Magical Convergent Cannon: Jupiter

Magical Convergent Cannon - Jupiter (魔法集束砲 ジュピター Mahō Shūsoku Hō: Jupitā, translated as "Magic Focusing Cannon: Jupiter" in the Funimation dub) is a type of Magic weapon used by both the Phantom Lord and Grimoire Heart Guilds.

Description
The Magical Convergent Cannon - Jupiter is a powerful weapon feared by all. When fired, the cannon releases a compressed beam of energy that wreacks destruction wherever it passes. One blast from the cannon was enough to completely shatter Erza Scarlet's Adamantine Armor, an armor renowned for its extremely high defensive capabilities, to pieces. Had the armor not intercepted the blast, members of Fairy Tail feared that one blast from the cannon would be enough to completely annihilate their guild and the surrounding area. Additionally, the Magical Cannon has enough power to significantly damage a Titan-empowered Makarov Dreyar, who, in that form, is well known for his enhanced strength and durability; a further testament to the overwhelming destructive capabilities that Jupiter possesses.

Appearance
The cannon in Phantom Lord's possession is a large, round wooden structure held together by many metal rods and bolts. The barrel of the cannon can be extended. The muzzle of the cannon is completely metallic, and is obtusely shaped. In the anime, Phantom Lord's cannon is portrayed slightly different. The barrel is slightly longer than the one in the manga, and the cannon itself is composed completely of rusted metal. In addition, aiding the in the cannon's extension are four, long, metallic attachments hooked on to each of the barrel.

The cannon in Grimoire Heart's possession is composed entirely of metal, unlike Phantom Lord's, and is shorter, with flat pieces of metal sticking out of the barrel at odd angles. In the anime, Grimoire Heart's cannon appears almost exactly like Phantom Lord's, with only one small exception: the metal appears newer and shinier, as opposed to Phantom Lord's old and rusty.

Power Source
The power source for Jupiter is, fittingly, an extremely large, dark lacrima, which is connected to by many cables, which in turn, are connected to the floor and ceiling of its station, feeding Magical Power into the cannon. In the anime, the power source for the cannon is relatively the same, except that instead of cables feeding the lacrima Magical Power, there are four other, smaller, lacrima that transfer Magic Power to the aforementioned larger one. The recharge time for the Magical Convergent Cannon - Jupiter in Phantom Lord's possession is fifteen minutes. The recharge time for the cannon in Grimoire Heart's possession, if one exists, is unknown.
