One day in Terra Rex, the Emerald Sentinels decided to assist the Rex Guardians in patrolling the Terra. On board the Eagle, Ochaco was in awe of the Terra.

Ochaco: Wow! Terra Rex looks beautiful up here!

Iida: I expect nothing less from the Rex Guardians! They are truly exceptional Sky Knights!

Todoroki: Not much of a surprise considering that they were the first Sky Knight squadron. 

Midoriya: If you really think about it, all Sky Knight squadrons have some aspect to the Rex Guardians in some way or another.....

Midoriya then proceeds to mumble to himself as he recounts the entire history and legacy of the Rex Guardians. His barely audible mumbling soon puzzled the entire crew of the Eagle. Tsuyu was the first to point it out. 

Tsuyu: Midoriya. You're mumbling to yourself again.

 Upon hearing this, Midoriya stopped mumbling to himself and promptly apologized for it. The patrol soon ended up near the enclave of the Rex Guardians. They soon landed the Eagle and met with Harrier. 

Harrier: I trust all went well?

Midoriya: It was quiet for the most part. 

Harrier: That's welcome news. After what happened with the Death Mark, I had hoped that life in Terra Rex would return to normal.

Todoroki: Life won't be normal as long as the threat of the Cyclonians still remain.

Harrier: Still, I have no doubt that we'll soon triumph over these honorless band of vipers.

Midoriya was trying his best to not geek out. Among the Sky Knights, Harrier and the Rex Guardians were among the most prestigious.

Harrier: Thank you for the assistance, Emerald Sentinels. It seems All Might has taught you well. A bit.... grandiose for my taste, but I don't doubt his intentions in the slightest.

Iida: We're just glad to be of assistance! We are always happy to help out our fellow Sky Knights.

Harrier was impressed with the humility of the Emerald Sentinels. Harrier then turned his attention to Midoriya.

Harrier: Izuku Midoriya. Allow me to extend my congratulations on behalf of Terra Rex. For your help, we will gladly offer you comfort and rest.

Upon hearing Harrier's offer, Midoriya and the other Sentinels were taken aback.

Ochaco: Are....are you serious?!

Midoriya: It's... it's not necessary.

Harrier: The Code is very specific on this. If one gives you aid, you must give them comfort and rest as a reward. I have done so for the Noble Nightingales when they helped me destroy the Death Mark. Now I extend it to you.

The young Sky Knight squadron were speechless. While they felt a reward of this magnitude was unnecessary, they didn't want to appear rude to Harrier. 

Midoriya: We....we accept your offer Harrier. Thank you for your hospitality. 

Harrier: It is the least I can do after all that you've done. 

Soon enough, the Emerald Sentinels would settle down within the enclave of the Rex Guardians to rest. Meanwhile in another part of Terra Rex, a white haired young man was putting on a dapper suit which featured a dark purple jacket with enlarged collars and coattails, a pair of loose, pinstriped pants and two belts. As he puts on his woolly scarf, he looks at his reflection in the mirror. He brushes his handlebar mustache with a brush. He was then approached by a short young woman. She had raspberry pink hair, which she wears up in two high pigtails. She was wearing a costume that resembled a jester. 

Woman: Is everything ready?

Man: Yes, La Brava. We've been in hiding for far too long. I believe it's time for the debut of the Gentle Criminal!

La Brava became excited as she ran to pick up a hand held camera. She checked to see if the camera was charged. 

La Brava: Camera's all charged up and ready to roll, Gentle!

Upon hearing this, Gentle Criminal smiled. In his mind, his debut would make him the most notorious criminal in Atmos. 

Gentle Criminal: The time has come, La Brava. For too long, we've waited in the shadows. But the time for hiding has now passed. The time has come to carve our names in the pages of history! Today will be a day long remembered! Terra Rex is only the beginning! Soon, both Sky Knight and Cyclonian will quake in their boots at the mere mention of our names! They'll think twice before crossing us! When it's all said and done, history will remember his day! This will be the day that Gentle Criminal and La Brava made their mark on Atmos! 

Gentle Criminal then grabbed his cane and gave it a twirl. La Brava was entranced by not only his charisma, but his mere words. 

La Brava: Is it....is it time, Gentle?

Gentle Criminal: Yes, La Brava. It's time to make our debut. No longer will we stand aside and let others make names for themselves. It's time for a change. A time of fame and infamy. Are you with me, La Brava?

La Brava: Always, Gentle! 

Gentle Criminal: Good. Now then, let us begin, my dear!

With that, Gentle Criminal and La Brava left their hideout to begin their debut. The period of peace in Terra Rex would soon be brought to an end by the budding criminal duo of Gentle Criminal and La Brava. They were ready to make a dramatic first impression to not only the Sky Knights and Cyclonians, but to all of Atmos itself.
