Now here is how the Mandarin would make his cameo and MCU debut in one of the Spider-Man Homecoming Post Credit Scenes First Tony takes a drink of some of his wine from his bar in a glass cup, then the lights in the tower go flickering off and then the Mandarin appears in front of Tony over by the window, wearing a shiny black samauri like armor, and ten magic rings with one on each finger and as Tony thinks that it's Aldrich Killian, the Mandarin tells Tony that he was never Aldrich Killian and proves it by taking off his mask revealing himself to be Zhang Tong, who as the real Marvel Cinematic version of the character is also the world councilman after Yen from Captain America the Winter Soldier. Then he puts his helmet back on and uses the power of both his Ice Beam Ring and his Remaker Ring to forge an ice statue of the mad titan Thanos having Tony be warned just how powerful he is and that he is the villain that intends on claiming all 6 Infinity Stones to conquor the Universe And Finally the Mandarin tells Tony to be prepared to take on the Mad Titan that if he can take down first. then the leader of the Ten Rings himself will be ready for him in the future Marvel Cinematic films and then teleports out of the tower leaving Stark puzzled if he was telling the truth or not and then the scene ends For the character to be cast in the film Marvel is to cast one of these actors to portray the actual Mandarin in the film starting with the post credit scene and then onward through Iron Man 4 and beyond
Lee Byung Hun, Hiroyuki Sanada, Rick Yune, or Andy Lau
Now the reason why Marvel should have the real Mandarin make his cameo and debut here in Spider-Man Homecoming is so that they are promising us that they will do the actual version of the character and Iron Man 4 before announcing the film for Phase 4 and hopefully we won't have to find out the movies lined up for that phase until next year and that they are not getting our hopes again like they did 3 to 4 years ago In the meantime continue catching more news on Spider-Man Homecoming as we are yet to find out who else will turn up in the movie.
