Anti-Hero: Jake, to Nominal Hero levels - he's out to get retribution on the gang that killed his brother but isn't afraid of murdering completely unrelated civilians and police officers in order to execute needlessly elaborate plans. The game takes this further, by cutting out of the action to a cutscene or different style of play, or even a different area.
And Now For Something Completely Different: The prologue sets the stage for it, with it jumping from biking to turret sequence, to brawler sequence, to a cutscene of Jake on a motorbike jumping over a Huey helicopter. Ambiguous Disorder: Between his limited emotional range and his penchant for ridiculously convoluted solutions to his problems, you'd be forgiven for thinking Jake has something wrong upstairs. This is while said baddies are still dying in the same room. All Women Are Lustful: Every single woman encountered in the game save one will immediately offer themselves to Jake even after being rescued from sexual assault or after their partner has been beaten up. All There in the Manual: Wonder why Jake lives, despite taking multiple gunshots after Mikey's death? The game files state Jake was experimented on in Vietnam, and his enhanced endurance was a result of this. At the same time, the "1%" on the game's full title is a reference to the estimate that only 1% of biker groups are "outlaw" gangs. Jake proves his innocence by murdering them all. A group of miners automatically assume Jake is Devil's Hand because he's a biker, and start a fistfight with him over the damage the Devil's Hand has done to their community.
