Orbs are obtained by completing a raid (usually 1 for each completion, for each player). An orb of one of the three types is consumed in addition to Credits and hero shards to increase the star rating of a hero from 5 to 6.
- Stellar Orbs are common. All silver heroes require a Stellar Orb to promote to 6 stars. Some gold heroes (Firestorm, Atlantean Armor Aquaman, Unbreakable Cyborg, Emerald Green Lantern, Horrific Scarecrow, Master Thief Catwoman, Primal Swamp Thing, Multiverse Batwoman) also require a Stellar Orb.
- Cosmic Orbs are uncommon. 10 Stellar Orbs can be traded for 1 Cosmic Orb. Most gold heroes require a Cosmic Orb to promote.
- Galactic Orbs are rare. 5 Cosmic Orbs can be traded for 1 Galatic Orb. Many newer and stronger gold heroes require a Galatic Orb to promote. All Legendary heroes also require Galatic Orbs.
- During the 2 year anniversary event for Injustice 2 Mobile, a free Galactic Orb was sent via messages to all players. However, on social media, an image of the Stellar Orb is incorrectly used.
