Skulking, raving, drooling, lead giants are more akin to rabid beasts than the giants of Garodia. They are known for having been corrupted by the madness of the Underdark. The very air around them radiates insanity.
Psychotic Exiles. It wasn't always this way. In the days of old, the lead giants were just as intelligent as any other giant. However, they were always horribly greedy and power hungry. They were always as tall as cloud giants and lean, but they were well fed and groomed. This would change when they committed the ultimate crime; they declared war against all giant kind, in an attempt to take control of it all. It would backfire, miserably; the combined might of all giant kind from all sides was too much for the lead giants to bear. Although most of the garodians were merciful, the ordning giants were far less so. They slaughtered the lead giants, and the few survivors were forced to flee to the last place left that may have been safe. However, they would soon discover that the Underdark was the last place to seek any sort of asylum.
Beyond Help. As the lead giants stayed in the Underdark, the further into madness they slipped. The lack of food was and still is, a driving force of this insanity. Up above, the giants' poison, which was partially how they got the name "lead", was good enough to catch the pitiful creatures around them. In the Underdark, many creatures lose little from being poisoned, are nimble enough to escape easily, can put up a hard fight, or all of the above. It was either them or fungi and even then it was either dangerous or not even a crumb to them or both. The Underdark is full of vicious predators and villains, like the drow, hook horrors, umber hulks, and duergar, but the ones that were the lead giants' big push into insanity were those that attack the mind. They first encountered the mind flayers, who sought to control them as slaves of war. However much like the kuo-toa before them, the lead giants minds were not prepared for what they had been subjected to and it only worsened when they encountered another beast who sought to do the same thing; the aboleths. At times, both parties ensued their wrath upon the giants at the same time. With the aboleth in the water and the illithid on land, there is little to wonder how they became so mad.
Broken Beasts. With their minds shattered beyond repair, the lead giants have completely forgotten who they were. Gone are the tyrannical masterminds who seek world domination and sought to become gods: now they don't even have a culture, let alone language or religion, and only ever seek their next meal. They have even been known to eat their own siblings after birth. Their insanity has become so bad it is no longer taught, it's now inherited.
