(Capcom's primary storyline)
The Connections is a crime syndicate involved in BC (Bio-Chemical) research, money laundering, murder and trafficking of weapons and drugs.
The Connections worked in collaboration with Albert Wesker's H.C.F. in 2000 in the creation of a revolutionary new fungus. They iterated through five lines of "subjects" capable of mind control, with each successive line given a letter-based designations. The early lines such as the A-Type had performance issues and were not considered practical; later lines improved upon their abilities and made them more practical as weapons. As of 2014, the most advanced series is the E-Type.
The goal of this organization was to use mind control as a weapon in itself, and planned to sell their child subjects to allow the takeover of regions without the use of more traditional bioweapons which could bring socio-economic problems as well as the needs of conventional weapons like nuclear, firearms or chemical weapons as well.
With the creation of the first E-Type, the E-001 (or "Eveline") in 2014, competing companies as well as others weapon manufacturers became seriously concerned of their survivability in the changing market since Eveline will become the seriously disruptive technology to render all forms of conventional weapon to become obsolete. The organization was forced to take Eveline into hiding after rival companies attempt to sabotage the operation to maintain competition in the market, transporting her on an LNG carrier to another lab. When the ship was attacked and the rogue Eveline found herself in Louisiana, the organization chose to allow her to continue living there and set up a lab in a salt mine, and providing Lucas Baker with suppressants to enlist him as an agent. Lucas kept in contact with the group, keeping them up to date with Eveline's condition while in hiding.
Prior to July 2017, they also created new variations of the Molded, the WM-001, its offspring the WM-001a, and the WM-002. It is unknown if these experiments were to create a new Series, or just to create new individual B.O.W.s.
