I was never too keen on the hollow triangular prism shape of the Sathanas' HTL beams, to be honest. Seems like a bit of artistic license was taken over the original solid red spikes. Granted, those were probably only spiky in the first place because of poly limits of the time, and we can afford a lot more detail now. But as a counterpoint, the Ravana's beams still look pretty much the same: big ol' red spikes of doom.
Why does the Sathanas get these fancy beam emitter models when the Ravana continues to use sharp pointy spikes (which also look a bit more intimidating, IMO)?
