Laser Lance

Laser Lances are Level 5 alien tech/weapons. They are the primary weapons of the Forever Knights. They were introduced in Ben 10: Alien Force.

Use
Laser Lances are Level 5 Alien Tech (most of Earth's technology is either Level 1 or Level 2, while the Omnitrix is considered Level 20) and is illegal to sell Level 5 tech to people on Earth and is run on a etherpoint energy cell a dangerous technology way too advance for humans.

They are the most commonly used alien weapon by the Forever Knights.

Laser Lances can be a bit of a double-egde sword of sorts as it has been shown that if used after it has been damaged it can overload producing an explosion that can vaporize it uses and anyone unfortunate enough to be caught in the blast. This drawback was shown in Ben 10 Returns: Part 2, when a Forever Knight uses his damaged Laser Lance despite a warning from Magister Labrid and the knight is killed by the ensuing explosion. Also Kevin would likely have been killed by the explosion as well had not Magister Labrid push him out of the way. Following the Laser Lance explosion, Magister Labrid tells Kevin "That's why level 5 technology is illegal on earth, humans just aren't ready for it."

The Magister Labrid has Ben (as Echo Echo) destroy most of the Laser Lances shortly before it is discovered he had been fataliy wounded. However Kevin managed to save one which, Gwen later used to find the DNAliens base.
