The alien may be from the future but he has been in that time line long enough and invaded earth with the rest of the aliens so he can still tell them why they invaded earth they only did it because they want info about humans and if they do they will take over the earth if they take over earth that will be the end of the human race *this chapter is based off fake events so please do not hate this chapter thank you* but because of the green arrow ,super girl , atom, the white cannery the earth is safe.
