That have sense, I liked Kanden a lot because I should choose sniper like characters in games. And Weavel call my attention in some trailer spliting in two. Later knowing he was a pirate, that made me like him more.
I always loved how the Space Pirates make anything to survive, change and overcome anything, specially Samus. How they change game to game have sense out of the usual change that the developers have/want to do. Then we see them in Super Metroid changing color because in that time it was the norm to show the strength of the enemies, to the changes we see in them in Prime series, more metalic in P1, or shadowy in and twisted in P2 because the developers can and are willing to do some big changes to them but leaving the feeling that, even with the years apart, they are still the same ferocious creatures.
The same feeling I have with the Xenomorph of Alien franchise. Maybe the movies are good or bad, but that little bastards are really a threat, and have a lot of forms, depends on the species in wich they incubate, but still, they are the Xenomorphs.
