It's 10x better than DBZ, the plot does sound GITS-ish but no, and I have no idea what Trigun is... as stated before, refer to the wiki on the link over there...
And you should really watch Needless by the way, it's amazing... and has tons [and TONS] of fanservice XD
I hadn't heard of Needless before. Is it good?
Wait, no, I doubt you'd be starting an RP for it if you didn't think it was good. How abut this; does it seem more like Dragon Ball Z, Ghost in the Shell, or Trigun?
