Code of Hero - S2-E9
Continuity mistake: When the Maximals are disintegrating Dinobot's remains, Rattrap can be seen in his original form when he should be transmetal.
Coming of the Fuzors (2) - S2-E3
Continuity mistake: During the battle at the beginning there is a shot of Tarantulas and Waspinator appearing with Megatron commenting on how reinforcements have arrived implying that they had just got there. The problem is, the previous episode already established them as having arrived before the battle had begun, and they had even been shown fighting before their suppossed "arrival" mid battle.
Chosen answer: Terrorsaur was probably removed because his character was far overshadowed by Tarantulas. Both characters were treacherous and backstabbing towards Megatron, but it wouldn't have made sense to have two characters who served the same purpose, story-wise. Scorponok was removed because they wanted to introduce Quickstrike, and it wouldn't have made sense to have two scorpion characters on the show.
