Narrative:
After a normal preflight; we proceed to fuel 13;000 lbs of fuel and complete our normal routine. Everything was going normal until we start rotating the airplane; first we have anti-skid light inop on and auto brake light on at positive rate I try to rise the landing gear handle but it won't came up; we run the QRH I pull the trigger and rise the gear up. At 400 ft with the flaps up I try to engage vnav but was not working; at the same time auto throttle stop working even when the lever and light still on in sequence we lost N1 on #1 and #2 we also lost egt in both engines and trim failed light came on; first officer lost the command bars and auto pilot. At this point I believe I have an electric problem; so many faults at the same time.I take the decision to return to [the departure airport]; we was vector for the ILS runway xx; I prepared the plane for the approach run the proper check list and when we lowered the landing gear we have nose landing gear red light; right main landing gear red light and green left landing gear light we start running the check list for landing gear disagree; I requested a low pass by the tower to make sure I have gear down. At this moment my major concerns are the electrical; I fear an electric fire. I took the controls and landed safely. Before applying manual brakes; I feel the aircraft braking and when I brake it was more intense than my inputs. No thrust reverses.

Title: Flight Crew reported loss of electrical systems on takeoff resulted in multiple systems failures and an air turn back.
