Begining

Alador was the child of two retired SHUSH agents, so when FOWL came back onto the scene he and his family instantly became key targets to their plans. Alador especially as it had his parents intelligence and skills, he could also be tricked easier then trained SHUSH agents – even if they are now retired.
He has remained in their custody for years now, for simplier experiments after it was clear he wouldn't join them voluntarily. His stubbornness really didn't help this matter either, often getting on their nevers

Plant Life

After Taurus Bulba brought the Fearsome Four into their world temporarily this set a plan forward for FOWL to use in regards to Alador – fascinated by the abilities Bushroot showed they tried to recreate him themselves. They were successful – though not to the same depth as Bushroot - none of them had spent years specialising in plant science after all and it ended in a more partial transformation. The plants not completely taking over and replacing his original body, but he still had a few bonuses. The ability to control and communicate with the plant life aroundhim, some of his own body parts being replaced, providing it with extra strength and the ability to regrow when injured. It even gained the ability to photosynthesis and survive just from sun and water - though this could not sustain him solely, still needing to eat and drink normally every few weeks. FOWL really pushed how far he could survive this, only feeding him again after a month passed and it became very clear that he was weakening and becoming sickly without normal food.

Escape

After his escape he wasn’t too sure what to do at first, ostracised by those he used to know in St. Canard. He even went to his parents desperate for help and hoping they would understand, at the core of it them being his parents was the issue, what caused FOWL to take him and do this, but they didn’t. Horrified by what had become of their son, and convinced that he was no longer the one in control, that FOWL must have removed everything that was their son. This broke his heart and was the final nail that he couldn't be who it once was. No one would understand him, even those who said they’d be by his side forever and always.
So he turned to crime for a while. Nothing major, he didn’t want to hurt anyone and it still wasn’t used to the powers they now had – so they did occasionally hurt people and this hurt it in return. Moss did not want to hurt people, but sometimes the plants listened to his emotions more than his actual commands, lashing out using his hurt at what he now was.
