Since people seem to be “new” here with regards to Dizzy’s backstory, I’ll first say this.

To understand Dizzy’s past, you have to understand the connection Gear research had on her past.  Illegal Gear experimentation conducted largely by the Conclave and the Postwar Administration Bureau.

The Bureau are by no means the only organization that tried to create their own “version” of Justice (whether that be a Robot Copy, Forbidden Beast Gear-derivatives like Eddie and Angra, imperfected Gear conversions like Testament, and other derivative bioweapons like Tyr)… other groups like Blackard Company also created their own “Justice” Gears like Solaria and Marina (a failed attempt).

The most notable connection to Dizzy is Eddie.  Or as Testament refers to him “A Ghost from the Crusades”.

Eddie is just one of many “Kinjuu” (Forbidden Beasts) that were created during the Great War as a means of subjugating Justice and her Gear Army.  Kinjuu literally worked alongside the Sacred Order of Holy Knights in the background as an “alternative means” of fighting off the Gears (Kliff knew of them, Ky was kept unaware at the time until he met Tyr by coincidence).

Unlike normal Gears created “after” Justice in the manifacturing process, Kinjuu are parasites born “without a body” inside a human host.

Because they’re born inside that human host, they have a natural immunity towards Justice’ Command Type ability to control other Gears.  This ability was VITAL as all previous attempts to create Gears that could resist Justice’ influence ended in FAILURE (Testament was one of those failures, as he ultimately fell under Justice’ power to control his mind and will).

Kinjuu (during the Crusades) were programmed with a limited life-span so as to be used as “disposable weapons” and were “programmed” to hunt Gears.

In other words, Gears and Kinjuu were “natural enemies” during the Crusades.

But just like Kinjuu are programmed to hunt Gears, Gears themselves have a “diagnostic combat defense program” that was installed in them as a way to evolve as they fight as living weapons.  All Gears, with very few exceptions, have this ability installed in their subconsciousness.

In Dizzy’s case, that “defense program system” is manifested as Necro and Undine, who act to protect Dizzy when she is threatened.  Necro in particular has taken over Dizzy’s consciousness in dire situations in the past (especially when I-No attacked Dizzy), and Sol had to use his powers to subdue Necro in order for Dizzy’s “real self” to resurface.

Back in the year 2181, Eddie (having taken over Zato=ONE’s body) was on the run from the Assassins and came across Dizzy in an altercation that spurred him to fight her for what was seemingly no apparent reason.

That confrontation allowed Eddie to become more “self aware” of his identity as a living weapon, though it would not be long before Eddie and Zato both died afterwards.

At the same time, it revealed that Dizzy herself was resisting the “influences” of her manufactured past.  This would all come to a head when Dizzy confronted a Justice Copy created by Crow Kuruwaba a few weeks later.  

It was thanks in part to Sol’s influence and teaching that Dizzy was able to resist the Justice Copy’s control.

Suffice to say that, despite the fact Dizzy has no “immediate” connection to the Crusades (she was born after 2175 when the War originally “ended”), her past “artificial memories” of that time were all based on the memories of Justice, which she found so “nostalgic”.

Dizzy is self-aware of this, so when she fights, she “fights against herself”… the self that is a COPY of Justice, a “killing machine”… the self that isn’t “Dizzy herself”.
