Weaknesses
Decepticons share many of the same weaknesses as other Cybertronians.

Culture and society
Decepticons are typically concerned with such things as conquering Cybertron, defeating the Autobots, amassing large quantities of energon, developing powerful weaponry, and beating people up, though not necessarily in that order.

Decepticons are led by the most powerful of their ranks, most commonly Megatron. This tends to cause some conflict, given how generally every Decepticon thinks that they are the most powerful. Decepticons are also considered to be ancestors of the Predacons.

Decepticons are not exactly the most compassionate beings in the universe, but not all fight for greed. More than a few have a sense of honor, while others believe that Cybertron would be better protected by aggressive expansion. Ultimately, the Decepticons desire to protect their homeworld, even if it is at the expense of others.

In the Viron cluster, the Decepticons are classified as a subgroup of Predacons with vehicular alternate modes.
