Yazan Gable

Yazan Gable is a character from Mobile Suit Zeta Gundam & Mobile Suit Gundam ZZ and is a minor antagonist in Knights of the Multiverse Season 2. He returned along with a sizeable amount of former Titans as part of the Titans Remnants and as a pilot for their Providence Gundam, which he gladly accepted to get his revenge on the Zeta Gundam (and for his own amusement, of course).

Personality
To put it plainly, Yazan is a monster, with a soul that is as black and ugly as his outward appearance would suggest. He will stamp down on the feelings of others because that's simply what he does. It's what compels him.

At the same time though, he became very irratic when the Zeta activated its Bio-Sensor sprung from how invincible he saw it was during the battle at Gryps.

Relationships
Due to his violent tendencies, Yazan doesn't form any "friendships", per say. Rather, he simply makes deals with people in power who can help quench his bloodlust.

The Knights
Yazan only sees the Knights as a bunch of kids playing superhero, and are just more easy targets for him.

Kamille Bidan
Yazan's revenge against the Zeta's pilot isn't so much out of any personal feelings, more so just about him finishing the job he started at Gryps.
