In no order - Buddha, Sasaki Kojiro, Qin Shi Huang, Hades, Jack the Ripper, Poseidon, Beelzebub, Shiva.
Im also excited for Nostradamus and Seigfried from Humanity side & Odin from the side of the Gods.
Buddha vs Bishamonten, Sasaki Kojiro vs Poseidon, Jack vs Heracles, Qin vs Hades were my favs so far.
