Akuma

Akuma, known as Gouki (豪鬼) in Japan, is a character from the Street Fighter series. He is a cold and extremely powerful warrior whose sole purpose of existence is to hone his fighting skills by battling and destroying strong foes. He rarely displays any sign of emotions, aside from occasional bursts of anger. He is Gouken's younger brother and Ryu's adoptive uncle.

Akuma appears in Street Fighter X Mega Man as a secret final boss. To fight against him, Mega Man must obtain a perfect victory (win without getting hit) against four or more bosses.

As the true final boss, Akuma is the strongest enemy in the game. Like in his boss incarnations in Street Fighter, he fights as a more powerful version of Ryu. Akuma attacks with the Gou Hadouken, though less frequently than his other attacks. The airborn Zenku is his most used projectile, where he jumps into the fires two Hadoukens. He tends to follow this up the Shakunetsu Hadoken, which is faster and much more damaging the standard Gou Hadouken, and also travels through Megaman's projectiles. His Shoryuken and Tatsumaki are both stronger versions of Ryu's, though the former doesn't pose much danger since it can only hit Megaman when he's near him. The latter needs to be jumped over while Akuma rushes towards Megaman. Akuma also uses a downward kick while jumping, and a version of Kongou Kokuretsu Zan that has him jump off screen and then come back down and releasing the shockwave. His special is the lethal Shun Goku Satsu, which has him move at greater speed across the room and kills the Megaman instantly.

Akuma opens up the fight with the Shun Goku Satsu, so be sure to jump over him when he does. He usually will stay on side of the screen and either jump and fires his Zenku Hadouken, or stays on the ground and fires Gou Hadoukens, before firing Shankunetsu Hadoken. When moving across the screen, he will alternate by moving using his jump kick or preform two Tatsumakis followed by a Shoryuken, or use Ashura Senku, which causes him to travel much faster. Whenever Akuma builds up his special power again, he'll use the Shun Goku Satsu.
