Nothing is currently known about Ambrosius' personality.
Blue Night Investigation arc
Files containing information about Ambrosius are found in Section 13 by Lewin Light and Ryuji Suguro. It is revealed to them by Mephisto Pheles, that unlike the later cloning experiments, Ambrosius was born normally.
- Ambrosius' first name was given to him in his file from Asylum, but his family name, Faust, was seemingly added later when Amaimon used it as his guise entering True Cross Academy.
