1999?
No, it was 2001-2002

kai joined the bladebreakers in the origional beyblade series then ditched them then joined them thend ditched them then joined them and thar happened every 4 or 6 episodes. the best thing about this show was collecting the beyblade i had at least 150 of them that includes the RC beyblades, knock off beyblades, standerd beyblades (mostly imported from canada) and heavy metal system blades.

I found it a lot funner collecting and battleing with beyblades more then the actual show.

Man this show was off tap for a year when i was in gade 4 or 5.
I dnt think we got this show until like 2000 or 01 maybe evn 02 in Australia.
I liked collecting the beyblades more than the actual show.

I only watched the first few episodes when it aired. The American intro music was insane.

I loved the first and second season. I kinda lost it now. Kai and Rei rocked!
