Companion Card may refer to one of the following:
- The Companion Cards are the only Gears to only have an "Evolved" added to their name upon evolving them.
- They are also the only gears to not change in appearance upon evolution. Only the background of their interface changes.
- They are also the only featured gears in Survivor Mode to gain no additional effects when combined with each other.
- They are also the only gears in the game who have specific effects revolving around a "category" or "group" of characters, as both the Killer Croc and Diablo cards have specific effects for Suicide Squad characters. All other gears with a similar effect have effects exclusive to only one character.
