Common faith hero

I study religious text as a hobby and when i sat down to rethink all the research that ive done i noticed something

So in christianity there is jesus who with his second coming will judge humanity, this, of course, will be in mankind's favour. In turn making him a "hero"

Almost the same applies to islam. In the Quran the prophet isa(Jesus) will descend from the heavens and warn the people that the day of judgement is to arrive, this makes isa a saviour, if not then Allah's chosen would have suffered without warning, this makes Jesus in the islamic world a hero too.

the third and most different statement have is from the Kali Yuga:

according to the myths in order for the age of disorder and decline to end, Kalki the 10th avatar of vishnu will make a "divine intervention" that will bring an end to the wickedness, thus ending the age of kali yuga and starting the new cycle called satya yuga which will restore dharma in the world. these three happenstances is what led to the creation of this theory.

I think that all 3 prophecies are referring to the same person/deity. I know the connection is thin and really the only thing thats similar between the claims is the heroic endeavour they(Jesus and kalki) share, but it caught my attention that they all happen at "end times" and not any other period of history. I called it "common faith hero" theory, what are your thoughts?
