Jackpot (enemy)

Jackpot the Jack's Bot serves as the final boss of the story of Moxxi's Heist of the Handsome Jackpot. He is piloted by Pretty Boy and fought directly after fighting Freddie. He was likely built by Handsome Jack before The Handsome Jackpot was built, and was installed with a variety of lasers, missiles, incendiary fire generators, and critical repair functions (that only work if you pay). He was also installed with a potent "Blood Cooling system".

Appearance and Function
The Jackpot is roughly four times larger than the player character, and piloted by Pretty Boy via the chest-controls. It is entirely silver metallic in color, and imitates Handsome Jack in appearance. Possibly due to its size, the bot cannot maneuver quickly unless using its thrusters located on its hands and feet, and tends to instead walk around the arena while attacking. As it loses armor, however, this handicap seems to disappear as the bot begins frequently levitating and moving, until its fourth phase where it is almost entirely airborne. It was designed with a series of laser cannons and missile launchers on its hands, mouth, and back, and can shoot flames from its palms and feet both as thrusters for movement, but also as flamethrowers for combat.

The Jackpot has several critical repair functions to return to functional order during combat. During this time, it has an impenetrable shield, but also cannot attack. Jackpot was also seemingly installed with a payment system allowing the bot to repair itself but only if the pilot pays for it first. It also has a voice system that offers both critical repair plans and a "High Interest Payment Plan". The latter is used in its fourth phase.

During its fourth phase, it's revealed that the Jackpot was installed with a "Blood Cooling" mode, which can be used to repair the body instantly, but also draws blood from its pilot as a "Down payment" via needles. Whether Jack intended to use that function himself or not cannot be certain, but Pretty Boy does use it, although he was unaware of what the function actually did and only agreed to it when the Jackpot offered after Pretty Boy couldn't afford another standard repair.

Story
Once the Vault Hunter reaches the control station aboard The Handsome Jackpot, they will meet face to face with Pretty Boy, who has Timothy locked in a laser-cage near the console (close enough to it, but too far to actually reach without hurting himself). Pretty Boy will stroll closer to the player, before laughing and saying "Jackpot". At this point, The Jack's Bot will land from the ceiling to the ground, and grab Pretty Boy, placing him in his chest, and the fight begins.

Once the boss has its first phase ended, Jackpot will offer a critical repair in exchange for payment. Pretty Boy happily pays the fee, and the bot continues repairing while Pretty Boy calls in Loader Bots to attack. However, once the robot is downed again, it will offer a high-interest payment plan. This time, Pretty Boy will deny, only paying the original fee, and the Jackpot will accept. Once the Jackpot goes down, it will inform Pretty Boy that he has insufficient funds. It will once again off the High-Interest Payment Plan, and Pretty Boy accepts remaking "I'll pay it all back anyway". The Jackpot will then extract a "Down-Payment", and Pretty Boy will remark about needles before screaming in pain as the Jackpot enters "Blood Cooling Mode". The Jackpot enters its final phase, but is still soundly defeated with Pretty Boy killed from inside.

Gameplay
The boss has a total of four phases, so be sure to prepare your equipment and purchase ammunition if necessary. while enemies and ammo crates litter the environment, it may be difficult to reach and grab their contents during the fight while being bombarded by the Jackpot. It helps to carry a corrosive weapon for the first three phases.

The boss starts with a singular armored health bar in phase one. During phase 1, it will use many attacks that will be repeated throughout the boss fight. Be aware that the statues in the arena are easily destroyed by the bot and do not offer any cover from his attacks. The weakened joints and the head are critical points, with some being easier to hit as the boss progresses. The laser blasts from the boss count as Shock damage, and the boss has heavy use of Incendiary damage, meaning it will easily remove your shield and then deal heavy damage to the character underneath.

The boss is capable of standing still and focusing its hands to unleash a steady laser beam that can track towards the player, necessitating moving out of its way via strafing, and can also fire a series of laser blasts from its palms while it stands still or moves around. It can also launch bombs from one hand and laser blasts from the other, one tracking your current location and another trying to hit your intended location as you move. The hands also have access to a flamethrower, which can be particularly devastating if the player has lost their shield. The boss can also focus on two different targets at once with its hands, allowing it to fire at two players simultaneously, so aggro may be split amongst a party.

The boss has use of a utility move in which it places a palm on the ground, then quickly creates an explosion and launches itself backwards. Sometimes it will do this in reverse, where it will kneel, power up its thrusters, and launch itself forward at the player instead. When done, the Jackpot will leave a flaming trail and do a quick spin with its lasers. It can also stand still and start hip-thrusting, and let loose a set of five PP Loaders which can be used for second winds, but also can be startlingly accurate and pose a threat. The player has a few seconds to attack the PP Loaders before they stand up after first being spawned.

At some times, the boss will stand still and emit five beams from its mouth directly at the floor near its feet, then will lift its head to sweep the beams across the floor. The player has to maneuver between the lasers and watch how they will rise to avoid heavy damage.

Once the health bar has been emptied, the metal coat on the robot will be blown off, and the boss will become entirely immune to damage. At this point, the boss will spawn multiple Loader Bots to come to its assistance while Pretty Boy tries to fix the robot (on subsequent fights, his dialogue is absent, but it still enters a recovery phase where the player must wait for the repairs to finish). The boss will not wait for the loader bots to be destroyed, and will get back up to fight regardless. During phase 2, the boss will use hand missiles more often, and will occasionally kneel down and fire a salvo of missiles from its back which can be dodged by moving quickly. The missiles do not have a reticle on the floor, instead trying to seek the player while in midair.

During phase 3, more of the armor on the Jackpot's limbs will be removed, and the Jackpot will add a powerful AoE attack involving the thrusters and laser. When the Jackpot lifts off the floor, it will fire its lasers directly at the floor and begin spinning rapidly. The flames resulting will spread out in a large circle and will cover a large portion of the arena. There is no guaranteed way to avoid the attack other than to run to the furthest edge of the room. Standing next to the bot when used is extremely dangerous, as the resulting flaming tornado can hit multiple times.

The fourth phase is the only phase that is functionally different. The boss no longer has an armored health bar, but instead has a red health bar. Additionally, the boss will be floating around almost constantly during the fight, and will attempt to constantly chase the player to deliver a series of melee blows in the form of large sweeping kicks and punches, regularly slamming into the ground to attack and performing large-area dashing attacks. The boss tends not to sit still for long and will be constantly darting about the environment. The long repair time between phases is nixed entirely. The boss will rise back up within seconds of being downed and become highly aggressive, and the Loader Bots that spawn between phases will still spawn despite this. This phase does, however, have the lowest health pool of the four phases, and goes down much faster.

Glitches

 * During the back jump, the boss can accidentally move itself into the wall geometry near the entrance. The boss will self-correct itself after its animation stops, but it may lead to shots missing and hitting the wall instead
