After signing his soul over to Black Hat, Flug was given three rules to follow. Rule one, obey Black Hat, a rule he knew he would have to follow when he decided to work for him. Rule two, never reveal his identity to anyone, he is more than happy to follow that rule even if it means he has to wear goggles and paper bag 24/7. And last but not least, rule three, when Black Hat calls him Flug he is to be completely submissive and cowardly but when he's called Slys he is to act like the sadistic evil scientist that he is and when Black Hat isn't around he is free to act however he wants.
Black Hat loves having someone cowering in fear because of him, even if it is an act, which is one of the reasons why he rarely calls for Slys and also to fool everyone into thinking that his scientist is truly afraid of him and is forced into this job on the off chance that someone finds out who he is.
Flug knows and understands the usefulness of being underestimated, even if he would like to be feared for the villain that he is, so he had no problem saving his sadistic side for his test subjects, after all, the chances of them escaping is zero per cent so why should he hold himself back? He personally designed and overlooked the construction of his secret lab, the one that not even Black Hat is allowed in. There are no windows, no cameras and a classified amount of robots keeping anyone other than him from getting in or out.
Demencia and 505 have never seen him as Slys before, he has always done his best to be a kind and gently parent to 505 and while Demencia does enjoy angering him for fun he never thought she deserves to be on the receiving end of his dark side. The people on the receiving end of his dark side...well it never ends well for any of them.
He loves his new life, which might be a surprise with how stressful the job can be with Black Hat as his boss but he truly loves his life and won't change it for the world. Too bad the betrayal of one very stupid client would change his life, for better or for worse has yet to be seen.
~Black Hat Manor, Flug's secret lab~
"You won't get away with this!" The hero curled up in the corner of the cell hissed. He was just injected with one of Flug's new poison and had run away with his tail between his legs when the Hatbot-Sentine let go of him.
Flug rolls his eyes. "Yes yes, I won't get away with this, I'll regret doing this, do you really think you're the first to say that to me?" He raises his eyebrow as he watches the hero, the poison is slow working so it will take a while before the symptoms will appear. He hands the clipboard and pen to the Hatbot-ler standing at his side before turning around to leave only to stop in his step when he heard the hero's voice.
"Why are you working for him?" The hero yelled to get Flug's attention. "You could use your intelligence to help people! If you need help getting away from Black Hat just let me go and I'll help you get away from him!" He did his best to keep his fear from his voice but Flug can still hear it and it made him grin widely under his paper bag.
"Re-really?" Flug asked with hope in his voice as he turns around to face the hero. "You...you can get me out of here?" He widens his eyes to make himself look more innocent than he is even though it is hard to see because of his goggles and wrap his hand around his arm to seem vulnerable.
The hero allows himself to relax, having fallen for Flug's trick. "Of course! With your help, we'll be at the Hero's headquarters before he even knows we're gone." He smiled softly to reassure Flug.
Flug struggling to keep himself from laughing, he really can't believe how easy it is to trick the hero into letting his guard down. "But what about 505 and Demencia?" He asked once he is sure he won't bust out laughing. "I can't just leave them...Demencia would never leave Black Hat..." He can see the hero taking in the information he has given him, probably thinking he can use it for later, not knowing he would never be leaving.
"We can come back for them. Once we rounded up as many heroes as we can find we'll come back for both of them." The hero promised, sweat beginning to form on his forehead and Flug knows it isn't because of their conversation of the conditions of the cell.
"But...where would we go?" He asked softly, he can hear the Hatbot-ler writing everything down. "Who would want us? We have nothing out there, we depend on Black Hat for everything..." He said in a weak voice as he looks down, suddenly finding his feet more interesting than their conversion.
The hero looks at Flug with pity in his eyes, believing that he didn't work for Black Hat because he has chosen to. "You can work for us and we'll help you start a new life. We can always use someone as smart a-" He was cut off as Flug laughed.
Flug really couldn't hold it in anymore, heroes helping a villain? Thinking that intelligence is useful? Wow, it must really be a long time since he was around heroes if they really think that way now.
The hero is taken aback by the laughter but it didn't take long for him to narrow his eyes and be on his guard again. "What's so funny?" He hissed, knowing that he had been tricked.
"Oh, it's nothing really." He grinned as he straightens himself, taking a more confident standing position as he claps his hands together. "You're smart, you can work for us and we'll help you." He said mockingly before laughing again. "Do you really think Black Hat was my first choice? That I grew up thinking that I want him as my employer?" He tilts his head as he moves his hands behind his back. "I've tried, you know. No heroes cared how smart I am, how useful I could be to them, all because they only want people with superpowers. You can't be a hero or help the heroes if you don't have any powers."
Granted he was only 10 when he gave up trying to show his family how useful he can be but still! He was only 2 years older when he met Black Hat and he immediately praised and accepted his genius method of finding him and even offered him a place in his school. Black Hat is the first person to recognise his genius mind and offered him a way to increase his knowledge instead of holding him back because of his age. Even now he is still encouraged to seek out any knowledge he desires as long as it doesn't get in the way the of his work, perhaps that is the reason he wants nothing more than to please his boss.
"You're lying! They are more than happy to accept smart people!" Sweat is rolling down the hero's face and he is starting to breathe a little heavier than before.
Flug shrugs his shoulders. "Believe what you want, it doesn't matter to me." He turns around to walk away. "You've already wasted enough of my time." He walked away and this time he did not stop no matter what the hero said. He heads towards his usual lab and fell to the ground before he can take a step inside because he was tackled to the ground.
"Flug! Where have you been? I've been waiting for you for soooooooooooooooo long!" Demencia, the one who tackled Flug, whined and jumped onto her feet to run over to where she had dropped her axe. "I need you to fix this right now, I have a job in an hour and I want to chop off some heads!" She grinned as she carelessly drops her axe on Flug's table.
Flug gave himself a few seconds to catch his breath once he has gotten onto his feet, being tackled to the ground is never a fun activity for him, before walking over to examine the axe. It isn't as bad as he thought, just have to replace the handle Demencia somehow bend and it shouldn't take more than 10 minutes. "Go wait outside, I'll give it back when I'm done." He said as he picked up the axe and carefully remove the handle.
"Eh? Why?" She whined as she moves to stand next to Flug and poke his cheek through the paper bag. "Can't I just wait here? It's boring outside!"
"You're not even supposed to be in my lab, Demencia. Go bother someone else." Flug rolls his eyes as he takes a step to the side to get away from Demencia, he hopes she will get the hint that he doesn't want her here but he knows he isn't that lucky.
"Hmm... Nope! I'm not leaving until I get my axe." Demencia said cheerfully with a mischievous grin on her face.
It took Flug twice as long to finish and even with her axe returned to her she still didn't leave until it is time for her to go. Flug is annoyed and angry with her but not once has he kicked her out of his lab or wish harm upon her. As long as she doesn't destroy any of his work he would never kick her out of his lab even though she isn't allowed inside it, he knows that she is just bored and wants some attention and she never destroys any of his work on purpose.
He really can't stay mad at her for long even if she did break something, only the people living in Black Hat's Manor isn't afraid to even be in the same room as her and with how busy everyone usual is it can get a little lonely for Demencia. She knows better than to disturb Black Hat so she would usually find him or 505, with him being the easiest of the two to find because he spent a lot of his time in his lab. She is there for him when he needed someone so he will be there for her as well. He will not treat his new family the same way his old family treated him.
