The Young Male Titan. This is a big boy, standing about 30% taller than the regular action figures (which still seems short for a titan, tbh). Pretty straight-on Greco-Roman inspiration for the design here, which is sort of appropriate.  

The action figures with removable helmets (the Ogre King, Northlord and the fire giant Metaflamme) really amuse me. The helmets look so cool and appear as if they would fit perfectly, but as soon as you put them on the head, they are wobbly and oversized. I imagine this was a challenging toy design problem at the time, so I appreciate that LJN even attempted it and, more so, managed to get the eye holes to line up properly.
