Next, let's cover Diesel, the tritagonist of Samus & Joey and Metroid EX. Diesel is a mechanic working on the refueling station Junk Quixote, who Samus goes to for her every repair. After she shows up with Joey in tow, she leaves him under his tutelage whenever she needs to go on a more dangerous assignment. After Greed steals Samus's powerups, Diesel joins Samus and Joey on their quest to take them back.
Diesel floats around on a little flotation device at all time. He can also weld and repair things with surprising swiftness, a trait shared by his entire species as we see later on, who can disassemble entire ships in mere minutes as a swarm. They are also seen using drills and constructing rockets to destroy an enemy ship. Diesel also plants remote bombs and detonates them from afar at one point, and uploads a virus into an operating system. He has a ship of his own called the Junk Hawk.
Here's the moveset I came up with:
Standard B: Repair
He will work quickly, using a number of his tools, to assemble a rocket and send it flying forward at his opponents.
Side B: Disassemble
He can use this move when close to an opponent to deactivate one of their moves for ten seconds, causing it to malfunction when pressed.
Up B: Flotation Device
His little device will float upwards beneath him, carrying him upwards to get at something higher.
Down B: Remote Detonation
He can press this to plant a hidden bomb on the stage, which he can then detonate at a later time.
Final Smash: Junk Hawk
His junk collection vehicle will appear over the stage, carrying a load of broken down ship parts which it will release across the stage.
Entrance: He will be busy working on something and look up.
Taunts: Up, he will hold up a blowtorch and laugh like a maniac. Side, he will accidentally hit himself in the head and grumble out alien swears. Down, he will wiggle around his little tentacles like he's ranting and raving.
Kirby Hat: His ears and his stripes.
Kart: Based on his little flotation device.
Special Move: He will be able to quickly disassemble an opponent's kart, leaving them at a standstill for a few seconds.
Spirit Battle: On Junk Quixote, with Samus and Joey.
Victory Screen: He will stand before a repaired ship and look proud of his handiwork.
Losing Screen: The ship he was working on will fall to pieces around him.
Color Swaps: His normal appearance, with more reddish fur, with green fur, with blue fur, with pink fur, with orange fur, with white fur, and with black fur.
