How do all the Marvel movies connect?

PHASE I:

This guy:

Turns this guy:

Into this guy:

Before the latter goes into a suicide mission and ends up on ice…

Years later, this guy (the first guy’s son):

Ends up imprisoned here:

So he comes out as this guy:

So this guy:

Sends this guy.. sorry! This chick:

To recruit him to his bad boys band, because of this guy’s last visit to earth:

Which, for now, include only these two:

Now this guy (the latter guy’s brother; “He’s adopted.”):

Is sent by this guy:

To get this:

So this guy (again):

Wakes up this guy:

And sends this chick to get the big guy:

And assembles the bad boys band for the first time to deal with him:

phase II:

Begins with this guy, as always, dealing with another crazy guy:

And this guy going on another one of his adventures:

And this guy dealing with his past in an unexpected reunion:

With his new-made friend, this guy:

While all of this is happening, these guys have created their own bad boys band and are having their own adventures, somewhere else:

Finally, this guy’s good-intentions and gone-wrong-experiments:

Brings the band together for a second time, to deal with this guy:

And while doing so, they create this guy (Second time is the charm, right Tony!):

Who turns out to be WORTHY!

And they recruit these guys (the twins):

PHASE III (Still Ongoing):

This guy’s divide-and-conquer games:

Cause a longed-for, bigtime fallout between these 2 guys:

Which brings this new guy to the fold:

Along with this guy’s son (metaphor):

Who is also this guy:

And the friend of cap’s newest friend:

All of these events are wrapped-up in an epic final battle between these two guys:

Just before we go to get a closer look on the father-son relationship of these two guys:

And this guy’s new adventure as the new king of a secret and powerful nation:

And while all of this is happening, this guy:

Picks up this lost big guy along the way:

After this guy helped him find his father:

To go and save this place (his home):

From this chick (his sister), Yes, I know, the guy has the loveliest family right?

On his way back to earth, he stumbles onto this guy, who comes to finish his plans by himself:

Which bring us to the big cross-over of the decade of both these bad-boys bands in an epic, last and bloody fight to stop him:

To be continued…

Edit: Thank you all for the upvotes and comments!
I just wanted to point out that the father-son relationship of Tony and Peter was a metaphor and I have edited it
About missing D.S., I didn't miss him, I have mentioned him helping Thor find his dad, like I mentioned Ant-Man helping Cap without mentioning his solo movie, because I didn’t want to mention movies, but the series of events that brought us to the final battle with Thanos!
You are right guys, Barton shouldn’t be missed! I have just added him!
