- Angolmois is an energy from the Beast Wars era of the Generation 1 continuity.
Anglo-Saxon Energy!
Angolmois energy is the life-force of Unicron. It is a powerful energy source which often times has completely random and unpredictable effects on the things it comes in contact with. It can upgrade a Transformer and give them new bodies, or it can lift mountains and freeze planets.
Just like Unicron, Angolmois is extremely chaotic.
Fiction
The Transformers: The Movie (1986)
When Unicron's body exploded at the climax of Transformers: The Movie, the Angolmois energy (that green electric-stuff) was sent hurtling through time and space.
Beast Wars II
It ended-up in the distant future, on the planet Gaia (which, in reality, was post-apocalytic Earth). It riddled itself into the planet's surface and began to have bizarre effects on the environment.
During a space battle with Galvatron and his Predacons, Leo Prime and the Maximals landed on planet Gaia after going through transwarp space. Realizing the destructive potential of Angolmois, Galvatron made it his goal to steal all of it from Gaia.
The Angolmois effected the Transformers on Gaia in many ways, including upgrading Megastorm, Starscream and BB, to name a few. Galvatron eventually sucked all the Angolmois from the planet using his battleship, the Nemesis. After a fierce battle which resulted in the death of Galvatron, the Maximals being trapped in a wormhole and the Predacons being set adrift into deep space, all the Angolmois energy aboard the Nemesis was sealed away in capsules and ejected into outer space.
Beast Wars Neo
The Maximal Elders, unaware of the fate of Leo Prime, ordered Big Convoy and his Maximal new recruits to investigate Gaia and see what was up. Unknown to Big Convoy, he was followed by Magmatron and his Predacons. After finding Leo Prime's black box, they learned about the Angolmois capsules and immediately set off to reclaim them.
The Maximals and Predacons then raced to secure as many capsules as they could. The Angolmois capsules were wreaking havoc all over the galaxy, causing great destruction on the planets they wound-up on.
Eventually, between the Maximals and the Predacons, all the Angolmois capsules were recovered. Then, the mysterious and insanely powerful Blentrons showed up, beat the mortal crap out of both factions and stole all the Angolmois capsules.
As it turns out, the Blentrons were creations of Unicron. They released all the Angolmois energy into the corpse of Galvatron, resurrecting Unicron. Unicron then attacked Cybertron and possessed Vector Sigma, turning the planet into his new body. Only by teaming-up were Magmatron and Big Convoy able to defeat Unicron and save Cybertron.
