Muscle tone is worthless against raw mass. Always bet on the fatty.
Blaire just needs to keep him from getting too close, circle strafe and spam him with hits from her Unicorn Rising branded Melee Machete and her pink Glock 17 while avoiding cane hits and clubbing blows from his fat ogre hands and then do a coup de grace with an explosively formed penetrator from the lipstick sized Mini LadyEFP in her handbag once his hit bar is low enough.
It's a standard boss fight basically. Maybe she'll have got herself a couple of LadyEFPs. Or, even better. the non mini version of the LadyEFP which is the diameter of a makeup mirror and features a laser diode for sighting. Yaniv would be a one shot kill to that, even if he commandeered an armoured vehicle before the battle.
