Mezco ThunderCats.

In 2011, Mezco shipped the first cartoon-accurate ThunderCats action figures the adult-collector market had ever seen. The 14-inch Mega Scale line ran through 2017 across eleven releases: five core heroes, six SDCC and retail variants, and a Plush Snarf. At New York Toy Fair 2026, the brand confirmed ThunderCats is returning at 6-inch One:12 Collective scale, and at San Diego Comic-Con 2026 the One:12 Lion-O finally appeared in the flesh.

This page is the catalogue. For the One:12 Collective reveal, the 5 Points set, pricing across every ThunderCats line and the news as it lands, see the complete Mezco x ThunderCats hub.

Rough sculpts and paint tests Mezco surfaced during the Mega Scale run, before any of these pieces went to production tooling. Some made it through to the 14-inch line on the shelf above. Others, like the Mumm-Ra mummy-form sculpt, stayed on the workbench.
