Hobgoblins in Destiny have only one tail while the ones in Destiny 2 have two.

Those won't appear on maps, because they don't trade with the good races(or probably anyone), so it will be up to the DM to create these areas. But they definitely will have fortified outposts and controlled areas in the wilderness.

Shooting a Hobgoblin with a sidearm will prevent it from using its stasis ability. I don't see Hobgoblin tribes warring with each other because they have too many enemies as it is (the good races).

Two empty Hobgoblin chassis can be found inside the Tower alongside a collection of Cabal and Fallen weaponry.

Players can abruptly change their movement direction when hearing a Hobgoblin fire to avoid being hit. Unlike some other long-range enemies, such as Adherents and Cabal Headhunter-equipped Psions, Hobgoblins will lead their shots based on the movement of their target when they fire their weapon, making it slightly harder to dodge their shots. Their shields also restore a significant portion of their health. In Destiny 2, they largely remain the same, save for sporting two tails, and a glow that signifies that their shields are charged. These Slap Grenades do Void damage, and the Hobgoblin's Line Rifles do solar damage. Occasionally, Hobgoblins make use of Slap Grenades to force players out of cover and push them back. Guardians who step into this shield are inflicted with the 'Burning' debuff until they withdraw. When attacked, Hobgoblins often seal themselves in stasis within an impenetrable shield that renders them completely immune to all forms of damage. They are also more armored, sporting a second shoulder plate. Nessus-born Hobgoblins maintain an orange glow that signifies a charged shield.

They have distinctive tails and are often armed with weapons called Line Rifles, terminals which theoretically draw energy from the accretion disks of galactic singularities. Hobgoblins are hardened Vex units fitted with improved optics and acute sensors in their horns.
