I have noticed that overall, online information on MOTU is considerably less developed than Transformers. The He-man.org Encyclopedia is very 80s centric with most other eras incomplete or as placeholders. The Grayskull wiki is much better but is still lacking in information.
The thing about the 2000 series is that overall, all the characters are very similar if not identical in concept to their 80s counterparts with some exceptions such as the Snake Men and The Horde. Of course the series is modernized so much of the 80s cheese is is removed (not all) but the spirit of the original is still there and the series actually develops characters that were never touched upon or neglected in the 80s cartoon.
