I remember those! Shooting those discs was great fun. I had all the original ones, even the funky car and dragonfly ones. The black Jet one was more of a badass than most of the Bionicles they've released, some original Toa aside. I always thought Bionicle Pohatu reminded me of the Throwbot Torch. I'd push the lizard one's head in and out until both picks flung off and got lost. Goooood times.
I was nuts about slizers/throwbots and roboriders. I collected all of them, so by the time Bionicle came along, I had lost interest. The dude on the right is FREAKY (Actually freaker than the rest :-D)
