Zone Cops

Zone Cops are police that patrol all the zones of the multiverse from the No Zone and make sure that all the zones are on a balance and aren't over-run by other zones. The most well known Zone Cop is the counterpart to Sonic the Hedgehog, Zonic, who has recruited Sonic for various missions across the multiverse and faced incredibly powerful enemies. The Zones Cops are currently in the middle of a war with a mad man known as Dr. Nega.

Officer Zonic's Interactions with the Prime Zone
Though unnoticed by Sonic, a Zone Cop called Zonic, (his No Zone counterpart), was responsible for numerous examples of crossovers, including the Universalamander incident, a few Evil Sonic battles, and the Giant Borg incident. Sonic never noticed Zonic's presence until an encounter with Sally Moon, and Dr. Ivanna Robotina, during which, Zonic makes his presence known in order to speed up the returning of Robotina to the Luna Zone. Zonic explained that Sonic is called often because he is the Prime Zone's Sonic, and is destined to be the champion of all realities. (SSS: #8)

Giant Borg Crisis
Following this, Zone Cop officer Zonic brought Sonic to the No Zone in order to track down numerous thefts of Giant Borg parts committed by Evil Sonic, under the employ of Robo-Robotnik (though his involvement was unknown by the Zone Cops at the time). Evil Sonic accidentally gave the pieces to the wrong Robotnik, leading to a battle with the Sonic Underground version of Dr. Ivo Robotnik, where Sonic was aided by his counterpart in that Zone, while Zonic was aided by that reality's version of Sonia the Hedgehog and Manic the Hedgehog in tracking down and capturing Evil Sonic. Once the latter was captured, Zonic imprisoned him in the No Zone, where he added insult to injury by revealing that the Anti Freedom Fighters named Evil St. John as their new leader. (SSS: #10)

Missions with Other Zones
Zone Cop officer Zonic later stopped an assault from Sallactor (another version of Sally Acorn), just in time to recruit Sonic for a battle with giant monster versions of Sally, Bunnie Rabbot, Knuckles the Echidna, Tails, Rotor, and Amy Rose. After the battle, Sonic demanded to know why Zonic knew that Sonic would win the battle, and choose correctly, even if it meant killing a Zone version of his father. Eventually Zonic chose then to finally reveal his face and identity. (SSS: #12)

Zonic later rescued Sonic from another Zone where Evil Sonic framed Sonic for the crime of "Extreme Emotional Anguish and Permanent Mental Scarring" (read as insulting someone) in Ligitopolis. (SSS: #14)

One of the many realities officer Zonic explored was the possible future universe in the year 4235 and the Freedom Fighters of the Galaxy were the primary defenders. Though not interacting with the people of that universe, he watched to see how events progressed. (StH: #103, #104)

Some time later, officer Zonic was attacked by the escaping Evil Sonic. Wounded, he fled to the Prime Zone where he was found by Sonic, Antoine D'Coolette, and Antoine's father Armand D'Coolette. Sonic took Zonic to Dr. Quack for medical attention. Zonic recovered in time to warn Sonic about Evil Sonic, neither of them aware that Sonic was planning to disguise himself as a villiain so that Antoine could take him down and impress his father. By the time Zonic and Sonic arrived, Antoine had already taken down Evil Sonic, unaware that it was the real Evil Sonic. Zonic returned Evil Sonic to the No Zone. (StH: #112)

Zonic's Aid to the Chosen One
Much later, Mammoth Mogul attempted to destroy every Zone in existence. Knowing that Mogul only feared Tails, the Chosen One, Zone Cop officer Zonic recruited all of the Tails from all of the Zones, (this time equipping them all, and Sonic, with special bracelets that would enable them to be positioned normally in the No Zone) Zonic explained how Mogul got his power, just as Mogul had finished destroying all other Zones, except the Prime Zone and the No Zone. Zonic's hunch about Tails was the right strategy as all of the Tails merged into Titan Tails to stop Mogul and restore all of the Zones. (StH: #149, #150)

War with Dr. Nega
Some time after this, a mad man known as Dr. Nega was causing chaos while traveling the Cosmic Interstate and in the Zone Cops' attempts to stop him, a war between the Zone Cops and Nega started, causing the No Zone to be left in ruins. (StH: #197)

Zone Lockdown
Due to this war with Nega, a zone lockdown was initiated with a only a few worlds able to interact with Mobius Prime for stability's sake. While Sonic was taking Scourge the Hedgehog to jail, he broke loose but the two were quickly arrested by officers Zespio and Zector for violating the zone lockdown act and at Sonic's request, where taken to the No Zone via a Warp Ring to see Zonic. After Sonic and Scourge arrived and see the zone in ruins due to the war, Scourge escaped the custody of the trio and then tried to destroy the already ruined No Zone to avoid being arrested by the Zone Cops again, but Zonic caught sight of him and ordered the Zone Cops to arrest him as Scourge was now their main target. Zonic met up with Sonic and the Zone Cops and they battle Scourge. During the brawl, Zonic revealed that the Zone Cops had been fighting a villain called Dr. Nega who wrecked havoc in No Zone. They quickly captured Scourge thanks to Sonic's skills and Zonic's special Control Collar. Sonic then asked Zonic when he was taking away Eggman, but he revealed that Sonic-Prime has to fight a Robotnik to keep his zone stable. He then arrested Scourge and ordered his officers to take Sonic home. (StH: #197)
