Lorelei; see you in h-ll shiro! ... wait...
After Dr. Hell used his resources and cyber cr-p to revive Schtroheim Heinrich, Schtroheim made Donau Alpha 1 as a way to surpass Juzo Kabuto's Mazinger Z with Dr H's sci fi cr-p. Dr H wanted to use Donau immediately but Schtroheim wanted to make it better so he ran away with it. to be fair, that might explain why the Mechanical Beasts s-ck and Mazinger always beats em. They were rushed. Look at Sonic 06 compared to Sonic Mania. Schtroheim Wanted it to have its own thoughts and brain and will like a human (so thats where Mega Man X got it from). Baron Ashura found him and sent River F9 to bust his home. But Schtroheim sent Donau out. Schtroheim somehow snuck aboard Ghoul and confronted him/her. After revealing his motives, He tried to stop Ashura from sending the incomplete Donau out but Ashura shredded him with machineguns and threw his bod out. B4 he bites it, he tells Lorelei he made her as the Heart and mind of Donau Alpha 1 and couldn't hand her over to Dr H (kind of a reverse Astro Boy) and tells her his last wish is for her to fuse with Donau and beat Mazinger. Despite Shiro Kabuto's attempts to save her, she does it and goes after Ashura for wasting her pop. After bustin River F9 she faces Mazinger Z against Shiro's pleas and after putting up a pretty epic battle, hers busted by Mazinger. Shiro gets p-ssed and I don't think she went to Heaven or Hell as shes an item.
