The Thundercats Classics line was released by Bandai to go alongside the rebooted Thundercats toys. The line, even though it was 4 figures and 2 exclusives, was designed to bring back the classic characters in an upgraded form.
SDCC Lion-O comes in a very plain cardboard box. The outer sleeve comes with the Classics logo and the classic insignia on the front. The bottom of the box, is Lion-O's name. Inside the box, we have the figure itself, with the accessories on place. Mold wise, this is exactly the same as the standard release figure, however the differences here are that his leotard is painted in a metallic blue, his skin has a dark wash on it to bring out his muscles and other details. His Sword of Omens in both forms are now in a vac metal or chrome plastic.
His accessories are: 2 swords, claw shield, connector piece, alternative hands and stand for the sword. You can place the dagger form in the stand and place the Claw Shield on the base. His articulation is in the neck, shoulders, biceps, wrists, abs, waist, hips, knees and ankles. As this is an SDCC exclusive, it's very hard to come by and commands around $150 on the secondary market, especially for a boxed version.
