YMMV / Mario Brothers

• Complete Monster: King Koopa is the power-hungry ruler of the Koopa Troop and is far more villainous than his game counterpart. Obsessed with getting his hands on the Life Mushrooms, Koopa rallies his troops to storm Princess Toadstool's castle and kill her if she does not reveal their location. When the Mario Brothers attempt to stop his schemes, Koopa kills Luigi by using his fire breath to burn him alive. Koopa leads his army on an assault against the Princess's castle, killing dozens of Toads who were protecting her. Once it becomes clear that the Princess won't hand over the Life Mushrooms, Koopa kidnaps her to learn how to create them for himself. He then sends a legion of Hammer Bros. to round up the remaining Toads for his own purposes. When Mario finally confronts him to save the Princess, Koopa proceeds to taunt him over Luigi's death and promises that he will share his brother's fate.
• Harsher in Hindsight: Bowser would eventually officially undergo Adaptational Villainy in The Super Mario Bros. Movie, but even that portrayal of Bowser is nowhere near as vile as this one.
• Nightmare Fuel: Bowser is far darker than any of his official depictions, and then there's the flood of lava that kills everyone in the end.
• Once Original, Now Common: Mario sprite Flash movies are nothing new nowadays, and this series is frequently compared to other sprite movies such as Rise of the Mushroom Kingdom. However, this was one of the first (if not the first) Mario sprite Flash animations of this scale and was in fact the direct inspiration for Rise of the Mushroom Kingdom.
