at one time I had only one beyblade, driger v2. After days of battling my cousin the clips on it broke (the only beyblade means no replacement clips). I know this isn't really a big break but it hurt at the time...
Same thing happened with my friends flash leopard I was using.

And one other time where me my friend and his cousin were battling and both my flash leopard and his cousins dranzer hit the samurai changer and and broke it in half (some part of the plastic inside broke making it unusable). Well thats all i have

well all i have left of my collection is zeus ar, s-ar, wr, bp,
never realy found out what happend to my collection one day it was just gone.
