Background
Corpo, born of the Illip kajidic to Gardulla Illip Alto, was discovered as force sensitive at a young age, barely a huttlet, and was turned over to the Jedi Temple at Coruscant a scant decade later, no older than 50 years of age.
Hutts age slowly, and for much of their life, learn even slower. Corpo saw many other younglings come and go during his time at the temple, and became a fond fixture of the youngling Thranta Clan.
As for how he cycled out of there, that depends entirely on the era in which a game takes place, but either way, he looks older than he is by Hutt standards, although you would not know it by his demeanor - a demeanor earned by many years of being the oldest in the company of children.
Motivation
• Growth, Community:
While many Consulars take a macro view of the galaxy, just as many find that perspective far too detached from the beings who inhabit it. Corpo focuses on community, and thinks small, believing that peace and balance is a natural result of community members growing together, and engaging with the lives of their neighbors.
Morality
• Emotional Strength - Fondness:
Corpo has a kind of mentorly love; a gentle and kindly affection for a friend, student, or group, wanting to guide, help, and advise them in general. He genuinely wishes people to grow, change, and surpass his teachings, and this unwavering dedication is an inspiration to those around him.
• Emotional Strength - Patience:
Corpo faces delay and obstruction with a calm mind, recognizing that in time all things will reveal themselves as the Force wills it. He subsequently keeps a steady mind even in the most frustrating of circumstances.
• Emotional Weakness - Possessiveness:
At times, Corpo's devotion is so strong that he cannot see the subject(s) of his fondness turn to others, which can lead to envy as well as turn protectiveness into imperiousness. This risks treating people as smaller than they are, less than even a pet, requiring constant control.
• Emotional Weakness - Condescension:
Corpo often treat less patient beings like children - whether they are children or not - and act dismissive of their concerns. As a result, he has a tendency to overlook (or even outright ignore) valuable insight from friends and allies. Not because he is particularly prideful or arrogant, but because he pays no mind to their impatience, even when it may be warranted.
Description
As great and unshapely as any Hutt, most would not be able to tell Corpo from any other of his corpulent breed, save perhaps for his uncommonly blue eyes, wide as saucers and deep as the wells of Alderaan.
To other Hutts, however, it is readily apparent that Corpo is younger than his demeanor may sugget, and in good condition compared to most of their kind, suggesting a potential threat that should not be underestimated.
