Players who like to be in control should opt for Nightmare, the main antagonist of the Soulcalibur series. This is a heavy, tanky character that carries a huge, thick sword that deals a lot of damage.
Nightmare is best at mid-range with strong mix-ups. Use quick pokes to never let any opponent get close to you, and then activate your Soul Charge for an ultimate blowout.
Additionally, in Soulcalibur 6 Nightmare gains a new personal mechanic -- Revenge. This is one of his most devastating attack mechanics that involves a succession of horizontal, vertical and kick attacks that all end up in a Terror Charge.
