Guns (or firearms) are handheld weapons used in many Sega Superstars series, although they have seen limited usage in main Sonic the Hedgehog stories. A gun in the hands of an aggressive assailant will often lead to the death of a victim, as bullet wounds to the head, heart and other vital organs are fatal. Guns are long-ranged alternatives to swords and are more accurate and deadly than thrown spears and shurikens. Within Sonic the Comic, guns are almost exclusively given to villains, helping writers to get across an anti-gun mesage.
- Guns were first seen on a wide scale within the Streets of Rage series, in the hands of almost every gang member. A bazooka was first used by Bananas to attack the heroes' Battle Wagon and then by Max Hatchet to destroy The Safe House. Another one was later fired to take down a helicopter carrying the vigilantes. As a twist to most situations, guns are sometimes used by the good guys, but they often prepared hand-to-hand combat. The battle wagon is fitted with twin front guns and a powerful cannon on the roof. Skates wielded a flare gun at the helpless body of Mr X and Officer Murphy was killed by three corrupt policemen with shotguns.
- Guns are sometimes seen in the Eternal Champions series, although they are not as effective as melee combat. RAX Coswell once participated in a Cyber-Dome before his death that involved him using Bio-Keyed guns to attack each other. The titular heroes ventured to this time zone to retrieve one of these keys, but unwittingly left it for Nakano to find and speed up his production of the weapon. Guns were later used by Chicago police to fight Larcen Tyler, but the cat burglar could easily relieve them of their firearms with his hooks.
- Guns are used exclusively by the villains in the world of Shinobi, by both the Neo Zeed and the Yakuza. Hired security guards attempted to capture and kill Joe Musashi with machine guns, but Joe rendered one useless by cutting the end off. The Yakuza are specialised in using them and succeeded in shooting the elderly Kotomi-sensei. Fortunately, the sensei was able to remove the bullet using magic. Other attempts to shoot their targets sometimes saw them shooting each other.
- Detective Case used a gun to try and capture Chuck D. Head in Who Killed Chuck?. At one point, Case pressed the gun against Chuck's face until he was scared against it by a sewer monster.
- Grouchio Marxio attempted to use a sniper rifle to shoot Knuckles the Echidna during his visit to the Carnival Night Zone. Grouchio missed and put the blame on Chicio Marxio, despite the boss still holding the rifle.
- A sniper managed to shoot Marko from Marko's Magic Football, but an extra life awarded by Captain Smirk awarded him another chance to evade the bullet.
- Many Badniks use gun substitutions as their main weapon to take out Sonic and friends. Eggrobo Badniks hold a literal gun that can be stolen and used by other people, like when Sonic stole it to shoot another Eggrobo and stole his jet pack. Commander Brutus attached a gun to his arm when his hand was ripped off by Super Sonic. Other Troopers also hold a literal gun, some of which have been seen to be very powerful.
- A whole armoury of guns were found underneath Ribble in The Curse of Zeon, while several others were given to Zeonites, one of which "killed" Bowie.
- Mister Shifter, a villain from New Tek City, attempted to shoot Agent X19 at point-blank range but the bullet was caught by Sonic.
- Another sniper rifle was handed to Tails by unicorn Forelock, granting him the perfect opportunity to kill Doctor Robotnik. Tails refused to commit the atrocity and Forelock revealed it was all just an illusion.
- Bungling crime duo Sid and Tone tried to use guns to fight Amy Rose and Tekno the Canary but fought amongst themselves and shot down the ceiling of a cave, buring some treasure.
- Agent X, now revealed to be Shayde, pulled out a gun to fire at Sonic when his plan was foiled but ended up shooting his teleporter instead. Shayde was returned to the Shadow Dimension and the Rusty Ruin Zone was destroyed.
- Tekno the Canary chose to use a gun while on Planet Romanus and was forced to shoot Amy Rose after defeating her in battle. Fortunately, she had already converted it into a transporter, sending Amy back to the slave pit. She later sent Clawbeast right into the lap of Emperor Zero.
- The police force of the Metropolis Zone attempted to use graviton cannons to defeat Chaos but they did absolutely nothing to it.
- Nack the Weasel shoots Tails out of the sky in Just Like Old Crimes, but the plucky fox survived and wasn't so slow next time.
- Big the Cat was shot with a gun, choice member of The Family member Harvestman. Fortunately, Big's fast reflexes allowed him to catch the bullet.
- The Household Keepers and Bounder Brigade of the Hill Top Zone use guns to kill their targets. When an image of Rouge the Bat pulled out a gun, the security forces tried to shoot the villain but only destroyed a priceless mural. Rouge's weapon was actually a dud with a "BANG" flag. Oswald is a sniper on the team, but couldn't shoot Rouge thanks to the smoke obstructing his view. Masad Akaan also carried a gun, but this froze after being stolen by Sonic.
