3 or more Level 7 monsters
You can also Xyz Summon this card by using
any number of "Number C" Xyz Monsters you
control, whose number is between 101 and
107, as the Xyz Material. (Xyz Materials
attached to them also become Xyz Materials
on this card.) This card gains 1000 ATK for
each Xyz Material attached to it. You can
target 1 "Number" monster in your
Graveyard; this card’s name becomes that
monster’s, and it gains that monster’s
original effect. These effects last until your
opponent's End Phase. You can only use this
effect of "CXyz Barian" once per turn.
