Boulderfield

Boulderfield is the cargoship between Chris Redfield and a boulder from the Resident Evil fandom, most notably Resident Evil 5.

Canon
In Resident Evil 5, during the ending fight with Albert Wesker, Sheva Alomar reaches the end of the volcano path, Chris Redfield finds he has to create a stepping stone by moving a boulder at the edge of his path. Hyped on adrenaline, Chris struggles to push and manages to punch the boulder into the lava to save Sheva.

Fanon
Boulders have been a part of the Resident Evil games since its conception. They are normally set up as environmental hazards which usually result in death. The most notable one has been the boulder in Resident Evil 5 in which Chris punches one to save his partner.

The whole scene was so ridiculous - even for the legendary Chris Redfield to do - in the eyes of the fandom, it's become another reason why RE5 is one of the more interesting games of the series.
