Y person who knows what Caesar wants for for and the only one who hasn't betrayed him. Antony become allies with the conspires because it will help with his plan to take over for Caesar.

Antony states in his speech that "[Brutus] Hath told you Caesar was ambitious", and then Antony retorts with "I thrice presented him [Caesar] a kingly crown which he did thrice refuse." By doing that, Antony carefully rebuts Brutus' statement that Caesar was ambitious and starts turning the crowd against the conspirators.
Throughout his speech Antony calls the conspirators honorable men. He then says, "You [the crowd] all did love him once, not without cause. What cause withholds you then to mourn for him?" This question goes against Brutus by questioning his speech when he betrayed Caesar. Now the crowd is starting to turn against the conspirators and follow Antony.
Antony then teases the crowd with Caesar's will, which they beg him to read, but he refuses. Antony tells the crowd to "have patience" and expresses his feeling that he will "wrong the honourable men whose daggers have stabbed Caesar" if he is to read the will. The crowd yells out "they were traitors" and have at this time completely turned against the conspirators and are inflamed about Caesar's death.
To refute Brutus' claim that Caesar was a heartless tyrant Antony recounts "how dearly he [Caesar] loved him [Brutus]". Next, Antony humbles himself as "no orator, as Brutus is" hinting that Brutus used trickery
