Generation One

Prior to the events of G1, Bonecrusher, alongside his fellow Constructicons are originally peaceful neutral Autobots who build Crystal City & are friends with Omega Supreme. Alongside his teammates, Bonecrusher was brainwashed & reprogrammed by Megatron's Robo-Smasher into serving the Decepticon cause. He & his team send Omega Supreme on a fool's errand so that they can destroy their precious creation: Crystal City. After destroying it, he was hunted & reprogrammed by Omega Supreme back to normal but the collosal Autobot's efforts were a failure as the Robo-Smasher's brainwashing can never be undone & instead, it upgraded Bonecrusher & his teammates with a new ability: to merge into Devastator, who then tries to brainwash Omega Supreme with the Robo-Smasher, only to fail as he struggled to free himself. This encounter left Omega Supreme into an emotionless robot who swore vengeance.

Bonecrusher first debuted in season 1 episode "Heavy Metal War". He is first seen with his teammates stealing construction materials from humans & delivering them to Megatron & the Decepticons. Megatron later send him & his team into the Ark to destroy Teletraan-1, only to be stopped & exposed by the Dinobots, forcing him to merge into Devastator. Devastator was tricked by Hound's hologram of "Halonix Maximus" & was shot by Optimus on the chest, causing the huge Decepticon combiner to disassemble & fell into the lava.

Bonecrusher however survived the fall & reappeared in season 2 as a recurring minor villain. He is seen in the episode "City of Steel" with his teammates bringing down the Empire State Building & replacing it with a Cybertronian fortress.

In the episode "Autobot Run", Bonecrusher aided in the creation of the Transfixatron, a device meant to disable transforming into robot mode that keeps the Transformer into alt mode. He is also seen tossing a disabled Jazz aside after he attempted to protect a disabled Ironhide. He also merged with his teammates into Devastator when the Autobots regained their transforming ability, only to end up having a taste of their own medicine.

In the episode "The Core", Bonecrusher was tasked into creating a massive drill into gaining geothermal energy from the Earth's core & patrolling it. Chip Chase came with an idea to make Devastator turn against his allies by secretly planting dominator discs into the Constructicons. Bonecrusher is among these few who have been planted with dominator discs & once he & his teammates merged into Devastator, he soon went under Autobot control. Megatron knew of this scheme & fought back by regaining control of their champion. Chip & Wheeljack fought back by activating the dominator discs again. Their fight over control of Devastator fried his logic circuits, causing him to go berserk & destroy everything on his path, regardless of faction. A conjoined forces of the two sides were able to calm him down & disassemble back into the Constructicons. Bonecrusher & his teammates then decided to stop the massive drill they themselves created by merging into Devastator, while telling Scavenger to grow a robo-spine after the little peeptalk & diving into the lava to stop the drill, which had been a success.

Bonecrusher appeared in the episode "The Master Builders", where his leader Scrapper made a deal with Autobots Grapple & Hoist in building his Solar Power Tower, while claiming they "left" the Decepticons. It went poorly at first but Bonecrusher suggested of "offlining the two Autobots. They returned to the headquarters where they are greeted by a furious Megatron & his Decepticons pointing their weapons at them. After Scrapper explained, Megatron allows them to return to the Autobots with a present. They brought a cargo of energon cubes, carried by Long Haul to serve as "proof" they left the Decepticons. Bonecrusher & his teammates then began stealing construction materials from the humans to help Grapple in his Solar Power Tower. After successfully finishing the tower, the Constructicons merge into Devastator & betrayed Grapple & Hoist, while giving the tower to Megatron as a prize. The Autobots soon arrived, after gaining suspicion & fought Devastator by tricking him into crushing the tower itself. With the tower destroyed, Megatron & the Decepticons retreated.

Bone made a brief appearance in the episode "Microbots", demolishing the forest to clear a path for the Decepticons on their search for the Heart of Cybertron.

Bonecrusher was temporarily seen as a "heroic" Constructicon by the humans in the 2-part episode "Megatron's Master Plan" thanks to Megatron making a bargain with Shawn Berger. After Megatron reveals his true intentions, which in turn left Berger humiliated, Bonecrusher & the Constructicons were tasked of enslaving the humans & guarding them. He was soon driven away when the Autobots returned from their exile.

Bonecrusher once again reencountered his old friend Omega Supreme in the episode "The Secret of Omega Supreme", were he was owned by the latter.

