Square Enix implemented its president and CEO Yosuke Matsuda as a special lvl.99 boss for its Final Fantasy 15 promotional livestream.
While not in the actual retail game, a recent presentation of Final Fantasy 15 included the publisher's executive as part of a "mystery disc" uniquely made for the livestream. (Thanks, Gematsu.)
Beginning at the 3.02.37 mark you can watch the businessman descend from the sky and produce a magical sword out of thin air. He later manifests a tommygun and emits lasers from his eyes, because of course he does.
As of yet, there's been no formal announcement of this bonus content coming to the main game. Perhaps it will be available as DLC or hidden as an Easter egg?
In the meantime, you can read our full review of Final Fantasy 15, which just went live this morning.
