Marve-Shupopolous-Gou

The Marve-Shupopolous-Gou is a long train-based Badnik whom Dr. Robotnik created to fight both Sonic and Tails. Marve-Shupopolous-Gou made its first and main appearance in Sonic the Hedgehog Trouple Trouble. The Marve-Shupopolous-Gou is orange and very long, consisting of many cabooses. It is equipped with cannon that can launch spiky bombs from the back of its head.

In Sonic the Hedgehog Triple Trouble, the Marve-Shupopolous-Gou departed from its train station in Sunset Park Zone Act 3 when Sonic and Tails made it onboard its cargo containers on its rear. When Sonic and Tails made it up to the Marve-Shupopolous-Gou, the robot tried defending itself. However, it was all for naught, as Sonic and Tails ended up destroying the Marve-Shupopolous-Gou's head, causing the entire train convoy to come to a stop.

Battle
After passing the Bonus Panel for Sunset Park Zone Act 2, the playable character ends up standing on top of the cargo containers of the Marve-Shupopolous-Gou. Also, instead of showing a result screen, the Bonus Panel comes off the train as it departs, leading the playable to be seamlessly transitioned into Act 3. It consists of an automated section, where the player runs forward along a high speed freight train. Sonic and Tails are able to do the Spin Jump and move backwards or forwards. The only hazards on this automatic section are Bombaberry Badniks, which normally drop spiky bombs on the player, and small gaps between the train cars which act like bottomless pits.

When the player has successfully avoided all obstacles, they will eventually reach to the front of the train, where the Marve-Shupopolous-Gou itself is. Upon the playable character's arrival, it will start to fire bombs from its boiler periodically; these can be avoided by jumping over them. As the boss is fought on a fast-moving track, any lost Rings fall to the bottom and are unrecoverable, making it vital to avoid attacks. The player has to hit a part of Marve-Shupopolous-Gou's head whilst jumping over the bombs to damage it. After doing this three times, it starts exploding with a shocked expression on its face, and then it derails and comes to a stop. After this, the playable character Spin Dashes off the train and head to the next Zone.

Trivia

 * Marve-Shupopolous-Gou's name comes from the English word "marvelous" with the Japanese word "shupo-shupo" in the middle, which is onomatopoeia for the sound a steam train makes. The suffix "-gou" (号) literally translates to "number" or "version", and is often placed at the end of vehicle names.
 * The background music that plays during the Act before the encounter with the Marve-Shupopolous-Gou is a slightly altered unused track from Sonic Chaos, which is accessible in that game's Sound Test.
