I remember the first time I played Silver version, I decided to use all the Pokemon which were rare for only one in the game; all except Legendaries, of course. I had Typhlosion (of course), Togetic, Espeon, Sudowoodo, the Red Gyarados, and I believe that was it. The Red Gyarados didn't phase me with "how I was going to catch it?", but rather how hard it hit! So the first time I got to that point, I was so scared it might kill my team, I killed it! Luckily I saved before...so I got it at the second try. He's a very strong pokemon!
