MELIODAS SEVEN DEADLY SINS FULL
While he's not invincible, Meliodas was nearly impossible to kill even without the Supreme Deity's Resurrective Immortality curse on him and at full power he's strong enough to withstand wielding every commandment without suffering from Phlebotinum Overdose.

When he defected, it was what caused the War between the Five Races because of the imbalance of power it created between the Goddess Clan and Demon Clan. In his youth, he was the most powerful member of the Demon Clan just under the Demon King himself and was the leader of the Ten Commandments, themselves as a Badass Crew of demons chosen for their overwhelming power.
The Ace: He's strong enough to fell giants, durable enough to take fatal blows like they were paper cuts, fast enough to block and dodge nearly any attack and clever enough to anticipate sneak attacks.
