Team Eggman is a team in Sonic Heroes 2. Members are Eggman and Eggman Nega. Unlike most games, the game does not immediately feature Eggman; he is introduced about a quarter of the way through. This storyline's primary aim to obtain Chaos and Emerl (to create Chaos Emerl) and to collect all seven Chaos Emeralds (to power up Chaos Emerl).

True to form, the storyline curtails collecting the seven Chaos Emeralds- in this instance, to power Chaos Emerl.

Eggman Nega is busy pottering around Launch Base Zone. He contemplates, "What can I use to meet Sonic's match, or better, eclipse it?" Suddenly, a thought hits him. "An enmesh! I'll merge Chaos and Emerl together to make Chaos Emerl!" He immediately bolts over to Metal Sonic 3.0 and enters the following enquiries:

Where is Chaos? Angel Island
Where is Emerl? Gigalopolis
Where are the seven Chaos Emeralds?

The team immediately make their way to Angel Island; here, we see the cutscene at the beginning of Team Knuckles' storyline. After the scene fades out at the regular place, we see Team Eggman making their way up to Gigalopolis. Action stages HydroCity, Underground and Mystic Ruins North are played.

Once there, a cutscene occurs in which Eggman Nega criticizes Eggman for allowing one of his bases to adopt such a state. The team itself participate in Green Hill Zone up until the point at which the team hit Gimmick Mountain Zone.

Once Eggman Nega and Metal Sonic 3.0 arrive, they are in for a shock, seeing Eggman lodged in the entrance. They prompt work him out and bolt away from the scene, leaving Team Rose incensed. From here, the pattern of action stages and then treasure hunt takes the place of playable zones throughout this storyline. The first one, Aqua Lake Zone is done immediately.

Marble Garden Zone HydroCity Sunset Park Zone Great Turquoise Zone Team Sonic
Angel Island Hidden Palace Zone Lava Reef Zone Sandopolis After these zones, we see Team Eggman stage an attack on Casinopolis. This is a tricky boss because it is against halves of Team Knuckles and Team Dark (Knuckles, Shade, Rouge and Fang).
Hill Top Zone Mystic Ruins South Spring Yard Zone Labyrinth Scrap Brain Zone (argument with Tempest culminating in a boss fight against Team Babylon)
Star Light Zone (timed treasure hunt) Jungle Zone Troll Bridge Zone (boss) Mecha Green Hill Zone Sleeping Egg Zone

At the end of Sleeping Egg, an extended cutscene engages. Literally, it starts, skips to Launch Base and then departs. We see the Egg Carrier rising, similar to Sonic Adventure's elevation in Mystic Ruins. After this, we see an extended cutscene. Eggman, Eggman Nega and Metal Sonic 3.0 shoot the breeze for some time, in which we learn that the Egg Carrier has had a number of undesirable passageways built in that shouldn't be there; while Hot Shelter and Sky Deck are accounted for, but Sky Base, Wing Fortress and Flying Battery shouldn't be there. After this, Chaos Emerl is left to roam free; his job is to isolate those five zones and ensure nobody can access the interior by any entrance other than Hot Shelter or Sky Deck. Literally, zones Flying Battery Zone, Wing Fortress Zone and Sky Base Zone are played in order. (Note that this layout is deliberately presented in a similar way to archaic Sonic games; three acts and a boss at the end of Sky Base.) This boss consists of several different teams combating Chaos Emerl adjacently.

At the end of this, the other three members of Team Eggman walk into the control room and initiate "operation Robotropolis", in which the team transform the map areas into Robotropolis. Little do they know, however, that a miffed Chaos Emerl is exploring the exterior of the base again. Foolish Team Underground left a seventh, final Chaos Emerald in the Tornado and Chaos Emerl transforms instantly into Perfect Chaos Emerl. At the end of the cutscene, the game switches out into a scene of Chaos Emerl seemingly leaking into the underneath of the Egg Carrier and consequently it spins out, landing in the volcano. The storyline actually stops here, on a cliffhanger.
