The Gladiator Overdrive is an overdrive/boost pedal from AD Pedals, a maker of compact effects pedals. Pedal of the Day describes it as "creating a new and exciting overdrive/boost with lots of range to experiment with", and notes that it takes elements of the famous Klon pedal and puts its own spin on those tones, "but with a little more grit and dirt to it"1. If you are weighing it against other circuits, it sits in the territory covered by Overdrive Pedals and Boost Pedals.
What it does
The Gladiator is built around range. Pedal of the Day found that the Gain control sweeps through two different distortion sounds at either end of its travel, with the cleaner sounds focused around the 10 to 11 o'clock position of the knob. That makes it usable both as a light, always-on push and as a fuller overdrive, depending on where the Gain sits1.
The reviewer's overall verdict was enthusiastic:
"Get ready to get shot down in a blaze of glory with this one, people, it's a rocker1!"

Where it came from
The Gladiator takes its starting point from the Klon, the overdrive pedal that Pedal of the Day calls "that certain mystical pedal that few of us can afford". Rather than reproduce it directly, AD Pedals kept elements of that circuit and voiced it with a little more grit and dirt1. Aion FX, an independent project page, also documents a Gladiator Dual Overdrive, a dual-channel overdrive project in the same family2.

Questions
Is the AD Pedals Gladiator Overdrive a Klon clone?
Not exactly. Pedal of the Day describes the Gladiator as taking elements of the famous Klon pedal and putting its own spin on those tones, with a little more grit and dirt than the pedal it is based on. It is best understood as a Klon-inspired overdrive/boost rather than a straight copy.
What kind of sounds does the Gladiator Overdrive cover?
Pedal of the Day found a big range of overdriven sounds across the Gain knob, with two different distortion sounds at either end of the sweep and cleaner tones focused around the 10 to 11 o'clock position of the Gain control.
