Continuity mistake: In Season 2 Episode 22, Model Behavior, Woody has gotten his braces off. However, in this episode, he has braces back on again.
Other mistake: The battle droids - including the commando droids featured here - habitually have two broad fingers and a thumb. So how can a commando droid squeeze itself completely into clone trooper armor without its broad fingers tearing open the gloves, since it can't separate its fingers?
Triumvirate of Terror! - S3-E8
Continuity mistake: After revealing himself to Wonder Woman, Joker rips of his cross-dress disguise. The two halves land on the ground on both sides of him.

Iron Forged in Fire: Part One - S1-E1
Continuity mistake: Trish interrupts Tony and Obadiah’s conversation to tell him that his next appointment is here. Obadiah Stane then stands up from his chair and begins to walk.

Continuity mistake: At the beginning of the episode, Storm and Professor X can be seen on the asphalt between the grass and the mansion, behind and to the viewer's left of two boys. When the shot changes, they are suddenly on the grass and in front of the two boys. (00:00:50)
