Loki has also gone out of the way to show us Kang several times now. Kang the Conquerer is set to be the MCU's next Thanos, although I doubt he will die as quickly (if at all). Kang may be an ongoing menace in the sense of the Joker...he just doesn't go away. Jonathan Majors is set to play Kang in Ant-Man: Quantumania; however, I'm 100 percent sure he'll pop up in person before then.
Kang is shown in the center of the Time-Keepers almost every time they are shown. When Miss Minutes explains the TVA to Loki in Episode 1, Kang is front and center. Also, in Episode 2, we see a long solo shot of Kang's statue in Ravonna's office. Fun fact: Ravonna is also Kang's love interest.
Loki spending so much time setting up the idea of timelines, the multiverse, breaking the multiverse, and nexus events all while shoving Kang in our faces is just the biggest tease for fans. I will be shocked if Kang, in some form, doesn't show up in person soon.
Let's also not forget that Kang is Nathaniel Richards, an alternate universe descendant of the famed Reed Richards (although some records claim he may also descend from Dr. Doom). This means Fantastic Four ties are already being laid down, and it's interesting to see that Richards is Black. Will this affect how Reed Richards or Dr. Doom are cast? Possibly. Kang travels back and forth within his own history so much and spawns so many variants that we should assume the Kang in the MCU is Prime Kang. I'm sure we'll see variant Kangs as time progresses.
