Each one is disposed of by a typical gang manner, such as a generic "Punk #5" played by Paul Schrier sliding into the bowling pins when kicked in the back by Jason.

[3] In a second pilot, shown at Power Morphicon 2007, Schrier was playing a named character (Bulk) and was now the leader of the gang, which included Jason Narvy as Skull.

He turned up to his audition intending to be obnoxious, as he was tired of the industry at the time, which helped get the role; Narvy and Schrier quickly bonded during rehearsals.

[5] Bulk and Skull started out as bullies at Angel Grove High School, usually targeting the Power Rangers in the 'B plots' of the episode.

In the first-season episode "Foul Play in the Sky", which had footage shot later in production and then edited in later, Bulk and Skull were even shown with a normal hobby, plane-spotting and politely ask to join Kimberly and her Uncle on a flight; "A Pig Surprise" would have them happily looking after a pig; and in the three-part "The Ninja Encounter" in season two, when Bulk spotted a runaway baby stroller, he and Skull immediately sprang into action to help out, and the duo would spend the rest of the episode looking after the baby boy until his father escaped Goldar's clutches.

During this time, Bulk and Skull started showing greater intelligence and initiative than before, coming up with complicated plans and utilizing bizarre gadgets.

While a majority of their plans were harebrained, a few of them were actually clever, like making a cement cast of the Power Rangers' footprints so they can see if any civilians' feet match.

Unfortunately, Bulk and Skull lost their short-term memories in the process due to being flung back by the amnesia beam and landing on their heads.

Lt. Stone became a permanent character himself, frequently giving Bulk and Skull orders that they usually failed to perform, leading eventually to his anger (rather than just their humiliation).

Despite this, Bulk and Skull were close to Lt. Stone and took their new job seriously as they would be shown trying to perform police duties (albeit incompetently) and occasionally try to help people in trouble: in "The Changing of the Zords: Part I" they rushed to save children from drowning (who were not), in "Follow That Cab" they tried to stop a thief who'd stolen Kimberly's car and managed to apprehend him, ironically after they inadvertently helped him, and in "Rita's Pita" they used their own money as donations to an elderly home to cover for their mistake, and they assisted in a housing project in "Another Brick in the Wall".

When the Zeo Crystal was reformed and undid the time Reversal, Bulk and Skull, who were on playground swings and trying to see who could go the highest, where the first to return to their normal ages.

Paul Schrier directed a few "Mighty Morphin Alien Rangers" episodes, including "Attack of the 60' Bulk", which he also appeared in briefly, despite his character at the time being reduced to the age of a child.

During Power Rangers Zeo, Bulk and Skull remained members of the Junior Police Force (even getting a new motorcycle with a sidecar).

They remained members until Bulk's attempts to woo the police chief's daughter accidentally caused Lt. Stone to be fired.

In "The Joke's On Blue", they also had to clash with a rival gang of detectives, Humphrey and Bogart, who were trying to frame a new student named Robert for a series of practical jokes all over town, until Kat and Tanya helped expose the rival detectives as the practical jokers with the help of the owner of the novelty shop in identifying both Humphrey and Bogart as his best customers.

In the episode "Instrument of Destruction", Skull shows he is an adept classical pianist by playing Chopin's Revolutionary Etude.

After seeing Skull perform at a recital, Bulk was honestly moved and praised his friend, apologizing for making him feel insecure about his talent and joining him on stage to applaud him.

Detective Stone then reveals that normally they would have failed, but the examiners gave them extra points for completing the test during the monster attack.

Zeo concluded with Bulk and Skull accepting an offer to work for an agency in France on a top secret mission, They departed much to the dismay and frustration of Stone.

At the beginning of the movie, Bulk, Skull, and Lieutenant Stone are again seen working as police officers (the reason for this remains unexplained until the first episode of Power Rangers Turbo).

Due to the brain scramble, they come to be under the impression that they are Antonio Bandaras (Skull) and an unnamed German (Bulk), much to the annoyance of their inmates, Jason and Kimberly.

At the start of Power Rangers Turbo, Bulk and Skull are given one last chance to rejoin the Police Force with Lt. Stone.

They were transformed into Chimps so Narvy and Schrier would have time to work on a proposed spin-off series for the characters which would have seen them operate a hotel, featuring El Vez, the "Mexican Elvis" (a local personality in Southern California).

The next morning, the Rangers (sans Andros, who left to board the Dark Fortress) intend to turn themselves in to save Earth.

In the initial plans for in Space, Bulk and Skull were going to form a volunteer Citizen Force Group to protect Angel Grove while the Power Rangers were away.

The two would try to refer to more foot soldiers to one-up each other (including later monsters they had not seen on screen); Skull stated he was avoiding Phenomenous; and the characters are wary of Tommy because he's their boss and the real owner of Bulkmeier's.

In the original casting sides, Bulk and Spike were not present and the comic relief were two singing roadsweepers "Big Mack" and "Skinny Jack".

[11] In Mighty Morphin Power Rangers: Once & Always, though the two do not appear in person, they are briefly shown on a billboard where they apparently own a food company.

They are later seen during a party at Ernie's and assist the Rangers' young friend Fred Kelman and the other Kids in stopping the brainwashed parents of Angel Grove from leaping to their deaths.

Narvy claims that the video release The Good, The Bad, and the Stupid was put out as a "test market" and when "no one out there bought it", Saban cancelled the plans.
