One of the big surprises this past year at SDCC was the discovery that Mattel had acquired the Thundercats license. This news was immediately followed up with the announcement of a new Thundercats action figure subscription to be available on MattyCollector.com. They even had two early versions of Lion-O and Jackalman.

 

Figures in this subscription include:
Lion–O™ (09/16)
Jackalman™ (10/16)
Pumyra™ (11/16)
Panthro™ (12/16)
Club-exclusive: Mumm–Ra (11/16)

This differs than the initial announcement’s lineup with two figures missing, Jaga and Grune.

You can order your subscription here.
The ordering window will close on Friday 2/26/16 at 11:59 p.m. PT.

I came across a link on Twitter that was retweeted by one of the writers on the new Thundercats show currently airing on Cartoon Network. The link pointed a tumblr page with an image of different species from Third Earth, the planet, on which, the series takes place.
The text of the tweet I followed was:

This probably shouldn’t have been released, but it’s on this guy’s Tumblr, soooooo – species of Third Earth: skullgrin140.tumblr.com/post/830086461…
