Weapon 1: Blaster pistol
Just your basic laser pistol, Captain Jack uses them all the time
Weapon 2: Dagger
While in concept a basic dagger it's made of a rare metal called Strintillium that is stronger then all Earth elements (though not necessarily all aliens), Impervious to blaster fire and damage from bullets it works well as a defense as well as a non-suspicious in ancient times short-range weapon
Not really a weapon: Time-Vortex Manipulator
