I tried to find it in the net but I failed, so any one knows a fighter with a variable angle of incidence, that's when an a/c's wing can be tilted up and down to change the angle between it and the longitudinal axes.

The A-7 Corsair II doesn't have a variable incidence wing, but the F-8 (F8U) Crusader does. The first airplane, that I know of, that had a variable incidence wing was the Republic XF-91.
The XF-91 also had mixed power (jet and rocket), reverse taper of the wing (wider at the tip), and reverse wing thickness (thicker at the tip).
It was built in the days when wind tunnels could not accurately all the nuances of design details and no computers were available to perform accurate simulations. So you built an airplane and test flew it to see how various ideas worked out. The XF-91 was marginally supersonic with everything (jet and rocket engines) running.
There is an XF-91 (2 were built) at the Air Force Museum (yes, another plug for the museum )in Dayton, Ohio in the Research and Development Hangar.
