Wanted to share with fellow KO kollectors on these following points for this KO Oversized Warbotron Rex, which some reviews of this figure may have accidentally missed out :
(1) Crown can fit onto robot head snugly by tabbing in the small peg to the screw hole (back of head) first.
(2) Dino knee-thigh pieces should be extended ( and thus likely the robot elbows retracted in ), if according to the box front artwork and/or the G1 toy.
(3) Chromed tail pieces can slide up to lock in place in dino mode.
Personally I like this figure very much as a nice representative of the Grimlock character.
