Let me tell you what's Mary Sue.
It is an Antonov-225 cargo plane retrofitted to carry more weight. But wait, that's not all.
It also carries two Goalkeeper CIWS on its side and a Phalanx CIWS on the other. The wing is equipped with Bofors guns salvaged from P-51 Mustangs, and it can carry a Lynx (modified Cessna fit for war) inside its cargo bay.
And oh, did I mention that it's also equipped with afterburners and an ECM and AWACS system?

(some dude made a remark about it's not as mary sue as the cost is skyhigh)

Well, since it's operated by a Tongan crew who is employed under a top-secret organization that funds the CIA, Al Qaeda and Aperture Science, whose job is to protect world peace through power, the plane's costs are paid by the organization. That includes the onboard Jacuzzi which I forgot to mention in the last post.
