I love the original Marvel run of the comics. The issues towards the end felt forced, and any time they had to do an issue to introduce a new toy was always a little awkward, but over all the entire series is brilliant. I have all of the original run, spent a couple years sourcing a few issue I missed, mostly from the Special Missions series. I also bought the Trade Paperback editions years ago.

I enjoyed the cartoon and all of its goofiness, but the comic books felt more grounded.
