Okay, here's the finished figure.
You will notice that not all parts made it into the final custom, but that's the way things are...
But first his background story:
Born 69 BBY, Gar Ahab was the son of A’lan Ahab and his wife Jori.
He was brought up in traditional Mandalorian fashion and worked as a mercenary and occasionally as a law enforcer throughout the galaxy. 31 BBY he was contracted by the Board of Commerce of the planet Alba-16 in the Mid Rim to protect their member companies from the organisation of the Crime Lord Spadda the Hutt.
Ahab went to work with his usual precision and ruthlessness, but was double-crossed by his employers when Spadda used huge amounts of Credits to bribe them. The situation got out of hands and peaked in a shootout during which Ahab not only killed Spadda’s favourite brother Nada and his bodyguards, but also the Chairman of the Board of Commerce. Lacking hard evidence to prove the Chairman guilty, Ahab had to leave the planet and accepted Jango Fett’s offer to work as an instructor for Commando soldiers on Kamino.
This band of Training Sergeants became known as the Cuy’val Dar (Those who no longer exist).
He proved to be a very effective instructor whose squads conducted countless successful operations during the war.
When General Arligan Zey, Director of Republic Special Forces, called for the former Cuy’val Dar to cross-train experienced Troopers for Special Operations, Ahab, now a wealthy man, answered the call and travelled to Coruscant out of a feeling of responsibility for those who he considered his boys.
Upon the cease-fire, he and most of his Commandos appeared on the casualty register as KIA during the Separatist attack on Coruscant, but rumors now have them on Mandalore hiring out as an independent mercenary unit.
