At first glance, one might not see much in common between the innocent, sheltered Miranda and Portia of The Merchant of Venice, who knows the world well enough to be able to disguise herself as a a lawyer and successfully plead a case; however, the two women share likenesses.

First, each is the daughter of a powerful father who goes to lengths to control his daughter's marriage choice.

Second, each young woman has the capacity to lash out harshly against a character who is an "Other." Miranda has hard words for Caliban, a "monster" who tried to rape her, while Portia has hard words for Shylock as a Jew lacking in mercy.

Third, and most importantly, both women share the trait of empathy. For instance, Miranda is upset when she thinks the men on the ship caught in the tempest might drown. Portia famously states that the "quality of mercy is not strained" (overburdened with use). Both women put a high value on compassion, at least toward people who haven't violated their moral norms.

Antonio, the chief villain in William Shakespeare’s play The Tempest, in some ways resembles Iago, the chief villain in Shakespeare’s play Othello. Antonio acts as a tempter to Sebastian in much the same way that Iago acts as a tempter to Roderigo. However, not only does Antonio tempt Sebastian to do evil, but he also, like Iago, concocts evil plans and manipulates Sebastian as Iago manipulates Roderigo. Both villains are skilled at using clever language and false reasoning to persuade the men they tempt. Both Antonio and Iago seem to have contempt for the idea of moral or conscientious behavior, as in the following exchange in The Tempest:

Sebastian. But, for your conscience?

Antonio. Ay, sir; where lies that? if 'twere a kibe,

'Twould put me to my slipper: but I feel not

This deity in my bosom: twenty consciences,

That stand 'twixt me and Milan, candied be they

And melt ere they molest!

Finally, both Antonio and Iago seek to persuade others to commit murder, perhaps the worst of all crimes.

Significantly, however, Antonio fails in his attempts, whereas Iago succeeds all too horribly.  Antonio, after all, is a character in a kind of play (a “romance”) that has much in common with comedy. Dead bodies abound at the end of Othello; in contrast, everyone manages to survive by the end of The Tempest. Iago is perhaps the greatest, most frightening villain Shakespeare ever created; next to him, Antonio is a rank amateur.

The same is true of Antonio in comparison with another great Shakespearean villain: the title character of his play Richard III. Richard, like Iago, is shameless in his evil. He is intelligent, articulate, clever, and totally unprincipled.  Again, Antonio seems a “piker” compared to Richard III. In The Tempest, Shakespeare created a villain who pales in comparison with some of the villains he had earlier created.

The character of Ferdinand in William Shakespeare's play, The Tempest, is a typical young male romantic lead, derived from the character of the "puer" or innocent young man who was at the enter of the plots of many Roman comedies. This is a stock character, normally found in love with the "puella" or young girl, and a major plot or sub-plot element is how their love succeeds or fails to overcome some major obstacle. In comedy, the plot tends to end harmoniously with the couple marrying, and in tragedy the ending is often death.

Romeo of Romeo and Juliet is a similar character, but in his impetuous nature lie the seeds of the play becoming a tragedy. Benedick, in Much Ado About Nothing, and Beatrice, in their clever verbal fencing, seem more mature than most pairs of romantic leads; Claudio, and his beloved Hero, are much closer to the Ferdinand-Miranda pairing in their youthful innocence.
