Here was my idea for Revan. Has been a work in progress and changed slightly over time but the idea was to have him have a sort of synergy based on his allies and to show how he both received and gave benefits to all of his allies whether they were light or dark side.
Revan
Power: 9575 Health: 20,160 Speed: 135 Max Damage: 5150

Force Enlightenment (Special): Revan focuses on the force, using it to grant himself and all allies Advantage for 2 turns, Defense Up for 2 turns and 35% turn meter. All light side allies also gain Foresight for 2 turns. All dark side allies also gain retribution for 2 turns. 4 Turn Cooldown.
The Force Unleashed (Special): Revan attunes himself with both the Light & Dark side of the force, drawing on his allies to assault the enemy dealing special damage to all enemies. If the majority of Revans allies are light side, also dispell all buffs from all enemies and grant those buffs to Revans allies for 1 Turn. If the majority of Revans allies are dark side inflict a Damage over time effect to each enemy with an additional DoT inflicted for each enemy critically hit. If there are equal Light & Dark Side allies, both effects occur. (Zeta'd) 5 Turn Cooldown.
Charisma of the Force (Leader): All light side allies gain +30% max health and recover 5% of their max protection each time they use a special ability.

Balance of the Force (Unique): At the end of his turn Revan has a 50% chance to gain Foresight and a Heal over Time for 1 turn. If he does not gain Foresight and the HoT then he gains Retribution and Offense Up for 1 turn instead.
