General
Monopole is shown to be a very advanced high-tech city area and has tube-like roads with hover-cars, colossal and awe inspiring building structures and robot-workers walking on the streets, making it resemble something taken directly out of the future.

In line with its imposing stature, Monopole features a large variaty of areas, such as the bustling and prosperous metropolis of Megalo Station, chrome canals which resembles the canals of Venice and ecospheres containing an abondance of flora.

Monopole is also known for housing the headquarters of MeteoTech, a security manufacturing company which is owned by Dr. Eggman. As shown in Sonic Riders: Zero Gravity however, this company is merely front for Eggman's Eggmanland project; by using the city's dependency on technology, Eggman planed to infiltrate Monopole's society with his SCR-GP security robots and then use them to take control over the city and possibly the world. His plans however became endangered when the Arks of the Cosmos caused his robots to run amok on their own and was ultimately foiled by Sonic, Tails, Knuckles, and the Babylon Rogues.
