Arin

Arin is a self-taught Spinjitzu prodigy, creator of Object Spinjitzu. 
He is the first known person to teach himself Spinjitzu without a master. 
He used to live in a neighbourhood outside a city, until the Merge caused his parents and region to dissappear. 
After the Merge, Arin and his best friend Sora became students of the N.I.N.J.A.S. after saving a dragon called Riyu. 
With the help of the Elemental Alliance, Arin helped to free most of the dragons from Imperium. 
He and Adam searched for the Pink Dragon Core, defeat Beatrix, and helped to stabilize the Merged Realms during the MergeQuake Storm, where he saw his parents through a rift.
His popularity as a ninja continued as he took down the Mechanic and rescued Lobbo from his mech along with Adam, as well as attending Sora's dance party, until Cinder stole the Mallet of Shattering and broke Wyldfyre's leg before accompanying Adam in order to learn the Rising Dragon technique from a dragon named Egalt. 
However, he began to express frustration at not improving his Spinjitzu which ultimately led to Egalt demoting him to be taught under another dragon named Rontu. 
When the Blood Moon arose, interrupting their training, Arin and Riyu end up separated from the ninja in a storm caused by Jordana before rescuing Bonzle from her, only to lose the latter to Ras. 
Regrouping with Adam and Ian, Arin made his way to the Shadow Dojo, where the Ritual of the Blood Moon occurred, and Nick was sent to the Nether-Space, until Arin (with discreet assistance from Sora) stopped Ras before the moon then passed.
In the Tournament of the Sources, Arin met his childhood friend Frak, who he discovered had fallen under the sway of Ras while searching through Ras' room. 
After the latter found out Arin invaded his room, Ras tempted him by revealing that Wu was responsible for the Merge, and that Sora lied to him. 
His relationship with the ninja and Sora began to break down and he became distant, his faith in the ninja crumbling slowly. 
Because of this, Arin went to Frak for help with mastering Spinjitzu, Frak helped Arin do so with Ras' teachings, and Arin helped Frak avoid the corruption of the Wolf Clan and Shatterspin. 
Near the end of the tournament, Arin used his parents' detective game history as an advantage to figure out that the tournament was rigged by Bleckt, who had allied with the Wolf Clan. 
At the end of the tournament, as the rest of the Forbidden Five were freed and Arin managed to do a full-fledged Spinjitzu, Nokt was stripped of the powers he stole and escaped with the other members while taking Ras along to continue their revenge. 
Arin abandoned the ninja and chased after the Five to protect Ras. 
Arin and Ras became marooned in another realm, and he helped nurse Ras back to health with intentions of finding his parents.
== Appearance ==
Arin has coily black hair in "The Duke" hairstyle, featuring stubbled sideburns and two scars on his right cheek. From "The Merge: Part 1," to "Return to Imperium," "The Battle of the Second Monastery," and "What the Mech?," he wears an orange sweatshirt with a dragon on it and his initial 'A' in Ninjargon in white, located above the left pocket, navy blue pants also sporting his initial in a lighter color on the right pocket, a very bright celadon belt, and black gloves. In "The Merge: Part 1," he wore Lloyd's mask with his clothes, but neglected to wash it as it had a dirty appearance, as noted when he gave it back to Lloyd in "The Merge: Part 2." After escaping Imperium, Lloyd gave it back to him in "The Battle of the Second Monastery."
On the day of the Merge, as a child, Arin was smaller and wore a different orange sweatshirt, but with the initial in the very centre, different navy blue pants, and black gloves.
From "Return to Imperium" to "The Battle of the Second Monastery", Arin dons the disguise of an Imperium citizen under the alias of Dr. Lampshade Floortile, with three markings on his left cheek.
Sometime prior to "The Temple of the Dragon Cores," Arin changed into his own ninja suit, consisting of orange colouring, but retains his sweatshirt and celadon belt.
== Personality ==
Arin was once an ordinary child who aspired to be a hero. 
However, after the Merge, he underwent a significant change. 
When he believed that the Elemental Alliance had vanished, he striven to take on the role of protecting the world, gaining his parents' pride, and continuing their legacy. 
Despite his noble intentions, Arin faced several challenges in his ninja journey due to his lack of coordination and finesse compared to his peers. 
This often resulted in clumsy mishaps, such as self-inflicted punches.
Season 2 explores Arin's struggles as he grapples with his skills. 
He tries to control them while feeling the weight of expectations to become a skilled ninja. 
Arin's accident, which injured Egalt, his lack of Elemental Powers, and the looming threat of Ras, compound his insecurities and self-doubt from Season 1, intensifying his internal struggles. 
The fear of inadequacy and the need to prove himself in the face of adversity deepen Arin's inner conflicts. 
These conflicts are especially evident during a battle orchestrated by Ras, where his vulnerabilities and doubts were exposed.
After being told by Ras that the Alliance were responsible for the Merge and Wu confirmed it, Arin started to become cold and determined to side with Ras to find his parents, which helped improve his Spinjitzu.

Arin's potential to have mastered multiple variations of the martial art was evident from Adam's remarks in "The Merge: Part 2" and "Gangs of the Sea," where he acknowledged the existence of additional hidden Spinjitzu powers within Arin, with Object Spinjitzu being one of them.
