Hating each other since birth, Jaynis Kobb and his brother Taylor have never overtly fought one another; opting instead to employ poison, traps, and assassins to do the other in. This has only made them stronger and more clever as they try to outwit and overcome each attempt made by the other on their life.
Eventually, Jaynis was able to wrest control of a town in Rust Commons East while exiling his brother. Taylor has since been plotting to have his brother killed and take control of the town and rename it after himself: Taylortown. He has followers of his own hidden among the population of New Haven such as Erik Franks.
The Vault Hunters assist Taylor Kobb in taking Jaynistown, and in "gratitude" he sends them to a location in New Haven to collect their rewards. However, Taylor's bandits are lying in wait and ambush them, but are all killed. Taylor proves to be an even greater threat to New Haven's safety, so Helena Pierce has the Vault Hunters kill Taylor. Despite adding turrets in the town, Taylor is killed by the Vault Hunters. This in turn reverts his Claptrap back to its original programming to allow the Vault Hunters to enter the Trash Coast.
