Unicron Trilogy

The Air Defense Mini-Con Team could combine into the Star Saber

The Star Saber was the source of nigh-unlimited power for an ancient civilization. It was later responsible for the civilization's destruction via sinking into the ocean. Sonar's Mini-Con panel was left there and later recovered by the Decepticons. Ruin

Later, after invading the Autobot base, Megatron used Sonar to locate the other two Mini-Cons and eventually succeeded in forming the Star Saber for the first time in ages. His victory was short-lived, however, as Hot Shot stole it from him. Hot Shot was shaky in his command of the saber and at first did not put up a good offensive against Megatron. After words of advice from Rad White, Hot Shot harnessed the power of the Mini-Cons to defeat Megatron, cutting off Megatron's antenna in the process. Swoop

Hot Shot continued fighting and defeating Decepticons with the Star Saber, the Saber allowing him to easily slice off pieces of his opponents. While in a swordfight with Starscream, he was hit once, but Starscream's sword was cut in two by the Saber. But even with the Saber in his possession Hot Shot was no match for Scavenger, and was easily defeated. Afterwards Scavenger hinted to Megatron a legend of a shield that could counter the Star Saber. Overmatch

Hot Shot practiced with the saber but struggled once again against Scavenger. He eventually used the sword to cut away an unfinished bridge, causing Scavenger to fall. Gale In another battle they were transported, along with Sideways, to the Decepticon base. After a battle, Sideways was captured by Megatron, who offered a trade for the Star Saber. Hot Shot decided to agree to the trade, but as soon as Sideways was free he called back the Star Saber in the form of its three components. Sideways then turned on Hot Shot and knocked the Saber out of Hot Shot's grip and to Starscream, who then took control of it. Credulous

With the Star Saber in hand, the Decepticons won many battles and captured more Mini-Cons. Megatron later tricked Starscream into attacking him, and took the Star Saber as the Decepticon view shifted negatively against Starscream. Conspiracy Megatron used the Star Saber to attack Optimus Prime in super mode, but had his attacks parried. He was later thrown into a crevasse, but kept the Star Saber in hand. Trust

With the Star Saber, Megatron believed himself invincible. Reinforcement Megatron attacked Optimus Prime with both the Star Saber and the Skyboom Shield. Optimus Prime's gun was cut in two and his arm was damaged. With the help of Sparkplug, Optimus was able to steal the Skyboom Shield away from Megatron. Then the Star Saber and Skyboom Shield collided, causing a beam of light to head off into space. Decisive Battle

The Autobots attempted to figure out the origins of the Star Saber while Megatron figured out new ways to attack using it. Optimus later commented that the power released when it hit the Skyboom Shield was due to the "screams of the Mini-Cons." Vow When Starscream contested Megatron for leadership of the Decepticons, Megatron bet the Star Saber on the winner. Megatron won the battle and kept the Star Saber for himself. Rebellion

Thrust at one point asked for the Star Saber as the only way to guarantee Decepticon victory. During the battle, he let Megatron use it and never actually took possession of it. Tactician Megatron found himself increasingly frustrated with his inability to harm the Autobots due to the Skyboom Shield. He wounded Smokescreen once with the Saber, but found further hits once again parried by the shield. Linkup

The Star Saber was drawn toward the Skyboom Shield. Together they caused a signal that awakened the Mini-Cons that combined to create the Requiem Blaster. Desperate Later, in the jungle, Starscream used the Saber to battle Optimus Prime. The three component Mini-Cons turned the Saber off to protest the fighting. Sacrifice

After changing sides, Starscream used the Star Saber to attack Megatron and [[Thrust (Armada)|] and used it to block a shot from the Requiem Blaster. Optimus Prime then took it to attack Tidal Wave. Regeneration In the attack to save the Mini-Cons, Starscream again battled Megatron and was able to chop off Megatron's turret. Rescue On the adventure to Mars, Starscream threw a tantrum and sliced a few mountains with the Saber. Later when the Saber was in the presence of the Skyboom Shield and the Requiem Blaster, all three weapons shone light and then caused an explosion in space. Mars

When Starscream eventually turned sides again he took the Star Saber back to the Decepticon side. Crack He presented the saber to Megatron and was immediately threatened with it. All three weapons were then combined to power the ultimate weapon, the Hydra Cannon. Threaten

Armed with the Star Saber and Skyboom Shield, Galvatron led the attack on Cybertron and attacked Optimus Prime. Uprising Galvatron later almost handed the Star Saber to Thrust, but instead used it to attack Hot Shot, who had infiltrated the base. Wheeljack parried the attack. All of this prevented Thrust from stealing the Star Saber, so he instead ran off with the other two weapons. Dash When Demolishor was unable to catch the fleeing Thrust, Galvatron threatened him with the Star Saber. Drift Sideways then got angry at Thrust for not being able to secure the Star Saber with the Skyboom Shield and Requiem Blaster. Portent

Galvatron swiped at Starscream with the Star Saber then attacked Optimus Prime when Optimus attempted to negotiate a truce with the Decepticons. Optimus was able to catch the Star Saber in mid-swing. Starscream interrupted the battle, causing Galvatron to attack him. Starscream was able to dodge at first but then allowed himself to be run through. After pulling out the Star Saber from his chassis, Starscream attacked a hovering Unicron. Unicron retaliated, destroying Starscream utterly. Seeing this, Galvatron picked up the Star Saber and offered it to Optimus Prime, but Sideways appeared and stole it from his hand. Cramp

Returning to Unicron, Sideways shoved the saber into the ground, fully awakening him. Alliance It then became part of Unicron's body and the component Mini-Cons were said to be impossible to awake. Later, when Galvatron and Optimus Prime invaded Unicron's interior, Galvatron saw the Star Saber and reached for it. Tentacles surrounding it attacked Galvatron, causing him to recoil. Eventually the saber was awakened by a Mini-Con song, splitting into the component Mini-Cons. Origin

Nemesis Prime wielded the Vorpal Saber. After the [Autobots and the Decepticons landed on a strange world, they were menaced by a rampaging, powerful clone of Optimus Prime. The creature, calling himself Nemesis Prime, was seemingly defeated by Megatron when he fired the Requiem Blaster and blew the clone to pieces. However, the pieces reconnected with each other and Nemesis Prime formed the powerful Vorpal Saber as an extension of his own flexible, warping body. The Vorpal Saber disintegrated when the Mini-Cons arrived to save the other Transformers. Puppet

The Blizzard Saber is made up of the three Mini-Cons Beacon, Lens, and Quantum.

Argghhhh, my wrist!

Megatron also wielded an Energon Sword at one point.

Hot Shot, greviously injured, was regenerated into a new body by the power of Primus. His Cybertron Defence body so happened to have a sword with it. Sometimes he slotted it into his wrist, other times he held it.
