Ant-Man Quantumania Post-Credit Scene. Here are the full descriptions of the two scenes. SPOILER ALERT!
Once again before I start, I just want to remind you that this discussion will cover two credit scenes from Ant-Man and the Wasp: Quantumania (2023). So for those of you who may not have seen the movie, be warned!
Ant-Man Quantumania Post-Credit Scene

Okay before we get into the explanation, let’s briefly review the descriptions of the two credit scenes.
The mid-credit or first scene features 3 variants of Kang the Conqueror (Jonathan Majors). Then at the end of the scene we see many variants of Kang sitting in a large hall.
The second scene features Loki (Tom Hiddleston) and Morbius M. Mobius (Owen Wilson) looking at another Kang variant.
Reminder

One more thing I want to say before we finally review the explanation of the two scenes. So the explanation that you are about to read is 100% speculation or guesswork. Then all of this speculation is also 100% from my point of view. So it is not certain that what is explained here is completely valid.
Meaning of the First Credit Scene

This scene features 3 variants of Kang. According to GQ, the three variants are: Rama-Tut, Immortus, and Scarlet Centurion. Now these three are very likely to be 3 officials from the Council of Kangs.
The Council of Kangs is a collection of Kang variants sitting in this large hall that we see towards the end of the credits. In the comics, the Council of Kangs was formed to prevent or end the chaos created by various versions/variants of Kang across the multiverse.

Now in the credit scene, the 3 high-ranking officers discuss the death of Kang, who is the main villain in Ant-Man and the Wasp: Quantumania. After talking about it, Immortus said that he is getting really worried about all the main earth (Earth-616) MCU superheroes.
Their concern is for most of the earth’s superheroes who now know and are interested in the existence of the multiverse. After that, Immortus then invited Rama-Tut and Scarlet Centurion to start moving to stop all the heroes on Earth-616.
Meaning of the Second Credit Scene

In the second credit scene, we see Loki and Morbius in a large hall as well. But this hall is more like a large theater room. Now there the two of them met with Kang’s variant, Victor Timely. Timely in his scene is explaining an innovation or important thing.
When he saw his figure, Morbius was very impressed with Victor. As a result, it is not surprising that Morbius then asked curious questions when he found out that Loki actually considered him a scary figure. Loki also answered that Victor was indeed a scary and dangerous figure.
Loki Will Stop All Kang Variants

Well this credit scene is clearly one of the scenes that we will later see in the Loki Season 2 series. Through this scene, we can confirm that in this second season, Loki has a mission to stop all variants of Kang.
But to be sure, let’s wait until the second season of Loki airs in mid-2023. Now that’s a brief explanation of Ant-Man: Quantumania Post-Credit Scene. Hopefully the explanation is useful.
