Warm-Blooded, lack of gills, two just popped into my head :D

I also remember reading about a race of Merfolk with lower bodies like seals...

I'm not surprised that you don't see the real problem I have with your posts, lol.

I don't know how the GM feels about it, but [i]my[/i] opinion on it is stated rather eloquently by another player in [url=http://www.roleplayerguild.com/posts/4114222]another thread[/url]:

You are complaining about the fact that you can't have your specific cool Mecha-Trope, no? While others are being allowed their own? Articulated hands, and Transforming Mech. Versus a gun that accelerates a metal projectile to 5 % the speed of light ( Mounted on, and powered by a platform weighing less than 25 tons. Maybe you should consider the different technology implied by what you are asking?

I'm not a scientist, but the technologies implied by articulated robot hands exist today, with no sci-fi magic required, the only difficulty is implementing it properly.
