 In " Space Seed " , Khan is presented as having several positive characteristics : he is gracious , smiling , fearless and generous . He is not threatened by the success of others , and encourages their self @-@ esteem . He is also ambitious , desiring a challenge commensurate with his abilities , but this ambition is not tempered by any consideration of the rights of others . Author Paul Cantor asserts that Khan is a mirror image of Kirk , sharing his aggressiveness , ambition , and even his womanizing tendencies , but possessing them in far greater degree . During the episode , several of the characters express their admiration for the man even as they oppose him , with Kirk referring to him as " the best of the tyrants , and the most dangerous . " The character 's Spanish accent and superhuman appearance strongly differentiate him from most Star Trek characters .
