Oh I just think of a new guy : Caligula!

This is Caligula, the best general ever:
1. Unhinged Loon (He's insane.)
2. Dangerously Mad (He is!)
3. One of the Gods (He thinks he is.)
4. Bloodthirsty (Well, you see...)
5. Uncontrollable Rage (Yeah, he's insane, after all.)
6. Pathetic Attacker (Concerning the "Britannia Expedition.")

He also has some cool ancillaries:
1. Senatorial Horse (CA's special for Caligula, I bet.)
2. Mistress (His own sister, Drusilla.)

That is the general who is better than Hannibal. He is really cool, Caligula, emperor of Rome.
