Wow, how can I decide.
I do have short list.
-G1 Iron Hide/Rachaet (just so lame and fragile)
Don't have him anymore as he was broken on the first Transformation (I was 6 and it ruined my Christmas of '84)
-Movie Dreadwing (a gift that kept on sucking)
big heavy arms on tiny ball joints=fail
-Titanium G.I.Joe Megatron (also a gift)
if this was Megs then The war would have been over with in moments. THE WINNER OF THE UBER SUCK!
