Ty! Let's go with potentially the scariest option: dark side Galla.
I think it would take a lot for her to go 'full dark' as it were, she has a lot of mental and emotional fortitude. But I could see it happening if she had been the only survivor of her original Warband and operated outside of the Pact. She wouldn't have accepted being a Gladium so she would have gone full solo - gradually letting her anger win.
If Galla went dark side, Jesus wept. She is already so intimidating and scary - with anger issues. The other version of her would just be a destroying and almost feral machine with her amount of bloodlust. All of her discipline would go out of the window and she's almost be a rampaging rabid killing machine.
Even sane Galla killed someone in the sparing pit back in her pit fighting days by just not stopping. Strangling and punching another Charr until their face was beyond recognition and needed 4 guards to get her off the body.
That is sort of the thing you are going to see as the norm for her - her damned merciless tenacity. She would go after anyone who used elemental magic or magic as a whole. She would go after people who tried to stop her and people who got in her way. People at the wrong place, wrong time, and anyone who she deemed a problem.
It's tragic because regular Galla has worked hard and succeeded in handling her anger issues, she's done the work. She's also refined her mind and finds contentment studying strategy and coming up with battle plans instead of being in the grit which brings out the frenzy. The Wall of Charr has done the work! She's got a firm handle on her bloodlust!
But all of that would be wasted in dark Galla, and only her pure primal fury would have control. I could see her being a Raid Boss or something of that caliber.
