Mettalum Olympus
From Warhammer 40k - Lexicanum
Mettalum Olympus was an Imperator Titan commanded by Princeps Goethe.[1]
It managed to almost single-handedly hold back a Tyranid invasion on the ash-choked plains of Horst Prime. The titan was surrounded by an entire horde of Hierophant bio-titans and its plasma reactor was breached by their frenzied attacks. The resultant explosion vaporised everything for a kilometre around and left a crater that is still visible from orbit.[1]
