved himself to be a dangerous adversary. After a long fight, Kai claimed the Jadeblade and defeated Ash. Afterwards, he was ridden of his powers and forced to work in Chen's Noodle Factory. Later, Ash would ally with the other Elemental Masters to reclaim their elements.
Ash and the Elemental Masters united against 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, Clouse released Nadakhan from the Teapot of Tyrahn. Infuriated over the destruction of his home realm, Nadakhan sought revenge on the Ninja and began trapping the Elemental Masters in the Sword of Souls to eliminate any opposition. At one point, Ash was imprisoned in the weapon offscreen, but after Jay made his final wish, recent events were erased and he was freed.
It's later revealed that he got another blade, thereby allowing him to stay in the tournament.
Ash was chosen to battle Kai in the third round of the Tournament. In the volcano, Ash got the upper-hand on Kai by disappearing and reappearing on the bridge, with the Jadeblade falling on the rocks below. Kai climbs under the bridge and attempts to kick Ash, but the Master of Smoke uses his powers to evade the attack by the Master of Fire. Kai continuously attacks Ash, with none of his blows landing while Ash keeps disappearing and reappearing and his punches landing, eventually sending the Master of Fire through the bridge and hanging precariously over the lava.
Kai flips himself back onto secured planks and uses his Spinjitzu to push Ash back, though the end result is the same. Kai then launches multiple fireballs, only for Ash to dodge them while they begin burning through the bridge. Ash manages to apprehend Kai, but he launches one more fireball in which he successfully burns through the last of the bridge, sending both of them onto the rocks below. The two then battle in midair over the Jadeblade, where they are shown to be evenly matched until Ash goes for the Blade.
Kai then attacks him, where he uses his powers to avoid being hit by the fire. Unfortunately for Ash, Kai uses this as his chance to take the Blade and end the match with Ash being eliminated and falling in a trapdoor.
Sometime after, Ash was stripped of his power and forced to make noodles for Chen in Chen's factory along with the other powerless masters.
Ash continued working until the Cultists shut down the factory and watched as Cole and Zane emerged from hiding as they explained their plan to escape the Noodle Factory through the sewer network. After Zane suggested they build a Roto Jet to blast their way out, Ash helped find spare parts throughout the factory.
Ash was later among the Elemental Masters as they rebelled against Chen and his Anacondrai cultists. When Kai destroyed Staff of Elements, the Elemental Masters regained their elemental powers and easily fought off Chen's forces, who would retreat while Ash and his comrades took control of the island.
Ash and the other elemental fighters battled with Chen's followers who were turned into Anacondrai. Later, cultists escaped with the intent conquering Ninjago. When seeing Kai and Zane awaken Elemental Dragons, Ash hugged Chamille, and later awoke his own Elemental Smoke Dragon and headed after Chen's army with the other fighters.
Ash used his Elemental Dragon to fly back to Ninjago City and was told by Lloyd to keep watch over the city.
Later on, Ash and the other Masters stand ready to hold off Chen and his forces, who have gathered in noodle trucks, but they are surprised when the trucks scatter to various locations. They each pursue a truck only to find them empty and realize Chen separated them to invade without hindrance. The revelation that they put many people in danger causes them to lose control of their elemental dragons.
After receiving a message from Neuro, Ash gathered with the Elemental Masters at the Samurai X Cave, where they discussed what to do about Chen before deciding to make their stand at the Corridor of Elders. Ash then fought in the battle at the Corridor of Elders against the Anacondrai Cultists before watching them being banished to the Cursed Realm by the spirits of the Anacondrai Generals.
At the end of the battle, he and the other Elemental Masters celebrate with the Ninja, promising to offer them future aid.
At some point, Nadakhan visited Ash, trying to remove all opposition. After Ash made three wishes, he was trapped in the Djinn Blade. Fortunately, as a result of Jay's final wish, Ash's meeting with Nadakhan not happened, thus freeing him from the blade with no memory of happened.
It is unknown where Ash and several other Elemental Masters were during Emperor Garmadon's rule and Ninjago City's takeover. It's possible he was captured during Ultra Hunt, or hid somewhere inside or outside the city, due to his absence in Lloyd's resistance team.
