The Gentle Giant

The big boi to end all big bois.

The one who is large in stature and easily frightens those who are smaller than them. The Gentle Giant may be isolated from everyone else because of how much they scare the others. As big things tend to be stronger than little things, the Gentle Giant may also be the Strongling, which tends to be another reason why people stay away from them. If the Gentle Giant is an antagonist, they'll likely be a Flimsy Goliath, a large enemy who is afraid of fighting others despite having the strength to do so with ease.

Compare to the Casper. The two are both harmless yet intimidating figures that may feel lonely because of how terribly so many people seem to fear them. They can also be befriended by the Main, maybe out of pity.
