Hilda Bidan

Hilda Bidan is a Lieutenant working in the Research and Development department of the Titans along with her husband Franklin Bidan. An expert in metallurgy, she studies the various types of metals and compounds used to create the armour of mobile suits and weaponry. She discovered along with her son Kamille that her husband had a mistress named Margarita, instead of being outwardly upset she buried herself in her work in order to ignore addressing the issue.

When it became known that Kamille had stolen one of the Gundam Mk. II's, Bask Om had both Hilda and her husband brought on board the Alexandria as hostages in an effort to regain the stolen Gundams. Placed in a capsule, she was sent out in plain sight of the Argama and its crew. When Kamille attempted to retrieve the capsule, it was destroyed by Jerid Messa under orders of Jamaican Daninghan, killing Lieutenant Hilda.
