Companion Companion Fruit
This Paramecia type devils fruit creates a companion to provide a specific service for the user, the moment it is consumed the companion is made and from that moment on the companion is "alive" until the user dies. This companion can be in any form depending on what the needed service is. The companion will continue to get better and better at its service for aslong as the user lives.

Strengths
The companion is immortal for as long as the user lives, this simply means that since he/she/it is the product of a devils fruit then he/she/it wont be able to die since as soon as it would the users DF would just recreate it in its exact form again.
