Hal Jordan became a Green Lantern when Abin Sur, a dying Green Lantern, crash - landed on Earth. His ring chose Hal as its new wielder because Hal was fearless. Hal was a test pilot, which also showed his courage and ability to face danger.
I'm not sure specifically as it could vary greatly. Fanfics are often based on existing stories or characters, so it might be about a character with some sort of power and the events that unfold around that power. Maybe it's a warning to others about the might of a particular character in the fanfic's universe.
One of the best Hal Jordan stories is 'Emerald Twilight'. It shows a dark turn in Hal's life as he succumbs to the power of Parallax. Another great one is 'Rebirth' which rejuvenates his character and brings back his heroic essence. Also, 'Secret Origin' is a classic that delves into his origin story in an engaging way.
I really don't know the main characters in 'beware my power fanfic'. It could be that the main character is the one who possesses the power that others need to beware of. Or perhaps there are multiple main characters, like a group of friends or allies who are either trying to control or oppose the character with the power.
Hal Jordan's origin story begins as a test pilot. He was chosen by a dying alien named Abin Sur to inherit his power ring, which made him a Green Lantern. This ring gives him the ability to create constructs out of green energy, limited only by his willpower.
Sure. 'Green Lantern: Secret Origin' is a great one. It tells how Hal got the ring and became a Green Lantern. Another is 'Emerald Knights' which is a collection of stories about different Green Lanterns, with Hal being a central figure in some of them. And 'Green Lantern: No Fear' is also worth reading as it shows Hal's early adventures as a Green Lantern.
Well, it's a crucial part. It kind of mended the broken parts of the Green Lantern narrative. It cleared up a lot of the convoluted plotlines that had developed over time. And it was a way to get fans excited about the Green Lantern again. By focusing on the rebirth of Hal Jordan and his connection to the power of the Green Lantern, it re - established the core of what makes the Green Lantern stories so great. Plus, the art in the graphic novel was really cool and helped bring the new and old elements of the story to life.
It depends on your taste. Some people love the imaginative universe and complex plots of Green Lantern comics. However, if you're not into superhero or sci-fi themes, you might not find them as good.