In the 2-part episode "Desertion of the Dinobots", Bonecrusher & his teammates were then tasked into guarding the Decepticon Space Bridge delivering Cybertonium from Shockwave from intruders. He tried to drove off the Dinobots, only to fail so they merged into Devastator with the exemption of Scavenger, who was caught offguard & still failed to stop the Dinobots.

Bonecrusher & the Constructicons also served Blitzwing in the episode "Triple Takeover" after he & Astrotrain overthrowed Megatron & Starscream & made a bargain with them. They also build a trapped labrynth to capture Autobots & turn their remains into his throne. Due to Blitzwing refusing to end the bargain & insulting them into building a bridge & jump off of it, Scrapper ordered the Constructicons to merge into Devastator as a revenge & claim their end of the bargain. Even when Megatron returned & defeated Blitzwing & Astrotrain, this did not calm Devastator as he continued to fight the Decepticons out of anger, forcing them to fight him. After defeating the Decepticon combiner, he is scolded & given a warning.

In the episode "Starscream's Brigade", Bonecrusher & the Constructicons were assigned by Megatron in defeating Starscream's new minions: the Combaticons, only to be defeated. He & his teammates' combined form is also no match for the Combaticons' combined form Bruticus, who easily defeated him. Devastator's defeat is soon avenged when Menasor arrived & defeated Bruticus.

Bonecrusher made an appearance in "Transformers: The Movie" as one of its minor villains. He joined Megatron's Decepticon forces into attacking an Autobot ship, killing Ironhide, Prowl, Brawn, Gears & Ratchet in the process. He then joined the attack on Autobot City by merging with his teammates into Devastator to breach the gates, only to be defeated by the Dinobots & ended up retreating to Astrotrain. With Megatron in a dying state, the Decepticons began to argue who should be the new leader. Scrapper suggested Devastator should be the new leader & Bonecrusher & the rest of the Constructicons supported him. Rumble & Frenzy in turn refuses & suggested Soundwave instead & uses their piledriver against Devastator, causing him to disassemble. Due to the heavy load, Astrotrain convinces the Decepticons to dump their casualties. Bonecrusher suggested a fight of the fittest so they could dump the weak Decepticons. After the fight, Bonecrusher & the rest of the Decepticons then dumped Megatron, Thundercracker, Skywarp & the Insecticons into space. Bonecrusher was also present in Starscream's coronation as the new Decepticon leader as well as his death at the hands of Galvatron. He & the remaining Decepticons were tasked in hunting down the Matrix of Leadership.

With the roles of the Constructicons diminishing into minor roles, Bonecrusher is seen alongside his teammates in the 3rd season as minor antagonists. In the 5-part episode "5 Faces of Darkness" after the events of the movie, Bonecrusher & the rest of the Decepticons are exiled on the planet Chaar. He & his teammates quickly rushed to get energon scraps from Astrotrain, only to be interrupted by Menasor. The Constructicons merged into Devastator to immediately claim their share but Bonecrusher is exhausted so he fell of, causing Devastator's defeat from Menasor. He was punched on the back by Scavenger to take his energon share, while calling dibs on it. After making an alliance with the Quintessons, Bonecrusher & the Constructicons build Trypticon out of a populated human city.

In the episode "Carnage in C-Minor" Bonecrusher & the Constructicons constructed a giant set of engines on a meteorite meant to destroy Metroplex. They plan was interrupted by the Autobots so Bonecrusher immediately ordered the Constructicons to merge into Devastator, only to be flattened by a cunning Broadside, who transformed into his aircraft carrier mode. He also merge into Devastator to stop the Autobots on Eurythma, only to be blasted by a precise shot from Perceptor.

Bonecrusher is among the Decepticon forces who attacked the exiled Autobot planet Paradron, homeplanet of the Autobot Triple Changer Sandstorm, in the episode Fight or Flee.

Bonecrusher was last seen in the 3-part season finale of season 4 "The Rebirth" as one of the Decepticon forces who attacked Cybertron.

Transformers: Energon

Bonecrusher appeared in the Japanese anime Transformers: Energon. Unlike his original depiction, this version of Bonecrusher is nothing but a mindless drone who never speaks & instead transforms into a front-end loader with a breaker attachment on its back (which can transform into a rake) & forms either the right arm or left foot of Constructicon Maximus. He shares the same body type as Sledge.
