The following designations are made in regards to heroes:
- Confirmed: Heroes that are either present in the game, or confirmed for inclusion at a later date. They are sorted by class—those under the heading of "unknown" are confirmed for inclusion at a later date, but are of unknown class.
- Proposed: Heroes that have been acknowledged by Blizzard Entertainment as candidates for inclusion. This is not a category for rumors or for users to submit their own ideas, but rather, to log possibilities as described by Blizzard, and Blizzard only.
- Data-only: Some data exists for heroes within the code of Heroes of the Storm. Such data should not be taken as confirmation of inclusion, or as a proposed hero (though can be considered as proposed if Blizzard acknowledges the possibility of their inclusion).
- Removed: These headings list heroes that were at any point confirmed for inclusion (i.e. having an actual presence in the game, or with explicit intent of being included), but were removed. Note that a removed hero may be listed under "proposed," but only if there is an indication from Blizzard that there is the possibility of them returning. Data-only heroes do not fall into this category through absence alone, and any actual removal must be confirmed.
- Cain (proposed hero, given NPC status in Eternal Conflict event)
- Malthael (considered, role taken by Leoric)
- Tracer (Release date: April 19, 2016)
- Lúcio (NYI)
- Zarya (Release date: September 27, 2016)
- Duke (replaced by Sergeant Hammer)
- Grunty (became a variant skin for Murky)
- Hybrid Protoss
- Kerrigan (as a ghost, became a color variant for Nova)
- L80ETC (replaced by Elite Tauren Chieftain)
- Leon (absent from current builds)
- Ultimaton (absent from current builds)
- Vaevictis (absent from current builds)
- Warfield (replaced by Sergeant Hammer)
There is, and will be, more heroes from the Warcraft setting than other Blizzard settings due to the size of the Warcraft universe. However, the developers intend to try to split the hero roster along Blizzard's major universes.
- Brann (Warcraft)
- Cenarius (Warcraft)
- Sapper (Warcraft)
- Shandris (Warcraft)
- Varimathras (Warcraft)
- Deathwing (once proposed, confirmed to not be included)
- Onyxia (possibly a creep rather than a hero)
- Shaman Thrall (originally a separate concept, has since been made a skin variant)
- Za'Muro (effectively replaced by Samuro)
Kaeo Milker has stated that the team believes that they will bring in heroes from other Blizzard intellectual properties aside from the Diablo, StarCraft, and Warcraft settings. This includes original heroes that are inspired from the Nexus directly.
