Street Fighter X Tekken/Kazuya
From Shoryuken Wiki, Marvel vs. Capcom 3 Strategy and More!
As a child, Kazuya was thrown off a cliff by his father Heihachi, due to him being a "weakling". Kazuya managed to climb back up after gaining the power of the Devil. He became a vicious and evil man from then on, hating his father for what he did. Kazuya had a son named Jin Kazama, who hates him as much as Kazuya hates his father. Kazuya has mastered the power of his Devil transformation and has become one of the most powerful characters in the Tekken series.
In a nutshell
Kazuya is an all around, close range character. He lacks a projectile but can easily avoid projectiles and get in close with his Mist Step and Uppercuts. Once he gets in close, Kazuya becomes a monster. He has a multitude of tools for any situation, like uppercuts, his Demon God Fist (an excellent combo ender), his Slaughter Hook, and his many Tekken combos. Due to Kazuya's lengthy combos great moveset, Kazuya is a very reliable character.
