Who was the so call fat man in judges chapter 4 or 5?

In Judges chapters 4 and 5, the "fat man" refers to Eglon, the king of Moab. He is described as grossly overweight, which plays a significant role in his demise. Ehud, a left-handed Israelite, assassinates Eglon by cleverly concealing a dagger and fatally wounding him in a private audience. This act leads to the Israelites' victory over the Moabites.
