Trouble in Paris
Big and Froggy found themselves in Paris fishing in the river. Big asked Froggy not to eat anymore sparkly stones, because he didn't want to see Chaos or another tail on Froggy, when they were interrupted by fireworks. They watched the fireworks spell out "Happy Birthday Chris" and walked towards them to see where they were coming from. As Big remembered the fireworks, he is alerted by Froggy over to a disguised Dr. Eggman with Decoe, Bocoe and Bokkun. Big agreed with Froggy that he looked like Eggman, but ignored his suspicions as Nelson and Lindsay Thorndyke were unveling the new space shuttle. Big watched as the space shuttle was shown to the crowd and Eggman unleashed various robots to attack the crowd for a distraction. Sonic, Tails and Amy rushed towards them as Big and Froggy overheard Eggman and realised that it was truly him. Big intervened as Eggman boasted about his plan of stealing the space shuttle. Eggman ran away after noticing Big, but is grabbed by his fishing rod and pulled back. Big told him that he won't let him steal anything and stopped him by punching him in his nose, and knocking off his disguise. With his disguise exposed, Big and Froggy followed Eggman into the hall of mirrors with Tails, Amy, Rouge, Topaz and Eggman's robots. He was further joined by Sonic, Chris and Mr. Tanaka as they searched for Eggman in the building. (SX: #8) As they searched, another robot designed as a spider smashed through the building, and Big used his fishing rod to save Froggy from being crushed. With all of them trapped underground in the sewers being forced under by rubble, Big and Froggy introduced themselves to Rouge, Topaz, Chris and Mr. Tanaka. Sonic, Tails and Amy eventually came to their rescue, but none of them were able to lift Big and Froggy out of the sewers by themselves. Tails, Amy and Rouge tried to lift him, but were unable to until Froggy jumped off him and they were able to lift Big easily. Tails, Amy and Rouge rushed to stop the robot while Big freed Froggy using his fishing rod. He managed to save Froggy as the defeated robot smashed through the remains of the hall of mirrors and joined the reunion with the cast after Eggman fled. (SX: #9)
Big would later travel back to Station Square and joined Sonic and his friends for a barbeque. He spent most of the time fishing in the swimming pool, until Chuck directed them to his telescope. He heard Chuck telling them that a meteorite with a Chaos Emerald inside would hit the South Pole. Chris decided to make it a competition that they would race to bring back to the Chaos Emerald; to which Big was picked to be on Sonic's team with him and Tails. Big and Froggy followed their team to the South Pole to grab the Chaos Emerald within the meteortie and worked with Sonic and Tails to grab it. He helped the team by attempting to fish out the meteorite and tripping Vector over his fishing line. His team arrived back first with the help of Sonic, but were unable to find the emerald in the meteorite. Chris arrived last with Charmy and Cream and had retrieved the Chaos Emerald, and thus winning the competition. (SX: #33)
Big stayed in Station Square with Froggy as Shadow from the Prime Zone arrived. He was fishing on the coastline as Sonic and Shadow confronted Eggman and Metal Sonic, where Shadow would use Chaos Control and leave with Metal Sonic. (SX: #40)
Big shares his Prime Zone counterparts abilities in fishing and strength.
Big has the same characteristics as his Prime Zone counterpart, being a laid back, somewhat simple minded lover of life who takes things in his stride.
