>>6112354It's from the British sci-fi series Primeval, which had creatures from the future and past coming through anomalies to the present day.
Most of the figures were released in two packs so that creature could have come with the guy in green on the right. The show ended in 2010 I think so you'll have to check the second hand market.
They're also in scale with the Doctor Who figures which had some beautifully weird monsters - like the orange guy on the right.
There's also meant to be a Diamond Select Cthulhu, but there aren't many details about that.
