The Speedwagon Foundation (スピードワゴン財団 Supīdowagon Zaidan), often abbreviated as "SPW", is a powerful and influential organization created by Robert E. O. Speedwagon in 1910, funded by the money he made from the oil he discovered in the United States.
It is primarily featured in the second, third, fourth, and sixth parts of the JoJo's Bizarre Adventure series, with an alternate version of the group having a minor role in the seventh and eighth parts.
The foundation dedicates itself to medical research and environmental conservation, but it has also helped the Joestars countless times through intel, supplies, and backup. The foundation also has connections with underworld groups and studies many supernatural phenomena, such as the Pillar Men and Stands.
Their first noted action was the investigation of the ancient Mexican temple where the Pillar Man Santana slumbered. Speedwagon Foundation scientists subsequently sheltered the remains of Santana after his defeat, and uncovered a prediction announcing the awakening of three other Pillar Men in the same year. The foundation's Special Fighting Technological team also fought alongside the Germans against Kars' vampire army.
The Speedwagon Foundation effectively continued to help the Joestar bloodline throughout the 20th century. In 1988 and 1989, they aided the third Joestar Group in reaching Cairo, through reconnaissance intel and various modes of transportation. Moreover, doctors from the foundation helped with taking care of Holy Kujo in Tokyo, while agents in Egypt discovered the existence of the Egypt 9 Glory Gods. They tended to the team's injuries at the end of their journey, most notably in helping revive Joseph Joestar.
In 1999, the Speedwagon Foundation led by Jotaro Kujo first escorted Joseph Joestar to Morioh and then were given the Bow and Arrow for study and protection.
In 2011, the SPW Foundation provided a submarine for Jolyne Cujoh's escape from Green Dolphin Street Prison. After Jotaro Kujo was rendered comatose, the doctors of the foundation tended to his body and cooperated with Jolyne to retrieve her father's Stand and Memory Discs. They also threw a special spear toward the Kennedy Space Center, which combined with Ermes Costello's Kiss and enabled her and Jotaro Kujo to reach Enrico Pucci.
There are two known headquarters of the Speedwagon Foundation located in Washington, D.C. and Dallas, Texas. However, there are also smaller branches in Tokyo and Meguro, Japan.
Steel Ball Run Universe
Much like the Speedwagon Foundation in the previous arcs of JoJo's Bizarre Adventure, the Speedwagon Oil Company was founded by a risk-taking entrepreneur striking it rich by finding oil in America. Unlike the previous Speedwagon Foundation, the Speedwagon Oil Company has no connection to the Joestars except for helping to fund Steven Steel's Steel Ball Run race.
In JoJolion, Lucy Steel is a member specializing in botany and geomorphology. In 1901, she's shown in Morioh carrying a suitcase with the Speedwagon Foundation's logo. In 1941, she investigates Morioh once again.
