I chose Scipio as a screenname. Name after famous general Publius Cornelius Scipio (Africanus) who defeated the legendary Carthenian general Hannibal Barca at Zama.
Considering Tulius had the Gaius Julius Caesar vive going down it was the only other logical choice.
Augustus was a title bestowed upon Octavian after he concluded a long series of civil wars within the Roman republic (mainly by defeating Mark Anthony's - and Cleapatra's fleet at Actium, and all other claiments were dead), basically declaring him emperor. Octacian was the adopted son of the legendary Gaius Julius Caesar, and the word Caesar was later used as a title for emperors. The German word "kaiser" and the Russian word "Tsar" are derived from Caesar I believe, thus expanding Julius Caesar's legacy for centuries.
