First off I am new here. Not new to collection vintage “toys”. I have a very, very,extensive sw collection. TF was just on the periphery of my toys as I grew up. I watched the shows and read the comics but joe and sw were the toys I collected as a youth. My son (4) has started to show interest in tf. We watch g1 episodes and some of the prime series on Netflix (or Hulu or amazon, can’t keep track of all of them). I’d like to get him some core characters but these lines are pretty confusing and complicated for an old guy like me. Where do I start? Any suggestions? Thanks in advance for your help and suggestions.
