So the EggSpark turning them into the Deceptihogs, giving them robotic weapon-toting bodies based on a multitude of Decepticon warriors from across the multiverse, really could have spelled big trouble for their frequent targets, the Flock (now converted to the Autobirds).
However, the two sides have been forced to cooperate, as the Eggbots are trying to cyberform the entirety of Piggy Island. They don't get along well, but hey, they're trying.
There are a lot more Deceptihogs than there are individual "named" Piggies; each major Pig seems to have been duplicated, plus there are numerous "variants" of several Decepticon-analogues running around. Do not think about this too much, you'll only hurt yourself.
The Bad Piggies have taken on the traits of Decepticons from various realities. Sometimes these Deceptihogs are pretty direct analogues, sometimes they're "mashups" of multiple disparate incarnations.
On top of that, there are several smaller robo-buddies who have joined the team who look to be purely Cybertronian, and may in fact be the real deals.
