LOL I actually believe Killian is Fin Fang Foom deep down and will shape-shift later... Scorch said "you have to pierce a person's outer shell to know their true character". The name one is given/the secret identity name doesn't make the person the "real" comic book counterpart, their true character...The alter-ego has to be an actual "part" of the psyche for that character to contain the spirit/destiny of a comic book character in this universe. Coulson said oh no they gave him a name, about Scorch...That wasn't real Scorch, he was branded as Scorch by the villains. it wasn't a part of him yet, ppl rolled their eyes at the name, although he said it was "growing" on him, he wasn't the real comic book Scorch when he died...
Rhodey subtly rejected the name he was re-branded with, even tho he made up excuses "WarmachineRoxx" is still his password, Tony thinks the Warmachine name is better, so we'll see Rhodey go back to War Machine. Raina manipulated Scorch's mind by re-branding him, she made him think of himself a new person. The villains gave Peterson his new name, it isn't one he creates for himself, they re-brand him with it..However, it becomes a part of him, like Iron Man is "a part" of Tony...He becomes the real character, he accepts and fulfills the spirit/destiny attached to the superego...A.R.M.O.R. and Scarlett Witch would know more about this...There could be something deep down in the genetic memory of "Killian the Great", a descendant of Alexander the Great...and maybe Skye...
10 rings is ancient in origin, Killian stole their name/image and some of their symbols for a purpose, created the Mandarin idea in his mind...The Dragon symbols came from Killian, and the dragon tattoo he put on himself. Everything changed when Thor's hammer fell, Norse mythology turned out to be real.
The legends of Dragons once existing on Earth in the ancient past were also true...Killian threw subtlety out the window, and started completely believing in some of the legends that the real 10 rings group held, he wanted to draw them out... Real 10 rings group has deeply held mythical beliefs, that come from Asia, Persia, India, etc. Hydra and the group who were after the staff have long-held beliefs about Norse and Greek mythology. Red Skull believed Hydras once existed. Red Skull was obsessed with mythology, and looked for objects of mythic origin everywhere, while Hitler looked for trinkets in the desert...The Zodiac Key is one object a Hydra cell that operated under the name Zodiac is after...Killian was sick of false faces already in IM3..
Skye mentions the Thor myths were kinda real, so there's no telling how many of our other myths were based on things of Alien origin...The dragons from myth were on Earth at one point in the ancient past, but only the 10 rings group knew where to find the remains of one in a certain valley in china, and Mandarin has not yet tracked it down, had to co-opt the 10 rings group for a much more sinister purpose attached to the Dragon tattoo idea, and why Killian chose that symbol. Killian felt the need to brand himself with it... People often decorate their outer space in a way that reflects the inside, Killian's brain accidentally showed us a "live feed" of the map of the universe, somewhere among those stars is where the Dragon hiding inside Killian's mind really comes from...Killian breathed fire, Rhodey was surprised, but it's because he secretly represents the Dragon, more than Mandarin...Killian/The Dragon created the Mandarin character, and controlled his mind all along, created him like in the comics, so it's not a lie that at this point it was him all along...the Mandarin name is now growing on Trevor. It'll be a while before their full destinies develop in this universe where Destiny is the Nemesis of Infinity, the cosmic entity known as Nemesis claims to have created the infinity stones..Trevor and Killian are still where Tony was in IM1. They're saying I am Mandarin in a superficial way. It will take a few movies before Mandarin is actually "a part" of one of them, and someone can claim I am the Mandarin again, like how Tony actually recognized Iron Man as a part of his mind in IM3. Trevor likes the attention, he wants to be seen like any actor would, he doesn't want to be "anonymous". His ego is the true match for Tony, who thinks "he's the best". Ppl in the prison still sometimes call him the Mandarin. The name is growing on him, not Killian...People will have to be patient to see a fully realized Mandarin with all the real rings alongside The Dragon. The Dragon inside Killian's mind has led him to this point by then...
Maybe deep down inside Skye is a shape-shifting dragon, and they never should have let her on the team. A shape-shifting relative of Killian's, who was found near where Foom crashed in this dimension..Skye said the Centipede name seems harmless enough. killian told her to use the Skye name, and helped create her character. The form of a human child she took after Shield discovered her, and her human form, is a front so the humans don't get suspicious. Her whole life she's been an alien shapeshifting dragon from space from Foom's species/Killian's family.
Could be cool/unexpected if Skye turns out to be a villain instead of a hero....
