Del Lago

Del Lago is one of the first bosses in Resident Evil 4.

Characteristics
It is a massively overgrown, fattened being vaguely resembling a salamander. More than six metres in length, it has an immense maw with several rows of teeth, and from what seems to be its throat, countless, writhing Plaga thentacles emerge when it swims in attack pattern. Capable of devouring complete humans, it is a true leviathan residing in the lake nearby the Village's church. It has no discernible eyes, but is speed is deceptively fast in water.

Role in Resident Evil 4
It is first mentioned in a file found by Leon near the church, where it is said to be "awakened" by Saddler to guard the pass across the lake. Leon then fought it in a small motorboat anchored in the lake's shores. By continuously darting spears at Del Lago's massive body, Leon eventually felled the beast, which then sank to the bottom of the lake, finally defeated.
