Orga is okay, though I really liked him when I was little due to seeing Godzilla 2000 in theaters when I was 7 or 8. To the contrary, he didn't get much screentime, meaning he didn't get to do much.
I did like seeing more of him in the Atari games, especially DAMM. I loved his double-claw uppercut and paralyzing goo, as well as the "flick" animation he had in Unleashed.
While I do like the manga version of G 2000 more than the movie, the incarnation of Orga was... meh.
No teeth and he had these weird vagina things:http://gigan05.deviantart.com/art/Godzi ... -305698875
And in this version Orga's cannon was located in the middle of his shell/hump rather than on his shoulder.
