Notorious B.I.G

"This Stand breaks... every single rule I've known. There is no host... He's already dead... on the runway in Venice."

- Giorno Giovanna about Notorious B.I.G, Chapter 535

Notorious B.I.G (ノトーリアス・) is the Stand of Carne, featured in the fifth part of JoJo's Bizarre Adventure, Vento Aureo. Notorious B.I.G is a mass of flesh that feeds on any type of energy and automatically tracks the fastest object in the vicinity.

Appearance
In its brief appearance with its user alive, Notorious B.I.G seems humanoid. It wears a striped half-mask rising in a peak above its head and extending over its right eye. Its teeth are bared in a snarl, although it's unclear if this is a permanent expression or merely its reaction to Carne's injuries.

After reactivating itself following its user's death, Notorious B.I.G. begins developing a body of blobby flesh. Once large enough, it develops a crude form with two small limbs and a tail. It gains the eyes and mask of its previous form, along with armored bands on its body and shoulders and tiny, wheel-like "hands" at the ends of its arms.

After consuming enough matter, Notorious B.I.G undergoes a second transformation into a much larger monster. It becomes big enough to fill up the entire end of a plane's cabin and its arms become two stretchy tentacles. Its pointed helmet now curls over the top of its head and the Stand now possesses a mouth filled with blunt human-like teeth.

Personality
Notorious B.I.G. seems to have an animalistic personality, seeking only to devour things to further its growth. However, it appears to communicate with Giorno when it begins to develop on his arm, revealing information about itself that its current target couldn't possibly know (such as its name and the nature of its existence).

Abilities
Notorious B.I.G is one of the few Stands able to exist even after its user's death. Coupled with its ability to grow by absorbing energy, even that of attacks, Notorious B.I.G can be said to be truly invincible. However, as an automated Stand, it can be bypassed.

Post-Mortem Activation
While Notorious B.I.G can be summoned while Carne is alive, the Stand is said to only activate upon its User's death, drawing energy from Carne's grudge. This is one of its main features and gets rid of a potential weakness. Initially, Notorious B.I.G seems to have no body after the death of its user, instead constructing one by absorbing matter and energy from an outside source. As this body is made of physical matter, it is vulnerable to mundane damage such as being flung into objects or getting impaled; however, any surviving pieces will remain active and capable of regenerating themselves.

Energy Absorption
Upon activation, Notorious B.I.G slowly infects anyone that has touched the remains of its user and eats away at flesh and energy in order to grow a body; this includes Stand energy and energy from automated objects like an engine. Through this ability, Notorious B.I.G can grow to a great volume with enough energy, eventually reaching a size comparable to a jet plane. More importantly, one speck of it can completely recover from near-destruction as long as it reaches a source of energy to feed on, making it nigh-impossible to defeat.

Its ability to absorb Stand energy makes it immune to Stand attacks, enabling it to seek out Stands in order to feed on them.

Partial Symbiosis
In its initial growth phase, Notorious B.I.G. can influence its host's body, causing them to perform actions without being consciously aware of them. After infecting Giorno, it somehow made him take some of Carne's fingers and put them into a plane's freezer; later, it used a pen to write out Giorno's thoughts on the wall and window.

Speed Detection
While Notorious B.I.G is blind, it can detect movement around itself, driving it to automatically attack the fastest moving object within range. After detecting the object moving fastest with respect to itself, it accelerates itself until it can latch onto its target; at one point, it becomes fast enough to catch up with a plane flying at 800kph. This trait makes Notorious B.I.G.'s behavior predictable if one is aware of it​​​​​​; the Stand can be distracted with various objects like the moving hand of a clock or a motorized seat​​​​​​  as long as nothing is moving faster than it. This also secures its prison in the ocean; the constant motion of waves and currents confuses Notorious B.I.G. to the point where it can no longer attack anything besides the odd passing boat.

History
Notorious B.I.G was originally the humanoid Stand of Carne, though nothing is known about its abilities then. Carne is sent on a mission to kill Passione's traitors, but is immediately killed by Mista. However, it is eventually revealed that Notorious B.I.G survived after Carne's death and latched onto Giorno's body when he attempts to confirm the enemy's demise, only making its presence known well after the plane takes off. Consuming Giorno's arm to grow, it attacks and incapacitates Mista and Narancia in rapid succession.

Although Giorno succeeds in throwing the Stand outside by cutting off his remaining hand, it quickly catches up to the plane and begins to attack Trish before shifting its focus to Giorno's brooch, which Gold Experience turned into a hand earlier. Trish's attempt to protect Giorno's hand leads to the awakening of her Stand Spice Girl, which allows Trish to impale and seemingly destroy Notorious B.I.G. In actuality, a piece of the immortal Stand entered the engine room and absorbed the energy of the engine, causing it to grow huge.

In defiance of Bucciarati's plan to crash the plane, Trish tears the plane apart with Spice Girl, turning the cockpit into a makeshift parachute while the majority of Notorious B.I.G chases the larger, faster-falling part of the plane into the Tyrrhenian Sea. While a small piece of the Stand is found on Abbacchio's hair, Bruno attacks it with Sticky Fingers, causing it to attach to his arm. Trish then cuts off his arm to send it into the sea. Notorious B.I.G remains alive and active in the Tyrrhenian Sea, occasionally chasing down and destroying quickly-moving ships; this behavior leads sailors to call it "'s stomach".

Trivia

 * Araki admits that he created Notorious B.I.G simply as an opponent for Trish to fight and enjoyed drawing Carne more than the Stand itself.
 * The anime adaptation changed the romanization of the Stand's name into Notorius B.I.G.
 * Notorious B.I.G's ability or naming scheme may be based on the Notorious B.I.G. album "Life After Death", which was released a year prior to the stand's debut.
