Major Regions

Kanto/Johto Regions - The Kanto region is the backbone of the UTR military, their focus on the Pokemon League challenge has made 70% of their population since the Kanto-Unovan war available for conscription. Kanto is the home of the Silph Corporation that funds the technology found in UTR warships. Due to their focus on military Kanto lacks as robust a culture as it's cousin region Johto, and it's former colony Alola. Current Regional Professor is Blue Oak and Professor Utsugi Elm, and Champion is Ethan 'Gold' Lash

Hoenn Region - The Hoenn Region is the home of most of the UTR Space facilities as well as its HQ and home of the Devon Corporation. Hoenn's military isn't as developed as Kanto/Johto, Galar, or Kalos but they are one of the planet's biggest Produce and Fish exporters and Cultural Hubs. Current Regional Professor is Brendan Birch, Current Champion is May Maple

Sinnoh Region - Sinnoh stands as the bastion of Earth culture, diversity, and affluence. One of the wealthiest regions on the planet due to its mining exports of gems, and other precious material. Sinnoh boasts the third strongest military of the Regions barely behind Unova. Is the home of the Champions Assembly Building. Current Professor is Xavier Rowan, current champion is Dawn Berlitz.

Unova Region - Unova shares a tense history with its neighboring regions of Kanto/Johto due to the 'Golden War' where Unova and Kanto found themselves at odds. Despite losing this war Unova boasts a military only slightly weaker than the Kanto/Johto alliance (Indigo Alliance). Unovan exports consist of Entertainment properties such as movies, and other media, as well as Gemstones. Home of the Unovan Stock Exchange Building. Current Professor Bianca Blair, current Champion Rosa Mei

Kalos Region - Kalos is widely considered a Isolationist Region choosing to operate mostly independently of other Regions. This resulted in them founding the Kalos PokeBall Company to keep from importing Silph, and Devon made PokeBall designs. Current Professor Augustine Sycamore, current Champion Callum Delacroix

Alola Region - A loose alliance of Islands that once were a Kingdom, tied together by their traditions, the Tapus, and mutual defense. A newcomer on the world stage Alola has only recently developed its Pokemon League, to that end it still depends on its former controller, Kanto, to defend it. Alola stands as the Third richest region due to its exports of fish, produce, and animal goods, alongside its Tourist industry. Current Professor Keiichi Kukui, Current Champion Selene Lupin

Galar Region - A region once strife with inner turmoil and split in three different states before uniting. Galar much like Kalos practiced isolationism until Mohammed Rose created the Macro Cosmo Corporation using his influence from his Electric Company he instituted the Galar League Tournament. Galar quickly became one of the most wealthy Regions due to its League's publicity, Galar also stands as the hardest Region to invade due to the Dynamax Phenomena unique to its region. Current Professor Sonia Magnolia, Current Champion Gloria Callahad

Organizations

Team Rocket: Team Rocket is one of the UTR's most notorious criminal organizations, once having stifling control over both Kanto and Johto, as well as branches in Unova and Alola. Team Rocket excelled in Black Market trading of stolen and rare Pokemon, money laundering, gambling houses, and brothels. They weren't completely taken down until their Leader, Sakaki Giovanni, failed in battle against Champions Red and Ethan.

Pokemon Rangers/N7: An elite task force of Trainers, typical operations for the Rangers consist of Regional Defense, Intelligence Gathering, and Counter Terrorism ops. Typical Ranger divisions can have around 200 members, a corps having 50, and Squads consisting of 10 trainers.

Ranks:

General - Overlooks all Pokemon Ranger Operations, works as a Military Advisor to the Pokemon Champion.

Lt. General - Insures that all Corps can be supplied, vehicles for transport are available, and decides which Corps are deployed where.

Corp Sergeant - Leader of a 50 man team.

Squad Leader - Leader of a 10 man team, usually chosen by the Corp Sergeant.

Religions:

Arceism - The dominant religion of Earth, focused around the teachings of the creator deity Arceus, this religion has sprouted many smaller sects.

Dragonistic - The second most dominant religion of Earth, most popular in Hoenn and Unova, that follows the belief of Dragon types being the dominant force in the universe. The patron god of this religion varies depending on its region, however most look to Rayquaza as the chief god of its pantheon.

Tapu - The traditional beliefs of Alola, the Tapus are held in extremely high regard as gods and protectors of Alola and its people.

Special Technology:

Teleportation Arrays: The teleportation grid created by the Silph Company is a widely available, if expensive, mode of transportation. Most models operate on building wide scales, being able to Teleport from one floor to the next instantaneously. Arrays however are limited in that they are only 'keyed' to each other, so an array will only get you to one location and back.

Rotom Tech - Rotom Technology was the brainchild of Professor Kukui, mixing Aether Tech with the upgrade ability of Rotom created a near perfect AI. Rotom Tech has made automated transportation, and automated warfare, much more seamless as it can react much faster than the human body, find problems and remedy them before they would be noticed, and make decisions due to its own sentience.

Ultra Spacian Tech - Due to the Ultra Necrozma event the Ultra Spacians have opened embassies on each region sharing it's technology for support in restoring their home, and open borders. U.S Technology allows for wormhole generation, meaning whole fleets could travel thousands of light-years in seconds, however the UTR haven't found a way to implement this tech in its warships as of yet.
