Continuity: When Daniel finds Spike inside Unicron, the control panel he uses to convert his arms to blaster mode is already open and 'active'. Seconds later Daniel opens and then activates the panel even though it was already open to begin with.

Continuity: When Perceptor is looking for somewhere to land the shuttle he and the others are in, the square on his head goes from black on the outside and yellow on the inside, to fully yellow, all in one shot.

Continuity: During the fight scene between Optimus Prime and Megatron at Autobot City, Megatron pleads for mercy. He reches for a gun that is under some metal. The gun is black in colour. Then Hot Rod jumps on him, Megatron stands up and the gun is now purple. It then goes to a close up of Megatron with the gun in one hand, and Hot Rod in the other, and the gun is now black again.

Other: When Perceptor pops up to tell Blaster to radio Prime, Blaster acknowledges that Perceptor is there before he even sees him. And I doubt he could of heard Perceptor because of the amount of noise the lasers were making, and Perceptor didn't make any noise.
