Jill & the Drill Dozer
Jill and the Drill Dozer (ドリ・くるり＆ラセンダー8, Dori Kururi & Rasenda 8) refer to the main character and her vehicle respectively from the Game Boy Advance game Drill Dozer.
Jill is the sole playable character and anti-hero of Drill Dozer for the Game Boy Advance, her only non-Smash Bros. appearance. She is the daughter of Doug, who is the leader of the Red Dozers (a group of thieves). It is said that for years many groups of thieves have been in search for the Red Diamond, which is a powerful diamond that would grant its owner any wish. Luckily Doug’s wife was the person who found it and gifted it to Jill before she died. Though the Red Dozers are a group of thieves, they are kindhearted and only protect the diamond instead of using it for corrupt wishes. Jill is temporarily given the role of boss to reclaim the Red Diamond from the Skullkers, a gang of thieves who are paying the local police force to arrest any rival gang, while her father is taken out of commission. At the end of the game Jill is given the permanent role of Red Dozer boss, as the Red Dozers seek a new adventure to rebuild their destroyed home using profits from stolen treasures.
In Drill Dozer, Jill pilots the titular vehicle, a small mech suit with two arms that form into a big drill. The Drill Dozer can drill, jump, slide, and in certain stages swim and fly. Throughout a stage Jill will have to collect gears so she can shift up the drill into second and later third gear, this allows her to break more durable walls and drill indefinitely. Drilling serves multiple purposes, with its main purposes being to take down enemies and destroy things blocking Jill's path.
As an Assist trophy
Jill rides around the stage on her Drill Dozer, its drill spinning and dealing continuous damage and low knockback to fighters hit by it. Jill occasionally jumps, though not high enough to reach the upper platforms. Jill despawns after a while, though she can also fall off ledges.
A young girl who takes over the leadership of a band of righteous bandits known as the Red Dozers from her injured father. Jill sets out on the Drill Dozer to recover a red diamond stolen by the Skulkers. Jill has great reflexes and rode the Drill Dozer instead of a baby carriage growing up. She has an intense dislike of studying, however.
In Super Smash Bros. Ultimate
Jill returns in Super Smash Bros. Ultimate. She appears as a Spirit alongside her Drill Dozer, but is no longer an Assist Trophy. Her Spirit can be summoned through cores from Duster (a fellow thief) and Drill Man (a character who also uses drills).
