When my kid-ears first heard of Bionicle (G1 2001), I got my mom to buy me an Onua. I later added on Tahu and Lewa, I think. Then I got a few Rahi -- Muaka/Kane-Ra, Tarakava, and Manas. Probably bought like 20 of those old mask packs.
I got a few Bohrok, Va, an Exo-Toa, and the Boxor in 02. I became annoyed with clone sets around the time the Bohrok-Kal came out and slowed down my collecting. Got some Rahkshi, I think. The only sets I bought after that were Vakama Metru and a Metru Matoran.
Then I took a decade+ break from Bionicle. When G2 came out, I started getting back into the lore (man, I missed a lot in that department ). At the moment, I'm trying to re-buy the 01 line (with boxes and instructions) since I sold all my old ones. So, if anyone wants to sell me some Rahi that match that criteria, let me know! Already re-bought the Toa and Turaga.
