Changed it to top 5 things because that's how I roll. Don't forget to put on your Nostaligia Goggles before reading the list!
1. Dragonball Z
2. Harry Potter
My first real book series. I got hooked on Harry Potter in 4th grade, when my mom recommended I read the books; I listened to the first one on tape and quickly went through the next three, and from then on I was an absolute Potter fan. Waiting for the books to come out every summer and basically growing up with Harry was one of the biggest parts of my childhood. When the last book came out, I actually had to stop reading it part way through because I was crying; knowing that such an integral part of my life was about to end was too emotional. Kids today with their ipods and their Twilights don't know what it was like to grow up during Pottermania.
BABIES FIRST COMIC. But seriously, my first real adult comic, one with plot and feeling and symbolism and so, so much that it remains, to this day, one of my favorite pieces of literature, ever. Oh, and I totally cried when Rorschach died.And Ozymandias remains one of the best villains of all time. "I did it 35 minutes ago," indeed.
4. Ranma 1/2
My first real mango! I loved the martial arts and the comedy (still do), and Shampoo was my first waifu. I re-read the series recently, and it still holds up well; funny, engaging, and it has heart. Definitely one of my favorite manga of all time.
5. Pokemon Red
My first real video game. My brother got Blue, I got Red, and for both of us, there was no turning back. We played our Gameboy Colors non-stop; even in the back of the car at night, we would wait for Mom to drive past a lightpole for a glimpse of the screen. Bulbasaur, man, you were a great starter, and a true bro. And Gary, fuck you, you were the biggest dick of a rival ever. I will never rage as hard as I did when I was trying to find a Pokemon Center, one Pokemon left with barely any health, and Gary rolls on up and challenges me to a battle.
