I've been wondering if there has ever been evidence of transformers dieing of old age or natural causes. I cannot remeber anyone dieing who wasn't killed somehow and that bothers me. I can accept that they live for millions of years and can replace damaged parts and even upgrade themselves in some cases. I'm okay with the idea that they can survive in stasis for untold years and remain mostly unchanged. I like that we've seen things like cosmic rust and cybertronium depletion represent how disease might manifest in robotic or cybertronic life. I like that the hate plauge could effect both TF's and humans because it helped to show how the two races are similar on some level. Transformers have been poisoned by tainted fuel and were in pain because of it. There are even some injuries so sever that they cannot be repaired as is the case with Rack'n'Ruin. But how do transformers die if not by conventional weapons? Shouldn't their sparks (or whatever you want to call them) burn out eventually? I've always considered death to be a natural part of the life cycle along with eating, growing and reproducing. And all of these things have been represented in diffrent ways in various media. But to not see an end to the life cycle mirrored somehow in transformers makes them less interesting to me.
