Eggman: The Video Game – Part 2: The End of the World is episode 52 of Season 2 of Sonic Boom, the CGI comedy series made by Technicolor Animation Productions with Sega of America. It premiered in the United States on 11 November 2017 on Boomerang, closing the series.
Synopsis

Sonic talks his way out of the finishing blow, and as the rematch rages Eggman flies home with his footage, so he misses Sonic and Shadow working out that the trash talk was a fake. Shadow comes for the doctor, Orbot and Cubot are reduced to talking heads, and Eggman flees to Mombot’s house with a desperate plan: let another Eggman take the fall.
Using Morpho’s portal device, he swaps places with Lord Eggman, who heads straight for Sonic, laser sword drawn. Shadow and Sonic end up in the other world facing a Metal Sonic upgraded with the stolen game data, and the battle spills back home, where the whole team pins the robot down until Sticks’ staff takes it offline.
Then Shadow reveals the real threat. Both Eggmen are now his prisoners, stashed side by side, and since two versions of one person can’t share a dimension for long, the universe is doomed. As storms gather, Tails repairs Metal Sonic, whose homing beacon leads Sonic to the bound doctors, and one kick sends Lord Eggman home just in time. Shadow vows a rematch. Lightning has wiped Eggman’s precious footage, but he isn’t worried: “Well, there’s always next season.”

Trivia
- The final episode of Sonic Boom. There was no next season.
- Shadow, Metal Sonic and Lord Eggman all return for the finale, which also brings back Morpho and Mombot.
- On DVD in the US: NCircle’s Season Two, Volume Two (September 2021), The Complete Season 2 (2021) and The Complete Series Blu-ray (2022).
- Sources disagree on the US premiere: we use 11 Nov 2017, back to back with Part 1 (Luke, Sonic Retro, Sonic Wiki Zone, Toonzone schedule, Showbuzz Daily ratings); 18 Nov 2017 (Wikipedia list, uncited) gives a different date.
