The Jupiter Spear is a weapon from Pretty Guardian Sailor Moon, formed when Sailor Jupiter reshapes her Sailor Star Tambourine into a lance. It carries no official title and appears to be a desperate, last-resort measure.
In the live-action Pretty Guardian Sailor Moon, Sailor Jupiter can convert her Sailor Star Tambourine into a spear, which fans call the Jupiter Spear. The series never gives the weapon a formal name, and its use reads as a final, desperate option.
The lance is meant for attack and for shielding the Earth. When Jupiter wields it, she channels the might of her home planet together with lightning. It is seen crackling with electric energy, which suggests it may carry lightning-based strikes, though no such attack is ever actually shown. In shape it calls to mind Poseidon's trident, an apt echo of Jupiter's command over electricity.
Sailor Jupiter is the weapon's sole wielder. In the final act she calls up the spear to strike down the Youma born from Princess Sailor Moon, hoping to save her. She and the other Guardians then try to close in around Usagi after fending off the Youma, but they cannot keep her from destroying the Earth and are beaten. The spear returns in the Special Act, where Jupiter uses it to defeat Queen Mio.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....

The Jupiter Spear is formed when Sailor Jupiter reshapes her Sailor Star Tambourine into a lance. This transformation is unique to the live-action Pretty Guardian Sailor Moon series.
The Jupiter Spear lets Sailor Jupiter channel the might of her home planet together with lightning, and it is shown crackling with electric energy, though she is never seen landing a lightning-based attack with it. Its shape recalls Poseidon's trident, echoing Jupiter's association with electricity.
Sailor Jupiter is the Jupiter Spear's only wielder. She calls it up in the Final Act to strike down the Youma born from Princess Sailor Moon, and again in the Special Act to defeat Queen Mio.
