This is a Voltron third Dimension Stealth Yellow Lion, made by Trendmasters in 1999.  In 1999 Voltron the cartoon was relaunched as a cgi show.  They called it Voltron the third dimension. The story line picked up where the cartoon left off.  But they decided to add another plot line to it, now our heroes could travel to another dimension.  So in our universe you had the ultra cool Voltron we all know and love.  But also when they went to that other dimension their lions changed and so did Voltron.  This is Stealth Voltron's left leg the stealth yellow lion.  If you buy all five Stealth lions you can form Stealth Voltron.  This toy is unopened and in good not mint condition.
