Below is a list of various weaponry used in the show.
Star Command
Standard Issue
Star Command laser
From rookie to captain, the Star Command laser is always with any Space Ranger. It can be set to either weld holes and cracks, stun an enemy or blast them out of the sky or atomize objects. It can be rather weak at times, and, with the appropriate alloy (diabonic for example), can be resisted.
Heavy duty laser cannon
The most powerful version of the Star Command laser cannon. It emits an orange laser charge, which could mean it's more powerful, since the traditional Star Command laser charge is red. The one you see here has a fancy paint job. It also comes in green (as seen in "Holiday Time") and blue.
Standard laser cannon
This cannon also emits an orange charge, so it's also powerful, but you need to be precise, as a poor shot could rebound off something weak, such as a bar table.
Small laser cannon
This is incredibly powerful and very portable. It can be used by first mission rookies as well, as is seen in "Revenge of the Raenoks".
Only for the experienced
Star Command photon bazooka
Only ever used by Buzz and Commander Nebula in the series, the bazooka is just about the most powerful piece of weaponry in the galaxy, with enough power to smash an asteroid to cosmic dust.
Star Command low range bazooka
A smaller but almost equally powerful version of the Star Command bazooka.
Warp Darkmatter
Warp Darkmatter has many weapons built into his mechanical arm.
Flamethrower
Warp has a flamethrower as a feature of his mechanical arm.
Laser gun
When he was still a Space Ranger, he also had a laser gun in his chest in the suit where the insignia is. He still has one when he works for Zurg.
Arm laser
When he was still in Star Command, he had a wrist laser like many other Space Rangers. Now a part of Zurg's forces, his mechanical arm has a plasma laser in it.
Bomb
Warp's mechanical arm can fire bombs from the shoulder.
Plasma Cannon
In the episode NOS-4-A2, Warp wielded a plasma cannon, which was outlawed by the Galactic Alliance. The weapon, however, was reduced to nothing when NOS-4-A2 absorbed its power.
Zurg
Ion-blaster
Zurg with his ion blaster
Zurg's signature weapon with three barrels. It can fire from all said barrels at the same time or just one by one. It is activated by squeezing the trigger.
Hyper Death Ray
Death ray made by Zurg and placed on Rhizome at the Spa. He has his Grubs use it to target Star Command. It supposedly causes more death than just a regular death ray. It appears in the episodes "Stress Test" and "War and Peace and War".
Zurgalatior
A weapon made by Zurg to blow up Star Command. It appeared in "Super Nova" and "War and Peace and War".
Heat Ray
Not really used as a weapon. Instead Zurg uses it to heat a field of crops contaminated with a mutagen that makes cucumbers into Killercumbers. It is used in the episode "Root of Evil".
Disintegrator Ray
Zurg attempts to fire this weapon at Buzz Lightyear.
Eye Lasers
Zurg can fire lasers from his eyes. He can also melt objects just by looking at them, so it might be heat vision.
Others
Savy
Plazooka
Plazookas are illegal bazookas that fire blasts of plasma. Apparently they are extremely dangerous. They're light enough for Savy to use. They are seen in the episode "The Slayer".
