ok, by a minor act of elimination ... my vote is for General Kommenus, not sure he's been descibed as tubby...
I'm pretty sure it's Akakide who's described as fatter than the attacker, not the other way round. Tufto's evasive response makes me think I'm looking in the wrong place, so now I'm doubting it's Komnenos. I'll have to wait and see.
