Complete Monster: Richard Hawk is the evil Vice President who ousts the heroic Michael Wilson from office, proceeding to turn the US into a military dictatorship under his control. Using prisoners of war as shields, Richard proceeds to order them gunned down while also attacking American cities in an attempt to kill Michael, now piloting the mechanical armor known as Metal Wolf. Richard reinstitutes slave labor, selling people in Miami into white slavery, and attempts to frame Metal Wolf by using poison gas to wipe out Chicago before also using a giant mech to try to wipe out New York. When Michael defeats him, Richard attempts to flee to space, where he has prepared a superweapon to wipe out all of the United States out of spite at his loss.
As if Richard's atrocities in the 0% Approval Rating entry on the main page weren't enough, he enacts a law that calls for the immediate public execution (by guillotine) of any Metal Wolf sympathizers who don't confess by a previously set timeline. Along with their family members within four separations. And their old classmates. AND their friends and coworkers.
The whole game is this. Foreign game has the U.S. President saving the U.S. by killing lots of people? Offensive. US President saving the US by staging a one-man war on his Vice President in a mecha suit while blowing lots of shit up and spitting out cheesy one-liners in the most hot-blooded fashion ever? Awesomesauce.
Richard and Michael's relationship is very... charged to say the least. Richard even points this out during one battle. Later that same battle, he sounds like he confirms this with the line "I'll...hug you to death!" However, his delivery of this line might suggest that he's just running out of effective tauntsto begin the fight with, especially because he delivers this line late in the game. But then again, that theory gets thrown out of the window later in that same fight...
... Are those mechs arm-wrestling? Over the podium with the President's seal? While onlookers cheer them on?
Fridge Logic: If you kill any Metal Wolf sympathizers (and their family up to four separations, and friends and co-workers, and their friends,family, and co-workers) Won't you have to pretty much kill the entire nation at that point- Oh wait Metal Wolf Chaos. Never mind then.
Fridge Brilliance: Would you really put it past Richard Hawk? He did try to nuke America from orbit after all!
Ham and Cheese: Arguably a completely intentional version of this (as in, the developers were aiming towards this effect). You can practically hear the voice actors laughing in the studios as they're recording.
Jodie, after Michael defeats Warner and she is rescued: Mister President... How can I ever... Michael: Jodie? Jodie: Yes? Michael: ... Sorry to be late.
The very beginning of the mission also qualifies. Despite them falling to Richard's propaganda and abandoning him, Michael still decides to go rescue his fellow men, since he "... can't turn [his] back on a friend."
"Holy Shit!" Quotient: Taken to unbelievable absurdity. At one point Michael destroys an orbiting space colony and then rides a piece of debris back down to Earth like a surfboard.
Mexicans Love Speedy Gonzales: This game has an enormous fanbase among Americans. There is one thing offensive about the game to most Americans who have heard of it: Its release being Japan-only until 2018 where its XD port got an international release.
Narm Charm: The voice acting and writing as a whole. It's ridiculous, insane, and completely over the top. The voice acting is pure Ham and Cheese. The premise is ludicrous. And yet, this game wouldn't even be half as good if it wasn't so corny.
Signature Scene: First mission: the front flip Rocket Jump out of the White House. Spoiler: the White House explodes behind him as a result. It was even used prominently in Devolver's big E3 reveal as if to say, "You're not imagining this, we're doing it!"
So Bad, It's Good: This game embodies this. If it was a movie, it'd be the single greatest B-Movie ever made. Only applies to the storyline, though; the actual gameplay is good, by all accounts.
That One Boss: The Ultimate Weapon's second form doesn't pull any punches. It launches a shit ton of missiles that will shred you apart if you're in one spot for too long. In addition, the thing has shields, which can dampen the damage of a ill-timed Super.
