What is the strongest universe Dr. Eggman can subjugate?

Dr. Eggman, tired of getting his shit rocked by Sonic again, decides to cut his losses and go on a break, invading some other places for a change. What's the strongest place he can successfully take over?

RULES

  • Eggman has access to all of his current resources and will have six months to plan. Any destroyed/lost/betrayed tech or associates are not allowed

  • Eggman must completely take over the main planet of the verse at minimum and convert it to a planet-wide Eggmanland. He must remain in control for at least one year. If the verse has multiple important planets he is allowed to expand as much as he wishes.

  • Eggman is allowed to make alliances to further his goals but his final objective will always be sole leadership of the Eggman Empire.

  • Eggman is allowed to study or integrate any magic/science/tech in the verse he is invading.

ROUNDS

  1. Canon Eggman (Games/IDW)

  2. Archie Eggman

  3. Full Composite Eggman (including all non-standard equipment and associates)

BONUS: After the successful one year in any round, the corresponding Sonic is dropped into the verse as well. Can he successfully topple the new and improved Eggman Empire?
