At an early age, Hannibal became interested in military theory and studied diligently for a commission to the Galactic Military Academy. When he turned 21, he was given a scholarship to attend the Academy, and was later to be trained as an officer. Whilst at the Academy, he excelled in everything that he did. He was sent to officer school early and still holds the record for being one of the youngest officer graduates. Hannibal, as expected, rose through the ranks with ease. Hannibal loves the expanse of space and has seen service throughout the galaxy and even met his wife, Janet whilst travelling the spaceways.

Hannibal was an able strategist of the Clone Wars. Many now famous people had served under his command, including such people as Crix Madine and Motti and by the end of the Clone Wars he had reached the rank of Colonel.

It had become apparent that major corruption had set into the roots of the Republic. Determined to oppose such degradation, he retired from the Military Service, and with the help of his friend, Bail Organa, campaigned for the restoration of the old proven values. Hannibal was successful in his quest and was elected to become a Senator within the Imperial Senate. During his time in office, he attempted to restore the ways of the Old Republic, and soon discovered the government was eroding. Through compromise, Palpatine was elected to the position of President Of The Republic to help in the restoration of order. Eventually, order was restored, but over the years Hannibal became more and more critical and vocal of the methods used by Palpatine. Corruption still flourished and Palpatine's demands for greater autonomy grew, as did his power. Hannibal was forced to flee with his wife and young son, Bakki, to a remote planet in the Fakir Sector. He was forced into hiding in much the same fashion as did others of his time such as Adar Tallon and General Kenobi.

Bakki soon grew up. Hannibal, although silent, had kept his ear to the ground and made contact with a group of roughnecks named appropriately, the Reekeene Roughnecks. The group took Bakki under their wing as he had become an amazing starfighter pilot. Hannibal kept in contact with the Roughnecks and vowed that he would repay them for their kindness to his son. In a few years time, that debt would be repaid.

Hannibal, after some time, returned to help his friends in their fight against the Emperor, and was taken into the ranks of the Rebel Alliance by Mon Mothma. Due to his expertise in the Fakir Sector, Hannibal was sent to the Fakir Sector Force as Chief of Staff and Military Commander. Finally, Hannibal realised, the debt to the Roughnecks would be paid. Initially, Mothma wanted Romilar to join the Council, but Hannibal insisted that he shouldn't be nominated as he wanted to take a position "near the action". Hannibal has become well known for his ideas and tactics.

One of Hannibal's missions that has become well known, although has never been put into practice, is the idea of penetrating the Kessel Spice Mines and rescue any rebel agents or sympathisers held there as prisoners. Not only has it been rejected by the council, Hannibal has not been able to find anyone courageous enough to attempt to complete the mission.
