Top 5 Best Transformers Prime Characters
Transformers Prime was, to me, an amazing reinterpretation of the G1 story and characters for a new era. The animation was top notch and the voice work was out of this world, teaming up industry veterans, newcomers and huge stars (the first voice you hear is The Rock's). It also featured a great cast of classic Transformers characters which payed great homage to their original selves while expanding on the personalities laid down in the G1 era. Let me explain exactly what I just meant by that by starting this list of best Prime characters with...
5. Starscream
This was classic G1 Starscream but now with a sleeker body to compliment his very narcissistic personality. Of all the character on this show, he was probably the one with the least of an update to his G1 personality which gave a nice comforting sense to the series, while letting his more maniacal traits run free (ie: MURDER). Of all characters, he has by far the best introduction.

4. Dreadwing
An honourable warrior, very similar to the Dinobot character from Beast Wars and though it was less original at this point in the franchise, it was still a great role. He was smarter than most other decepticons and didn’t follow the cause blindly. The character was elevated even more with the Candyman himself (Tony Todd) giving Dreadwing a very deep and authoritative voice. It complimented this badass character perfectly.

3. Arcee
I really love how the greatest warrior the autobots had (this side of Optimus) was their smallest member. It gave a nice contrast to the role usually given to her body type. She even had that great 80s staple of the cop who had just too many partners die on him (her) and they made it work. It was great to see her balance out her anger with a softer side that she thought was probably lost.

2. Megatron
This is the best version of the Decepticon character we've ever had on a show and the second best character to own the name (yessss). I love how he had this twisted sense of ideals and his unquenshable thirst for power was a beauty to behold. I also loved how cunning (his genius plan to be able to use the Forge of Solus Prime) and ruthless (his fight against Predaking) this version of the character was. A true warrior who was fearless and would do whatever it took.

1. Soundwave
Soundwave was always awesome in G1. He was the guy who got stuff done and would never b!tch about anything. This is taken to the extreme here with an almost entirely silent role. This gives him an added creepiness factor that had never been shown to this extreme before. His loyalty to the Decepticon cause was also frightening. Calm, calculating, intelligent. As the show progresses, it becomes more and more clear that he was the Decepticon’s greatest asset in their fight vs the Autobots. Of all Decepticons, he was the one you’d want to mess with the least.

Honourable mentions: Knockout, what a fun character! The show also had an interesting take on Ultra Magnus and Wheeljack.
