#1 Wes
The most obvious of them all had to be Wes and Jen from the Time Force Team. She is an officer for the Time Force Police and tho Wes helped her unlock the Chrono Morphers by becoming the Red Ranger, Jen became the Pink Time Force Ranger and leader of the team. Same as Conner, Wes took some time to get traction as a leader but was still ultimately he still took a back seat to Jen.
How is it that you have the Quantum Ranger from Time Force, but NOT the Crimson Ranger from Ninja Storm?! Be consistent!!!!
