THE EFFECT HAS ENDED(THEORY 1)[]
I , Janabora thinks that the ending of Doraemon cartoon was not as complex as the time paradox. As we all know that when Doraemon leaves nobita he gives him a potion/gadget and tells that the reverse of everything he says will happen. One day Takeshi(JIAN) and Suneo were bullying Nobita like always so he drank the potion and took his revenge. He then came home very sad because of leaving of Doraemon, so he said that he will never be a able to meet Doraemon again unknowingly that Doraemon will pop out of his desk due to the potion's effect .
I think the effect of potion has ended and Doraemon went back to future. This theory is completely created by me. The proof that my theory maybe correct is given below:-
1) In time paradox it is shown that Nobita works very hard to repair Doraemon but in stand bye me (i forgot which one) it is shown that Nobita is living a simple life.
2) Time paradox states that doraemon's ears have batteries but if we look at the first episode of Doraemon where it was introduced who he is and basic things we can see in his creation clip that the ears were actually decorations.
3)(MAIN POINT) We see that Doraemon is not with nobita in stand by me and this means he went somewhere..... probably the 2100s(Where he came from
