I love the Alien Races appendix in Marvel Universe Deluxe. All those aliens in black trunks... hehehe. Of course, Rom's species, the Galadorians, look just like humans.The Dire Wraiths, however, really don't.
One of the few aliens represented by a female. And a nude one at that!
Shame about forgetting to include the Galadorians' type of government... Prime Directorship?
