One of the biggest debates begun by an animation error is IMO the "who is Cyclonus" debate. 1) Fans agree that there are at least 3 sweeps + Scourge, totalling 4, although only 3 Scourge/sweep bodies were shown being created 2) Fans agree that there is really only one Cyclonus, although 2 were pictured as both Skywarp and Bombshell became Cyclonus. The "Cyclonus and his armada" line was supposed to be left out of the movie. So there was really only meant to be one Cyclonus. In conclusion, Either Skywarp or Bombshell were meant to a fourth Scourge body. My money's on Skywarp being Cyclonus because I figure Unicron would have sensed that Skywarp was a trusted member of Megatron's inner circle... but that's just my opinion. Any other debates caused by animation errors?
