Okay, after some time of deciding. I've finally decided to do a green lantern frozen crossover. It's where a year after the great thaw, Elsa has overcome all her fears, and receives a green ring. Also, in the city of Chicago, a character of my own, he's strong with hope, and the blue lanterns send him a ring.
In outer space, 2 months after Razer had left to find Aya, the Green Lantern's Hal Jordan, Kilowog, and Sinestro were heading to the Blue Lantern planet Odym, escorted by the guardians Appa and Sayd.
When they reached the planet, Ganthet was standing in front of the blue power battery, waiting for them.
"Welcome, my friends. You're just in time," Ganthet welcomed.
"In time for what?" Hal asked.
"The time has come. I finally have enough energy to light the blue power battery once again."
"What good is this hope, anyway?" Appa asked.
"You'll see. Once the battery is lit, it will supercharge mine, Jordan's, and Sinestro's power. Go ahead, Ganthet light the battery," Kilowog said.
Ganthet then went up to the battery and spoke, "In fearful day, in raging night, with strong hearts full our souls ignite. When all seems lost in the war of light, look to the stars, for hope burns bright."
After he spoke the oath, the blue battery released its blue energy of hope, which supercharged Hal, Kilowog, and Sinestro.
"I missed being as powerful as this. It's good to have it back," Kilowog laughed.
"Impressive," was all Appa said.
"I've never felt a power this strong before," Sinestro said.
"You'll learn to love it," Kilowog said.
"Now that the battery has been lit once again, I can now send out more blue rings. Before Razer left, I had enough power to send him one. But now I can send many more, for now I'll send 800," Ganthet said, sending out hundreds of blue rings.
"Come, Sayd. We must return to Oa," Appa ordered.
"You go. I'm going to stay a little while," Sayd replied.
"Suit yourself," Appa said, teleporting away.
"Hey, I thought you gave up those powers," Hal said.
"We did. But the guardians had a bad feeling things were going to go bad, and we decided we'd need them again," Sayd replied.
On Oa, Appa was talking with the other guardians and they decided, they'd send out 1000 Green Lantern rings.
Once they sent them out, one of the rings went to Earth, and it knew just who it wanted. As the green ring went to Earth, a blue one followed in search of finding someone full of hope.
In Arendelle Norway, one year after the Great Thaw, Elsa and Anna had gotten along better each day since that day. It was a warm summer night, Elsa and Anna were in Elsa's room talking, when a bright green light appeared at the window.
Elsa went and opened the window, and the little green thing floated down to her, which she caught in the palm of her hand.
"A ring?" Elsa said, confused. "Where'd this come from?"
Just then, the ring created a giant green sphere around Elsa, then it flew through the window and up into space.
"Elsa!" Anna yelled, seeing her sister disappear into the night.
In a city in Chicago, a young man at the age of 22, who had short slicked up black hair, pure blue eyes, light tan skin, and wore a white leather jacket lived in a small apartment in the city, and he was full of hopes every day of his life.
At night, he was in his small apartment watching TV, and all of a sudden, a bright blue light filled the entire living room. He looked to see a something small and blue floating down towards him. When it was close he grabbed it with his thumb and forefinger with his right hand.
"What kind of weird looking ring is this?"
The ring then started to glow, surrounding him in blue light Then in a bright flash, it teleported him out of his apartment.
Ok, that's the prologue. Next chapter this guy and Elsa arrive to the Lantern's planets, where they begin to learn about Lantern Corps. This guy of mine, he'll befriend Sinestro, until he becomes a yellow. It's something I've been thinking up for months. And the story explains as it goes along.
