Akuma is easily one of the most complete characters in Street Fighter V: Arcade Edition. He has a high damage output, and both of his V-Triggers are very useful in a variety of match-ups.
The more versatile of his V-Triggers is arguably his second one, the Shiretsu Hasshi, which allows him to cancel specials into EX specials without EX bars. Not only is this useful for maximizing damage off of your normal hit confirms, but as this video shows, it’s useful for maximizing damage off of whiff punishes, and even for creating setups.
