I seriously doubt that we would get the 4th arc animated, but if by some miracle that gets animated, I think one of those should voice him:

Jun Fukuyama (Lelouch Lamperouge, Koro-Sensei, Yumichika Ayasegawa)

Mamoru Miyano (Berg Katze, Prince Demande, Light Yagami, Yao Ling, Chrollo Lucifer)

Mamoru Miyano is my personnal favorite of those two because his "Berg Katze" voice is so goddam insaneit's not even funny. Jun Fukuyama is stilla great VA though.

At first I thought of Takehito Koyasu (Dio Fucking Brando), but he already voiced Rizer.
