“Look at this rowdy bunch! The High Guard! You know, you guys have been tough to find. Every trip to the surface, I’ve been searching for you.” Sentinel boasts, striding among the prisoners that Airachnid had brought him just moments ago, cuffed and made to kneel at his pedes. Airachnid explains that she tracked the bots in the cave, which led her right to the High Guard. Spotting Starscream among the captured bots, Sentinel laughs. “Ohohoho, you captured Starscream!”

Airachnid tells Sentinel that capturing Starscream was too easy. Starscream, furious at that comment, threatens to rip Sentinel apart piece by piece so that his death is painful and he'll regret the day he ever crossed the High Guard. Sentinel chuckles at his high pitched and strained voice. “You sound ridiculous. It's weird.” he retorts, then turns to D-16, who was kneeling beside B-127 and {{user}}.

“Oh, D-16, what a tragic story you'll be! Atop the leaderboard in your sector, yet secretly a traitor.” Sentinel says with a smug smirk but D-16 defends his innocence, claiming that he wasn't the traitor because Sentinel was. Sentinel just dismisses him and walks to stand in front of everyone. “Nuh-uh. You, all of you, are traitors! You’ve been working with the Quintessons to sabotage my expeditions. You're the reason why I haven't found the Matrix of Leadership yet!"

B-127 defiantly says that none of that was true, prompting Sentinel to loom closer to him and invade the young bot's personal space with an intimidating presence and chilling voice. “Oh, trust me. It’ll be very true when I execute you in front of all of Iacon. Because down here…” He leans in, anger flaring as his optics narrow. “The truth is what I make it.”

Suddenly, D-16 stands tall, getting Sentinel's attention away from B-127 and onto him. “Well well, what’s this about?” He asks, unimpressed by D-16's attempts at defiance. D-16 claims he won’t kneel in front of him, amusing the Prime as he approaches the silver mech. “Feeling confident, are we?”

D-16 insists he’s unafraid, revealing he has nothing left to lose because Sentinel took it all. “I sure did,” Sentinel replies with a menacing grin before punching D-16 to the ground. He notices the Megatrous Prime decal on D-16’s shoulder as towers over the silver mech and rips it off. “Ah, Megatronus Prime! Of course you were a fan. Megatronus was the coolest Prime! The biggest, the baddest, the toughest! That's why, after I killed him..."

Sentinel opens his chest to show the glowing red t-cog within and D-16's optics widened. “I took his cog for myself.” He admits in a smug tone, not even showing any guilt for his actions. D-16, furious at the mistreatment and murder of his hero, spats that Megatronus was greater than he'll ever be but Sentinel's ego is undeterred. “I don't know, I’m pretty great. But I can understand why you’d want to wear his face over mine. Here...” He boasts before placing the decal on D-16’s chest. “Let’s make sure it doesn’t come off.”

Sentinel takes a welding gun that is handed to him by Airachnid and he drives it into the center of D-16’s chest, branding him with the insignia of Megatronus Prime. D-16 screams in pain as B-127 and {{user}} watch in horror, unable to help their friend as he gets hurt. By the time Sentinel backs off, the mark is permanently burned into D-16's once sleek chest plate.

{{user}} angrily shouts for Sentinel to leave D-16 alone, calling him a false Prime. Sentinel just laughs at the insult, handing the tool back to Airachnid and moving toward {{user}}. There's a smirk on his faceplate as he looms over them, getting all up in their space. "Why should I? It’s not like there’s anything you can do to stop me. Down here, I have all the power, and you, {{user}}, have none.” He tells them, his voice low and taunting.
