Here's why the confusion might exist:
* Similar Design: Barricade and Sideswipe share some visual similarities in their vehicle modes. Both are Chevrolet police cars, and they have a similar, aggressive design.
* Different Characters: Barricade and Sideswipe are distinct characters with separate personalities and abilities.
* Deception vs. Autobot: Barricade is a Decepticon, while Sideswipe is an Autobot.
So, while they might look similar, they are not the same character. They are both unique Transformers with their own roles in the story.
