Fun fact about Transformers, each Autobot has an opposite Decepticon

Here’s some examples:
Bumblebee and Starscream
On the Autobot side, Bumblebee is considered a scout to the team, being fast and agile he can take down Decepticons easily. Starscream on the other hand, is the leader of the seekers (in most stories) where the seekers act as the scouts for the Decepticons. Unlike Bumblebee though, Starscream is relatively weak and can take down (few) Autobots

Optimus Prime and Megatron
I don’t really need to say anything for them. Both are leaders of their side of war, one is evil one is good, and they literally have a fight in (almost) every single story.

The Aerial Bots and The Stunticons
These are teams that combine into bigger bots, or in other words Combiners, and you can clearly see the difference between them. The Aerial Bots, or Combiner name Superion, work cleanly together and are able to combine smoothly. They are one of the strongest Combiners of the Autobots. The Stunticons, or Combiner name Menasor, don’t work as well together, because when they are combined, they glitch out from time to time, as it is only the leader controlling Menasor rather than the team. They are a kinda strong Combiner of the Decepticons.
