Bellamy's Axe

Axes are common, and can serve as utilitarian tools. As weapons, they are generally relatively easy to use for the amount of damage they can cause.

Bellamy Blake's axe appears to either be homemade or a re-purposed survival tool. Clarke Griffin used it to cut John Murphy down before he suffocated from being hung.

Axes are also used by Grounders in the battles.

Knives Edit

Murphy's Knife

Knives are useful tools, that despite their small size can still be effective as deadly bladed weapons. Charlotte used a knife made from scrap metal to kill Wells Jaha. John Murphy has used his knife to threaten his victims. Lexa used a Scottish dirk. Knives are also used by Grounders, too. During the Final Conclave at Polis, Kane reveals that the Blue Cliff warrior has two Corvo Knives.

Swords Edit

The Grounders used swords in close quarters combat and was used by Lexa after all of the Grounders cut a traitor to give the final kill. They also use these weapons in the battles.

Machetes Edit

Machetes are also used by Grounder warriors as weapons.

Primitive Ranged Edit

Spears Edit

A spear was thrown by a Woods Clan member into Jasper Jordan's chest. By inspection, the shaft appears to be made of wood while blade appears to be discolored iron or steel. Lexa also used a spear to kill Queen Nia.

Bow and Arrow Edit

Used by Grounders, all bows seen have been short bows made of wood.

Crossbow Edit

Only members of Floukru have been seen using crossbows.

Firearms Edit

M4A1 Edit

Unity Day 076 (Jasper, Raven, and Bellamy)

Raven, Bellamy, and Jasper with M4A1 rifles

The 100 found some packed for long-term storage in an old military base. While the rifles still function well, much of the ammunition has gone bad. The 100 used M4a1 rifles to ward off Grounders attacking the Delinquents' Camp.

FNH Five-SeveN Edit

FN Five-SeveN

Bellamy's gun: FN Five SeveN

Bellamy was given a semiautomatic pistol by Commander Shumway to kill Chancellor Thelonious Jaha. It ran out of ammunition after Wells Jaha shot the panther in "Earth Skills".

Beretta MX4 Storm Edit

Beretta MX4 Storm can be seen in seasons 2 & 5, used first by the security detail at Mount Weather and then by the prisoners from the mining ship. Presumably the standard issue sidearm for prison guards, which were later obtained by the prisoners.

Norinco QBZ 97 Edit

The bullpup rifle, known as the Norinco QBZ 97 chambered in 5.56x45mm NATO, is a pre-war Chinese assault rifle. it appears to be the main guard weapon used in the Ark. It is seen frequently in Season Two, used by the Camp Jaha guards.

It is unclear how the survivors of the Ark acquired them, but since it is Chinese-made, it is possible it was part of a payload of supplies sent to the Shenzhen before the creation of the Ark.


CAA Tactical Roni

CAA Tactical Roni Edit

This gun is seen used by Finn Collins from "Many Happy Returns" to "Spacewalker". It was given to him by Bellamy Blake at the end of "Many Happy Returns".

Minigun (unknown model)Edit

At the onset of Season Three, the vehicle used by various characters features a clearly visible minigun mounted on the front (to be used by the person in the front passenger seat). The weapon is of unknown origin, but likely originated in the now-vacant Mount Weather, as such a weapon would be illogical to use on a space station. Additionally, Mount Weather is known to have had an arsenal of heavy weaponry, such as guided missiles, so theorizing that the weapon originated there is not unrealistic.

Sniper Rifles Edit

These firearms are known as only used by the Mountain Men. They have very good scopes and are suppressed, the first time we see it being used is in Season Two while two Mountain Men soldiers were hunting down Clarke and Lexa with a Remington model 700 in episode Coup de Grâce. At the end of the Season Four finale, Clarke Griffin and Madi also have a sniper rifle, which has the written names of people who's been lost.[1]

In 2052, A.L.I.E. has launched nuclear missiles that have caused a Nuclear Apocalypse, including 27 ICBMs from China.

The "Damocles" bomb is a weapon made of Hythylodium from the asteroid Proxima VI. Hythylodium was kept in massive tanks that were attached to a rocket engine. Then it was propelled by it into the ground an exploded on impact. It could destroy a massive area and make it toxic.

One of the worms that got out of him, attacked Octavia and got into her body. Clarke managed to take out the worm and put it into a jar. Kara Cooper experimented on the worms.
