- Ass Pull: Optimus coming back to life comes the heck out of nowhere.
- Author's Saving Throw: This series gives us the first on-screen combination sequence in the form of Volcanicus' introduction after the previous two series avoiding showing combiners actually combine like the plague.
- Megatronus accidentally killing Solus Prime and mourning her death is sad. Solus Prime showing no damage at all from a blast that was visible from space and wrecked the entire room they were both in, and somehow still dying from her not-visible wounds, is hilarious.
- When Overlord kills Menasor, he doesn't seem to put much force into the killing blow, causing some to liken the attack to an aggressive back rub.
- There are several instances where Grimlock doesn't transform into robot mode during fight scenes and instead chooses to wrestle his enemies using his tiny t-rex arms. It's much funnier than it sounds.
- They Wasted a Perfectly Good Character: Volcanicus. After fighting our heroes in the swamp, only Grimlock joins the team and the combiner is never formed again. This could extend to the other Dinobots too.
- They Wasted a Perfectly Good Plot: While we do get to see an actual combination sequence, the only aspect introduced by the toyline that is incorporated here is the Leader class Evolution gimmick. Prime Masters and the powers they grant are completely absent.
- WTH, Casting Agency?: Some fans are not amused to the fact that Ron Perlman voiced Primal instead of Gary Chalk. Ironically, Chalk himself was actually interested in seeing what Perlman would do with the role.
