A Marvel Comics limited series stands out because it offers a focused and self-contained narrative. It can explore new concepts or provide in-depth looks at familiar characters without the long-term commitment of an ongoing series. Also, the art and writing might be more experimental or targeted to a niche audience.
The thing that makes a Marvel Comics limited series stand out is its ability to tell a complete and compelling story within a defined number of issues. It allows for more creative risks and can delve into less mainstream storylines that might not work in an ongoing series. The limited format also creates a sense of urgency and collectibility for fans.
