OVV quasar

An optically violent variable quasar (often abbreviated as OVV quasar) is a type of highly variable quasar.

It is a subtype of blazar that consists of a few rare, bright radio galaxies, whose visible light output can change by 50% in a day.

[2] OVV quasars have essentially become unified with highly polarized quasars (HPQ), core-dominated quasars (CDQ), and flat-spectrum radio quasars (FSRQ).

At visible wavelengths, they are similar in appearance to BL Lac objects but generally have stronger broad emission lines.
