A massive, grayish-white shark-like creature swims forth. Its head is horrifically human-like in appearance, but completely hairless, having neither hair, nor eyebrows, nor lashes. Its teeth are long and pointed and its tongue is forked and brown in color. Its shark-like pectoral fins end in three-fingered claws and it has two dorsal fins, side-by-side. Its tail fins curve sharply and are a bit lighter in color than the rest of its body.
Speed swim 60 ft.
A renzer usually initiates combat with its spell-like abilities, using a cone of cold to blast its foes. In melee combat, a renzer focuses on bite attacks and once it locks its teeth on an opponent, it rarely lets go until either it or its opponent is dead. If fighting a surface-dwelling race or air-breathing creature, a renzer often grabs the opponent and dives straight down, swimming as fast as it can in hopes of drowning the foe. If outnumbered or overwhelmed, the renzer moves a safe distance away and uses its command fish ability.

Twice per day, a renzer can command fish and aquatic creatures as the mass charm monster spell (caster level 8th). The renzer can communicate with any creature it currently commands as if by speak with animals.
