The KO Cannon attacking Target Dummies. Note how it is possible to hit multiple enemies at once.

The KO Cannon is a Hardmode flail that autofires a red boxing glove projectile connected to the weapon's base by a short, thick chain. After striking a target or traveling 12 tiles, the glove retracts back into the weapon before being ready to fire again. The KO Cannon has a 1/5 (20%) chance of being dropped by Clowns.

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount. However, Ruthless might be preferred if the player already has very high critical strike chance.

Notes

The KO Cannon has no cooldown period; therefore its autofire rate is dependent only on the distance to its impact, meaning that an enemy or object in close range will cause a faster autofire rate.
Although technically a flail, the KO Cannon's projectile has no difficulty passing through terrain on its return trip.
In Don't dig up and Get fixed boi worlds, the KO Cannon receives the following changes:
- Switched place with the Chain Knife. As a result, it is dropped by Cave Bats instead of Clowns.
- Damage decreased from 40 to 18.
- Use time decreased from 28 to 25.
- Knockback decreased from 6.5 to 5.

Tips

Despite this weapon having a relatively short range, its higher knockback, base damage, and immunity to gravitational arcing make it very strong at close quarters.
Although generally not able to strike multiple targets simultaneously, its rate of fire increases significantly when at closer ranges. Therefore, the player will find fending off hordes of enemies easier once they begin to close in due to its high knockback.

Trivia

The Golem Fist can be considered a direct upgrade to this weapon.
If aimed to the left, the "KO" on its side will be mirrored.
KO is an abbreviation of knockout, a term originally used in boxing, which is also referenced by the boxing glove being fired.
