Overlooked Sci-Fi Weapon of Coolness

I'm watching old Andromeda reruns, and I'm thinking that if I could only ever have one scifi weapon, this might be the one.

From Wikipedia:

The High Guard Force Lance (from Andromeda)

The Force Lance generally looks like a harmless metal rod approximately 1/3 of a meter in length which fires high energy plasma shots, but can extended to almost 2 meters and be used as a melee weapon. The Lance is keyed to its handlers DNA and can also be reprogrammed, a person will be electrically shocked when trying to use another's programmed Lance. It can also be used as a taser.

The Force Lance can launch a number of self-guided tiny attack drones (called “effectors”) that both target opponents and intercept incoming bullets and missiles.  It has a grappling hook function, it can be placed in a stationary position to be set on auto fire, & finally it can be used as a plasma grenade by setting it to overload.

So let's recap:

• It's a quarterstaff
• It fires plasma bolts
• It's a taser
• It fires self-guided drones that target either people, or incoming bullets and missiles
• It has a grappling hook
• It can work as a sentry gun
• You can use it as a grenade (but then you don't have one anymore)
• And...If anyone but you tries to use it, they automagically get tazed!!

Batman probably wishes he had one of these.
