Soul Edge, later
known as Inferno, is the
physical manifestation of the cursed sword Soul Edge's own soul. It fights using
the attack style of other fighters from its memories of past battles, and will
switch to a random one at the start of each round. Though it exists in its own
dimension, Chaos, it has used duplicity such as in the case of tricking Siegfried
into expanding its will, and in more extreme cases utilized Cervantes'
flaming corpse and later the remnants of Nightmare's
armor to create an avatar for itself. Its will and power has directly and
indirectly affected several other characters in the series, such as the Evil
Seed event that caused many to turn somewhat evil or insane. It has also
caused the creation of several life forms or modification of them, such as Ivy's
sword, Charade, Necrid
and Abyss. As Soul Edge, it appeared
in Namco X Capcom, shown to have the abilities to create Charades at
will, as well as teleport its evil body.
