Otho

Otho, who styled himself as Otho Nero in tribute to the ever people-popular Nero, was declared emperor by the Praetorian guard, after turning hostily against Galba and using his connection to Nero to underscore and build his popularity.
 * he carried on very much in the self-same style of Nero;
 * he renewed construction on the Domus Aurea

Otho commits suicide after Vitellius is declared emperor by his legions.
