most of my transformers met their doom in a multitude of fashions..
they all were encased in ice at least one.. usually smashed free or see below:
then there was the big ass industrial magnifying lens i had as a kid..(the equivilant of sharks with frickkin laser beams to 10 year old)
these were the original "Battle scarred" transformers
i would burn laser damage gauges in them and occasionally ,if i had the patience and the sun was especially bright, i might have taken a limb for good measure

then there was the month leading up to the fourth of july..
ahh the smell of explosives and melting transformers!
I cant even go into the inhumanities i subjected my transformes to with these incendiary devices.. the most damaged , or no longer deemed worthy were typically sent to big cybertron in the sky with an M-80
boy am i kcking myself in the ass now!
