I grew up in the 90's, so my favorite stuff were the Batman, Godzilla and Power Ranger action figures.
I loved those things, especially this awesome giant transforming toy I had of the white tiger from Power Rangers.
Those were the coolest toys you could get back then.
I also loved certain Sailor Moon toys I had. I was able to save one of a heart locket that plays music and lights up when you open it, still works. I think the Sailor Moon toys were the only girly toys I liked as a kid, everything else was action figures, water guns and nerf. I always wanted a BB gun, but my dad wouldn't allow it.
Still like action figures though, I currently have 19 action figures on my computer desk alone, and more scattered throughout my room.
