Saints Row IV

GTA 's surrealist third cousin (twice removed) gets even crazier and subsumes some Prototype into their DNA.

Unused Homies
These NPC were set up to some extent to be summoned via the phone as allies. Many of them are marked as "MaybeDLC" in the data. rsion.

Lin
One of the lieutenants in the original game, Lin has no voiceover during gameplay but there are a number of unused audiologs and text pointing to an unused mission where she got revenge on William Sharp.

William Sharp
The evil attorney has no voiceover during gameplay. His model was repurposed for the senator that you punch out during the start of The Saints Wing. There's also a version of him that's hostile and armed with an alien weapon, so presumably he would have been the boss of a Lin/Donny loyalty mission before being reconstructed as an ally.

Viola DeWynter
Your former foe-turned-head of the federal reserve uses the same model as in Saints Row The Third, and is fully voiced with new idle dialogue and additional lines for Saints Row IV-centric stuff like UFOs. She also has three unused audiologs.

Dane Vogel
The head of Ultor is present in some form, but can crash the game.

NyteBlade
Not marked as possible DLC, presumably a Saints Row The Third leftover. More or less the same as he was in that game.

Super Saints Backup
Not marked as possible DLC, summons the default Saints Row 1 and 2 players as they appeared in A Game Of Clones.

Phillipe Loren
While you fight Loren at the end of Gat's loyalty mission, you never earn the ability to summon him despite him being fully set up and voiced (including "answering the phone" lines) for doing so.

Regional Differences
Due to the usage of Alien Drugs for positive gains, the Australian version disables Shaundi's Loyalty mission – the moment it unlocks, it's automatically marked as completed and you're awarded the benefits as if you'd completed it.
