Hope first started building it in Knothole, and finished work on it somewhere in the United Federation. But when she used the plane to return home to Knothole, she found it been reduced to burned ruins by the Eggman Empire. She was so enraged at her step-brother, Snively Robotnik, for lying to her and further disgracing their family name that she took on the Egg Fleet herself as it attacked New Mobotropolis.

She escaped being blasted out of the sky, however, and went to work as an engineer for the Guardian Units of the Nation. (StH: #162, #177, SU: #1)
