In your Befriending Ben 10 Aliens AU, what if unfortunately the species you named so far got captured by the Forever Knights?
Locked up and set to be experimented on or executed, how would they react to see there human friend suddenly appearing dressed as a Knight to infiltrate the base and break them out?
Not all of them but some I thought would be interesting.
Geochelone Aerios - They never really understood just how much in danger they were. But still, they are very, very grateful that you saved them. They think you are a hero and admires how you got into the Forever Knight's base without any needless violence. From now on, when they talk about you with someone else, they refer to you as "Y/N the Hero".
Splixson - Breaks out in tears. Loud, ugly crying. They are so happy to see you, you can't even imagine! Immediately splits and all the copies hugs you, creating one big, emotional group hug. You have to calm them down before the two of you sneak your way out of the Forever Knight's base. The Splixson will be extra clingy for a while after.
Tetramand - They feel a bit embarrassed and ashamed that they got caught in the first place and that they had to be rescued. Still, they really appreciate that you came for them, that you put yourself in danger for their sake. Congrats, if you were friends before you are uber-best friends now. That's your loyal companion, your left hand(s). Since you saved their life, they kinda see you as the boss now, the leader of the friend group.
Petrosapien - As someone that's always kinda seen themself as YOUR protector, the sudden flip in dynamics kinda confuses them. But they won't complain. No, if anything, they are even more protective of you now that you've saved them. Because surely the Forever Knights aren't happy with you now and will come for you. Don't worry, your Petrosapien friend won't be caught off guard a second time and this time, they will repay the favor!
