Gun del Sol

The Gun del Sol (ガン・デル・ソル) is a powerful solar gun from the Boktai series that can be used only by a person with solar blood running through their veins. The gun was originally created by Smith, a blacksmith from San Miguel, to the vampire hunter Ringo. Ringo later passed it to his son Django. This is the only weapon available in the first Boktai game. In Boktai 2 the Gun del Sol was stolen and Django uses other weapons, but can be recovered later in the game, and is only able to use the solar shot as it was damaged. In Boktai 3, most of the Gun del Sol's capabilities were repaired, but some features are still missing.

The Gun del Sol is composed of four parts that can be obtained during the game and can be customized: lens, frame, battery, and grenade. Some enemies and traps can be faced only with specific parts. The frame determines the attack method and capability of the gun. The lens determines the property of the shot and spread shot of the gun. As the lens increases in level, its attack power increases and the spread becomes wider. The grenade is a special supplementary ammo, with different types that can have a limited range or go throughout the entire screen. The battery is the energy tank of the gun. According to the type of battery used, the number of tanks may vary. In Boktai 3, the battery can't be changed and the grenade attachments were removed, but they can be used with one type of frame called "Bomber".

The Gun del Sol uses solar energy, which is obtained from the Solar Sensor in the game's cartridge. The more energy, the stronger the weapon is, but to much energy can cause the gun to overheat, and the player will need to wait some time till the gun cools off.

MegaMan Battle Network series
In the MegaMan Battle Network series, the Gun del Sol is a Battle Chip from MegaMan Battle Network 4 to 6 that attacks with a solar spread. By holding down the A button, player can reduce enemy's HP within the solar ray's range (2x2 squares front) in rapid succession (similar to Poison effect, but faster). This attack cannot be blocked by shields, and will continue as long the player hold down the A button. But it has a time limit and forbid MegaMan from moving. When used against a Darkloid in MegaMan Battle Network 5, their HP will continue to decrease after being attacked by Gun Del Sol chips (like a permanent Poison, but slower). This may refer to their "Darkness" origin, which similar to vampires and weak against sunlight. Stronger versions of the chip (Gun del Sol 2, 3, EX) have the same time limit of usage, but allows for faster HP reducing rate. Django also uses the Gun del Sol in some of his attacks. The Gun del Sol chips are part of the Program Advance Pile Driver.
