Even before "Loki" aired its first episode, Kang was already a strong possibility for being the show's villain. The show deals with time travel; Kang is a time traveler. The cast includes Gugu Mbatha-Raw as Ravonna Renslayer; Kang falls in love with a princess with that name in the 41st century. Since "Loki" started airing, the Kang rumors have only grown more intense. This was especially true in the show's fourth episode "The Nexus Event," when it is revealed that the Timekeepers (the supposed rulers of the TVA) are fake. More importantly, one of the fake Timekeepers bears a resemblance to Kang.
However, it wasn't until "Loki" episode five "Journey Into Mystery" where it started to feel like Kang must at least make a cameo. There are two Kang connections from that episode which you may have missed. As Loki (Tom Hiddleston) and his variant contemporaries set across the wasteland of the Void at the end of time, they encounter a destroyed version of New York City. Among the rubble is what appears to Avengers Tower, except there's a different name on it: Qeng. During the All-New, All Different Avengers run at Marvel Comics, Avengers Tower does take on new ownership in the form of Qeng Industries CEO, Mr. Gryphon.
"Loki" is all about variant versions of people from a "sacred timeline" — fitting given that Mr. Gryphon turns out to be one of several variant versions of Kang. So not only does the name "Qeng" have a direct comics correlation, but even the stories have a variant theme in common.
