— Big the Cat, Sonic the Hedgehog Annual 2020

Big the Cat is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. He is an anthropomorphic cat that lives in the Mystic Ruins with his best friend Froggy.


Big is a very large and burly anthropomorphic cat. The majority of his body fur is purple with dark violet stripes. A striped pattern runs up his arms and long tail. His feet are covered in dark violet fur up to his ankles as well as the outer tips of his large, triangular ears, while his upper legs, back, and sides are covered in purple fur. White fur covers his chest, torso, muzzle, and inner ears. He also has black eyes with pale yellow sclera.

His preferred attire consists of yellow gloves, sandals, and a matching belt with a gold buckle. He usually keeps his fishing rod with him.


Big's Big Adventure

Some time after the Eggman War, Big was led by Froggy to several locations. In Vista View, Big fished in the sewer system and said hello Sonic who ran through there. He next went to Riverside and fished there while also seeing Sonic battle the Death Crab. Following this, Big was led to Barricade Town. While he carried boxes looking for Froggy in the supply depot, he denied a "request" in wanting to have a battle with Rough and Tumble. Next, in Spiral Hill Village, Big took note of the Badnik invasion and called for Froggy. Somewhere outside of Windmill Village, Big lost track of Froggy. The cat managed to find his way to the Egg Fleet in the sky but did not find him. He also looked in one of Dr. Eggman's pyramid bases but had no luck there either. While backtracking through Barricade Town, he saw Rough and Tumble being broken out of jail by what he believed to be a magician. He moved and believed he saw Froggy inside a battleship, only to discover that it was only a Wisp. He nonetheless took a nap in the shuttle as it flew to Angel Island. Sometime after landing, Neo Metal Sonic used the Master Emerald to become Master Overlord, causing the island to fall. This subsequently made Big fall off of the island into the ocean but he was able to stay afloat with his life preserver.[1]

About a week later, Big walked through Windmill Village again and saw Sonic fight Rough and Tumble. The cat journeyed through Frozen Peak and saw the "magician" performing his usual trick for Sonic and Silver, but found this boring. Later on, Big checked for Froggy in Echo Mine. Although he did not find him, he thought he heard the voices of Rough and Tumble. After checking all over the area, including the refuse pit, Big did not find them either and left. Big began worry about not finding Froggy. After walking through a thrashed Seaside City, he began to feel that the world was getting spooky. He soon thought that Froggy had gone to play with Cream in Floral Forest Village but found no one home. Big thus tried to find his other friends but could not find anyone. As he fished underneath the bridge in Sunset City, he took no notice of the Zombots that fell off of it after being rammed off the bridge by Shadow in a truck. Later hearing that Amy was apparently gathering everyone for a sleepover, Big made his way to Restoration HQ. When he tried to cut in front of the people getting scanned for infection, Big was stopped by Gemerl and sent to the back of the line, despite him not being sick. Big tried calling for Froggy but did not find him and left the premises early. The cat went to a hill and looked to the stars, finding himself to be lonely and a little afraid. Knowing that Froggy was likely to be lonely and afraid as well, Big decided to keep looking.[1]

Finally, Big went to a place not far from Spiral Hill Village where he finally found Froggy by fishing for him. On their journey home together, they were surrounded by a group of Zombots, who attempted to infect them. Big faced the Zombots with his Fishing Rod. A little while into the battle, Froggy jumped on a Zombot, which made the cat think he wanted to help him. After Big tied the Zombots up, the duo managed to escape they and fled back to their home in the Mystic Ruins. Big was happy to be home after a long adventure and recounted it back to Froggy. Unfortunately for him, as Froggy had previously made contact with the Metal Virus, he transformed into a Zombot, and infected not only Big but the Mystic Ruins' flora.[1]

All or Nothing

Amy hugs Big, from Sonic the Hedgehog #29.

After the Deadly Six had taken over Eggman's plans, Zavok used his powers to lead a large horde of Zombots to Angel Island, which included Big.[2] After the Faceship was effectively destroyed by Rouge, Zavok grew to a giant size to attack the survivors on Angel Island. From this, he grabbed a handful of Zombots, including Big, and threw them onto the island's surface to face the survivors there.[3] Big lurked toward Dr. Eggman until he received a hit from Amy with her hammer. However, this did not have much of an effect Big. Eggman then proceeded to kick Amy into Big so that she could get infected and he could make a quick getaway. Eventually, with the combined efforts of Super Sonic and Super Silver, they were able to warp the entirety of the Metal Virus away from the world and to the sun. This act turned Big back to normal, prompting Amy to hug him in joy. Big accepted the hug but was not aware of what had just transpired.[4]

Out of the Blue

Big reunited with Froggy on Angel Island. He soon saw Eggman flying off in the Restoration's Rescue Shuttle and pointed this out to Amy, Tails and Knuckles. Seeing that Froggy had jumped out of his hands, Big chased after him.[5] Some time later, Big was invited by Tangle to a party in Spiral Hill Village. There, he fished in the fountain. Suddenly, the group was alerted to a large crash in the town, revealed to be Eggman in a large mecha.[6] However, Big quickly forgot about Eggman's attack on Spiral Hill Village upon noticing that Froggy was gone, prompting him to begin looking for him again.[7]

Trial by Fire

Eventually, Big traveled to Forest Ridge Zone Campground, where he would fish in the nearby river.[8]


Big is a simple cat whose basic needs are limited to rest and fishing. He rarely leaves his house to avoid exposing himself to the dangers lurking in the outside world. Big is not very smart, and important things often go through his nose. This does not mean that Big is stupid but that he processes the facts more slowly. Sometimes, he also misinterprets things and is not aware of the threats that surround him.[1]

Big is very concerned when his friend Froggy goes missing and cannot focus on anything other than finding him. However, this is also a positive characteristic of him, since he shows his great determination and care for friends.[1]

Powers and abilities

Big fending off several Zombots, from Sonic the Hedgehog Annual 2020.

Big possesses superhuman strength, being able to lift heavy crates with ease or blow opponents away with a single strike from his Fishing Rod. Big also has enhanced durability and is not easily toppled by strong attacks from others. For example, as a Zombot, Big was struck by Amy's hammer but this had little effect on him. Though Zombots have high durability, they have been known to be at least knocked backward by such hits from Amy's hammer, much unlike Big.[1][4]


Big uses a Fishing Rod to participate in his fishing activities. Due to the durability of the Fishing Rod, Big can use it as a melee weapon for crushing blows. He can also use it to tie up his enemies. Big also has a lifebuoy that allows him to float on water.[1]



Froggy is Big's best friend. They both like to hang out in the Mystic Ruins. When Froggy goes missing or runs away, Big begins to search for him with steadfast determination all over the world if he has to, taking a look wherever he can and double-checking to make sure he was right. He also worries about Froggy and is ready to protect him from any threats.[1]
