— Bigcat

Bigcat is a displacer beast and the beast companion of Copper. As a beast companion, she is played by both Tom and Matt Colville.


It's not a displacer-beast-sized house!

Bigcat is a displacer beast, large cat-like creatures with six legs and a pair of long tentacles sprouting from their shoulders. While displacer beasts are usually about 9 feet long, Bigcat has been described as being 6 feet long, implying that she is not fully grown.

Despite her menacing appearance, Bigcat acts like a domesticated cat, hence how she got her name.


Bigcat's ability scores are as followed:

18 (+4) 15 (+2) 16 (+3) 6 (-2) 12 (+1) 8 (-1)

As a beast companion, Bigcat loses her innate Avoidance ability and her multiattack action (though can still multiattack with three ferocity) but in return gains the abilities of the Monster Tamer.


Bigcat presumably joined the Chain of Acheron along with Copper. When asked in the first episode how and where he got her, Copper simply replied:

I'm just the best ranger there is.

In A Sapphire Sky, when Scipio asked how he get a displacer beast and if he raised Bigcat from pup he replied:

It is a cat but I raised it better than most people do.

Red Sky at Morning(Episode 1)[]

She was present during the Chain's failed assassination of Mortum in Blackbottom, and Copper used her as a mount to help keep the standard high and guide the Chain to the docks. When a mob of civilians attempted to commandeer the ship the Chain was using to escape the city, Bigcat was integral to the display that scared the mob off.

Behind the Scenes[]

When Tom was creating his character, he wanted to play a ranger with a companion of some kind but did not know that he could have a monster as a companion. At first, he thought a Bulette for a pet would be neat, but he settled on a Displacer Beast.

Bigcat is often called the Chief Mouser of the Chain of Acheron, in reference to the role cards all the senior officers hold. Whenever a senior officer is in danger of dying, the players often joke that Bigcat will receive a field promotion and take their role.
