Half-Giant
Half-Giants are a race in the Dungeons & Dragons setting of Dark Sun. They are magical fusions of humans and the now all-but-extinct giants, creating a race that fills the missing half-orc niche of "Big, Strong, Dumb Bruiser Race".
Half-Giants are remembered fondly for their stupidly high potential Strength and Constitution. They are remembered less fondly for their extremely high supplies requirements, and even less so for their mandated Chaotic Stupid racial fluff. Long story short, half-giants as a species suffer a really bad form of ADHD combined with multiple-personality disorder, causing them to reinvent their personalities based on whoever's around them at random intervals, possibly each day.
This fluff was considered so annoying that WoTC chose to dump it entirely in the 4th edition revival of the race, as well as mechanically reducing them to just reskins of the Goliaths, who were already designed to be giant-like huge, strong, tough humanoids.
