Kang's 18147 Bridge Code In Quantumania Hides Deep-Cut Ant-Man Easter Eggs
During the final act of "Quantumania," while Jentorra (Katy O'Brian) and her rebel faction are storming Kang's citadel, they reach an impasse (literally) when one of the bridges is retracted. The telepathic rebel Quaz (William Jackson Harper) is quickly able to read a nearby soldier's mind and extract the code: 18147.
This number might seem innocuous to many viewers, but it actually holds two different references to the "Ant-Man" comics, as pointed out by Redditor u/Rosililly27. The first part of the code, 181, is a reference to "Avengers" #181 — the issue in which Scott Lang first appears. The second part of the code, 47, references the issue in which Scott took on the actual mantle of Ant-Man: "Marvel Premiere" #47. Both issues were published in the spring of 1979, about a month apart. Scott has been a key piece of the Marvel universe ever since.
The Easter egg is certainly easy to miss, as the whole bridge scene flies by in just a few seconds. Conceptually, it's nice to reference Scott's origins in the third installment of his journey. Unfortunately, "Quantumania" doesn't seem committed to moving forward Scott's narrative in any meaningful way.
