As known, the Shakespeare Caesar was very ambitious, even overly ambitious. This is shown through both his military achievements and Brutus’ words, where Brutus said that Caesar's downfall was because of his ambition.

The biggest resemblance between the two characters is that they both were ambitious, as in real life, Caesar also had many military feats, including the defeat of Pompey and the victories at Gaul. Furthermore, Caesar's political ambition was second to none. Being born into a family that was not influential at all, he rose the ranks at impeccable speed. He also put much effort into reforms of Rome, such as calendar revisions and enlarging the Senate.

Shakespeare Caesar was clearly power-hungry. We know this through Caesar declining the crown three times (psyche tactics) and him going to the Capitol even though convinced not to by his wife, as the thought of being king overwhelmed Caesar's judgment.

Akin, the actual Julius Caesar was also power-hungry, where he was offered a diadem and declined it, and his recklessness regarding preparation in battle (he wanted control as quickly as he could get it). The amount of territory claimed by Caesar also shows his drive for power.

In the play, Caesar was characterized as generous through his will, where it stated that he was to give the people money and land, free to roam. He wanted every Romen citizen to get 75 drachmas and the land that he owned be made into parks and gardens.

Similarly, Caesar’s generosity was shown through his treatment of enemies. Caesar was notorious for treating his defeated enemies much better than what the norm was, which also partially led to his downfall. Caesar's will also was the exact same in real life as the play, illustrating the plan of donations.

Fictional Caesar had no bodyguards, as he thought he would live forever and was a god, which depicts his arrogance.

Actual Caesar was alike, where as a result of his arrogance, he was blind to the harm he was causing other people (war) and what others were planning against him (conspiracy).
