Synthos
- Synthos is a bad bad thing in the Unicron Trilogy continuity family.

Synthos is the ultimate creation of the people of Sandokan, the culmination of generations of warfare waged upon themselves. Synthos is a living weapon created with the Dark Heart of Sandokan. His telekinetic power can turn anything around him into a weapon, making him very difficult to destroy. After 1000 stellar-cycles of civil war, Synthos represents the hope of all Sandokan— A Weapon to End War.
And end it he did.
Synthos arms himself with deadly plasma emitters, though he is capable of controlling literally all of the Sandokan's vast military infrastructure, including weapons capable of reaching out into local space. Though Synthos possesses vast destructive power, his sensory systems are susceptible to deception by cloaking devices, which can cause him to adopt a more cautious approach.
It is implied that Synthos could exist without the Dark Heart of Sandokan, but this would vastly reduce his abilities.
Fiction
Shortly after coming online, Synthos went mad and slaughtered the entire population of his home planet. A weapons system with no 'off' switch, he prowls Sandokon's blasted lifeless landscape in search of new prey, even looking out into space, searching for a means off the planet so that he can fulfill his purpose— destruction— on a more cosmic scale.
Synthos shot down the Autobot Override's ship Star Arrow as it passed near Sandokan. Though its crew was able to escape destruction.
When the Decepticon bounty-hunter Astrotrain came to capture the Autobots' cargo, Synthos struck a bargain for Force Chip technology, promising to steer clear of Decepticon territory when he escaped Sandokan.The Dark Heart of Sandokan
