I know what you're thinking, Malice is Chrono.
And you'd be correct, kind of. Malice is an entity residing within a mask.
The mask itself is said to change the persona of whoever wears it, it induces a state of 'apoplexy' which varies from person to person. This is due to the unique chemicals found in a dormant bacteria that resides within the metal of the mask from an ancient tribe.

While the Mask has been broken during various times, it always comes back together eventually, like new.
The broken pieces also affect individuals in a certain way.

This 'thread' is mainly designed to show those who have adorned the Mask of Malice


Chrono
While Chrono is the first noted wearer of the mask, he is not actually the first person to wear the mask.
Malice in this sense manipulated the emotions of Vanity, Lust, Power, and Knowledge


Phoenixfire
After the epic Landry v Malice feud, Phoenixfire got ahold of the mask after pushing Chrono off a stage into electrical equipment.
Athena became 'Dark' Phoenixfire, as her inner turmoil was unleashed
Malice in this sense manipulated the emotions of Fear and Revenge


Lily Attwood
In a comedic segment, Lily Attwood adorning a piece of the Malice mask did the absolutely most evilest thing anyone could ever do, ever.
Drink milk directly from the carton and put it back into the fridge.

Yukari
Yukari only had a quarter of the mask, it didn't affect her as much as everyone else, and only seemed to heighten her sense of aggression.

Karen Attwood
Karen has a piece of the mask. It was never used by Karen. More than likely she doesn't have it anymore.

Eras Clepsydra
Eras managed to get all the pieces of the "Broken' Malice mask, and she did rebuild it. It's currently unknown if she 'did' wear it at one point
But she no longer has the mask.

Kurone Clepsydra
Kurone at one point or another has adorned the Malice mask, if only to get accustomed to the manipulative nature of the mask...
Or even on the basis of her own mask Scorn (and future masks)

Nina Royale
Nina more than likely has adorned the Malice mask at one point or another, if only because her Mask (Menace) is the original mask and Malice was the basis of it.
She is more than likely the first canon wearer of the Malice mask.
