Extender

Extendar is a character from the Masters of the Universe franchise. A member of the Heroic Warriors, he is a cyborg warrior who appears at first to be an ordinary knight in silver armour, his face shielded by a visor. However, he is able to mechanically extend his limbs, waist and neck to extreme proportions until he towers above his opponent, attaining invincibility at his full height.

Occasionally referred to in comics as the 'Tower of Power', Extendar was introduced into the Masters of the Universe toy line in 1986, at a stage when the toy line was breaking away from its roots in pure fantasy, and introducing more robotic and mechanical characters.
