“Look out, everybody, things are about to get awesome!”
After Montgomery Jakobs spent most of his ship-building budget on the combat AI GenIVIV, he resorted to purchase a budget Tediore navigation AI to save his remaining funds. This navigation AI was named BALEX, as a result of Montgomery being unable to decide between the names "Barry" and "Alex". Both GenIVIV and BALEX soon took a liking to each other and started a relationship, which soon soured thanks to their frequently clashing personalities. Their acrimonious parting of ways came when BALEX crashed the ship on the surface of Eden-6, and GenIVIV had him installed into the body of a teddy bear before leaving him to the mercies of the local fauna.
BALEX is encountered during the mission The Family Jewel where he guides the Vault Hunters through the derelict ship Family Jewel while arguing with GenIVIV. As a navigation AI, BALEX is later found to be useful to the Crimson Raiders and is installed onboard Sanctuary III.
- Once installed on Sanctuary III, BALEX will occasionally give comments while on board the ship. He will always tell the player not to touch the ship's engine while passing it.
- BALEX will usually ask the character to go to the ship's bridge to squeeze him. His dialogue appears to be bugged, as he will always repeat that he shoved GenIVIV into a hard drive after his initial dialogue ends.
- BALEX is the first character in the Borderlands franchise to use an uncensored version of the word "Fuck"; he does so when warning the character about a Saurian approaching.
- BALEX uses the same model as the plush bear found during Childhood's End. Tannis mentions that it is based off a "Thracian Tetrabear", a species of bear with toxic claws.
