History:
(Mighty Thor III#22) - When the War Thor ventured into Muspelheim to battle Sindr, Queen of Cinders, Sindr tossed the War Thor into a lake of lava, drawing the attention of the Fire-Breathing Sharks residing there. Muspelheim goblins soon asked Sindr where the War Thor was so they could lay his gizzard at her feet but Sindr suggested they let the Fire-Breathing Sharks have their fun. As Sindr mused over Thor becoming more of a problem despite the dark elf Malekith's insistence that he was handling Thor, the War Thor appeared wielding a Fire-Breathing Shark as a weapon and slammed it down on top of Sindr.

(War of the Realms I#1 - BTS) - As the War of the Realms began, Loki appeared and defended Freyja, prompting Malekith to remark that he had seen swamp dragons and firesharks and a sea of squirming maggots but never a Loki that defended mothers.

(War of the Realms I#3 (fb) - BTS) - When Asgardian creatures invaded Earth during the progression of the War of the Realms, Muspelheim's Fire-Breathing Sharks appeared on Earth as well.

(War of the Realms Strikeforce: The War Avengers#1) - A group of Fire-Breathing Sharks and Muspelheim goblins chased Deadpool, who unloaded bullet after bullet into the Fire-Breathing Sharks to no avail. The Sharks and goblins eventually chased Deadpool into the Pacific Ocean, where Deadpool hoped the water would douse the Sharks' fire. Unfortunately, the water doused nothing and one of the Fire-Breathing Sharks devoured Deadpool.

(War of the Realms I#3) - Namor the Sub-Mariner battled the Fire-Breathing Sharks in underwater Atlantis.

(War of the Realms Strikeforce: The War Avengers#1) - A short time later, after Namor the Sub-Mariner killed that particular Shark, he found the still-living Deadpool inside the Shark and he demanded Deadpool explain himself. Deadpool revealed how Malekith had started a War of the Realms and invaded Earth, prompting Namor to ask why Deadpool had brought the Fire-Breathing Sharks and Malekith's war to Atlantis. As the two looked out over Atlantis, where more Fire-Breathing Sharks and Muspelheim goblins were battling Namor's Defenders of the Deep, Deadpool admitted that he had hoped the water would have doused the fiery Sharks. When Captain Marvel and Sif of Asgard made their way to Namor, who argued about Deadpool bringing the Sharks to Atlantis, Sif commended Deadpool on bringing the Sharks into water, as lowering their body temperature made their easier to kill.

(Avengers VII#21 (fb) - BTS) - In the aftermath of the War of the Realms, the waters around Avengers Mountain became teeming with the remaining Muspelheim firesharks, leading Captain Marvel to suspect Namor had dumped them there.

(Avengers VII#21) - Captain Marvel took Ghost Rider out in Tony Stark's speedboat to help round up some of the firesharks via fishing while the two discussed Ghost Rider's anxieties with the superhero life.
