Description
Sentinel Arc's power-based form, a potential that he unlocked from his Sentinel Gear system throughout his crusade against the Metal Empire's Null Process. This form granted him enhanced strength and greater defense, capable of both tanking and delivering heavy attacks. After his fight against the hijacked JL-Sisters, this form can be equipped with JL-Arms, though Command Beetle is best suited with JL-1 Command Shield and JL-2 Command Blaster.

Nikola Adhitya is a young man who was turned into a cyborg augment by the Null Process, rulers of the elusive Metal Empire who seeks to turn the entire world into one singularity where human will is obsolete. Niko vowed to avenge his father Sinclair, and began his crusade to destroy the Null Process once and for all.
Throughout his journey, he was helped by JL-9, a peacekeeping android who referred herself as Jennifer "Jenny" Linwell, and her mother Dr. Vesta Linwell, a renowned engineer of Jayabumi. While he and Jenny were navigating through their daily school life in Jayabumi High School (JB High), they met the Campbell brothers, Brandon and Timothy "Timmy" Whom they befriended, gaining more allies in their crusade against Null Process.
Initially preferring to work solo, Niko as Sentinel Arc was rather brutal and relentless when it comes to dealing with Null Process Drones (NPDs) himself. He kept on searching the whereabouts of Sable Prime to no avail, which at times frustrated him as the Drones refused to hand him valuable information willingly. Compared to Jenny who preferred to secure the citizens first and earn their recognition, Niko cared less about others' recognition, preferring to work in the shadows and get his job done.
Beneath that rough exterior however, is a gentle heart who wishes no harm towards innocents. He believed that the burden of fighting the Null Process lies on him and him alone, all so he could keep others away from getting involved.
That is however, until Niko began suspecting the Null Process' hidden agenda as he had been noticing the drones using special weapons against him. It all came to light as the JL-Sisters appeared, prototype androids made by Vesta who got somehow stolen by the Null Process. Their immense strength and tactics required help from Niko's friends to deal with.
Since then, Niko eventually opened up to his friends and let them tag along. This was proven beneficial for Niko as he had successfully defeated many NPDs together with his friends, further raising their success rate. Thanks to their help, they were able to save JL-1, 2, 3, and 4, adding them into their fold as Jenny's sisters, as well.
Since then, the JL-Sisters had been assisting Niko and Jenny as the JL-Arms, powerful special weapons that they can call upon in their fight against Null Process. Though they are living tools in nature, Niko treated them with respect as much as he did to Jenny and his father figure, Sinclair. Thanks to his interactions with everyone, Niko also began to see himself in the JL-Sisters, tools of war that desire peace, live their own lives to the fullest, and help each other through thick and thin.
When he asked the four JL-Sisters about the Null Process however, they claimed to know little about it as they actually went online much later after JL-5, 6, 7, and 8 had already been put to use for quite a long time earlier. Even so, the JL-Sisters also expressed their desire to help Niko and Jenny uncover the truth themselves, as well as to reunite the JL-Sisters once more.
The mystery deepens yet again, and the heroes must prepare for what is to come.
