Failurebot is an NPC from Borderlands 3. It is first encountered during the Rumble in the Jungle optional mission.
Background
Failurebot is a friendly bot found in the Science Outpost. Being abandoned and locked up in a shed by a research team, it is guilt-ridden and has very low self-esteem. Failurebot is not its original name, but scientists hard-recoded its identity chip after figuring out it is "dumb and bad and undeserving of love."
