Dual elfin can't combine with other bakugan , but elfin can combine with klawgor and scrapper.
The G-Power Changing Elfin, Special Attack, is the one that changes G-Power. Not Dual Elfin.
dual elfin aquos highest g power is 650 then 610 then 550
I don't know but I did found it on Friday 15th may 09 it wasent a elfin it was a dual elfin mine is an aquos 690g's really strong
i think it does bacause dual elfin doesnt have the wheel and preyas does
