Toys from your childhood.

I also loved playing doctor Frankenstein and creating new heroes from the parts of broken ones.

Lol, I did that too.

I had a lot of Spider-Men, all sorts of them. And in general, there were many characters from that cartoon: Scorpion, Venom, Carnage, Lizard, a six-armed spider-monster, someone from the goblins, and maybe someone else, I don't remember anymore. Besides that, there were three Spider-Men in different outfits, one on a skateboard, the second on a scooter, and the third on a snowboard. There was a Spider-Man on a motorcycle, and you could shoot plastic projectiles from it. From the X-Men, there was Wolverine and Cyclops, but from the movie, and I really wanted ones like in the cartoon; sometimes, after the end of an episode, they would show them, but I didn't see them in stores. There were also figures from the cartoon "The Mummy." They did something there, and armor appeared on them; the toys also had it, and you could put it on and take it off. The guy with wings was the coolest.
There was also a series of toys with some kind of poachers or something else. They had cages, nets, and various devices for catching animals. I collected them all, and I also had many animals from that set. I remember seeing their helicopter and an elephant in the store. Oh, how I wanted that helicopter and elephant! But it was expensive, so I never got them.
I still have Godzilla. It's the oldest of all my toys. They bought it for me when I was three years old.

I had many different cars, including remote-controlled ones. Two race tracks.

All sorts of weapons. Rifles, pistols, shotguns. I remember a double-barreled shotgun and a Uzi. There were bows, swords, and a cool crossbow that was easy to use and shot far.

Among the toy soldiers, there was US and Japanese infantry, several tanks, and airplanes. There were also Indians and cowboys, some Barbarians, and Vikings.

Among the plush toys, my favorite was the Pink Panther from the cartoon. There were all the animals from the Chinese zodiac (I set myself the goal of collecting them as a child, and I did), and many other things.

I didn't have many construction sets. I had some small set of parts, and I used it to build a spaceship, imagining that I was traveling through the galaxy on it. But my friend had two large bags of plastic construction blocks. And when I came to visit her, we built large castles and fortresses. She also had many dinosaur figures, and we loved to play with them.
