Protesters are people who oppose a certain group or idea and vocally voice their disapproval or desire for change. Protests, rallies organised by these protesters, can range from peaceful displays that aim to grab somebody's attention, to violent ones.
History
Several protests have broken out in Sonic the Comic over the years, many of them directed at tyrannical leader Doctor Ivo Robotnik and all of these in the Metropolis Zone. The first was a show of strength against Robotnik and his new statue in Sector Alpha 34. One Mobian was able to climb onto "Robotnik's" moustache and was aiming to paint something when the Special Badnik Service arrived. Sonic the Hedgehog and Tails defeated the powerful Badniks whilst the protestors used a bomb to destroy the statue.
After Robotnik became more ruthless, protests quickly vanished. However, a rally in Metropolis Park was attended by Ebony and Pyjamas when news broke about a plan to demolish the Elder Tree and his family. Knuckles the Echidna arrived in time to destroy the assembled Troopers but soon found himself caught in battle with Omen and his Armourillas. With help and compassion from the furious trees, the protestors were allowed to leave and the entire area was fenced off.
Towards the end of Robotnik's despotic rule, the Freedom Fighters were captured during a routine mission in the Metropolis Zone. The gathered citizens remembered how many times their heroes had saved them and decided to fight back. A massive protest was later held outside of Citadel Robotnik, with Cat Adie of Zone At Ten covering the story. The protest was dispersed when riot Troopers arrived and even more Badniks arrived as reinforcements.
Post-RBR
Now that Robotnik was no longer the leader after The Final Victory, the Mobians found no reason to protest. One New Year's Eve, Mobius came under attack from Colonel Granite and his invading army. In the confusion, Sonic found himself on Planet Earth, namely London at New Year. The hedgehog was baffled by the pollution on the planet, but his opinion was shared by a group of protesters. After they realised he was not in fancy dress and was a real alien, they took him to Downing Street and waited as he spoke to the Prime Minister.

Many years after Robotnik's defeat, certain factions of Mobius began to grow restless. The Doctor Robotnik Appreciation Tribe had been campaigning and plotting for their master's return for years, without any success. With many evil plots failing and their leader, Grand Chief Whip, arrested, the "tribe" turned to non-violent acts. At Christmas 2007, D.R.A.T. elected to hold a peaceful rally that supposedly went without any hitches. Sonic was eager to beat up the protesters, but Tails informed him that it was a peaceful rally and Police Chief Bodger only wanted the fox to watch over proceedings.
A vicious smear campaign against Sonic by the Kane Broadcasting Company earned the ire of many citizens, particularly Norris Wimple. Angry that his hero had been mocked on The Harold Hilltop Show, the geek formed Mobians Against Sonic Hatred (M.A.S.H.) and stormed the KBC studio. Harold Hilltop was rescued by Sonic, causing his own fans to go against him.
Following Robotnik's return and launch of the New Robotnik Empire, a new wave of terror spread across Mobius. Scared of the villain's new power, a group of protesters suggested starting peace talks with Robotnik. In reponse, the paramilitary group S.P.E.A.R. dispersed the peaceful citizens with tear gas.
