Song

General
Commodore Sujin Song is one of the three Nautilus Heroes, specializing in damage inhibition, reducing the damage dealt by enemy ships.

Advantages
Song's Active Power, Tactical Shift, reduces the damage of all enemy ships by 90%, allowing your ships to outperform the enemy, and destroy them with little damage dealt to your own ships.

Song's Passive Power boosts Rearguards and Dragoons, two ships who complement each other. One can multi target and the other can clean up once it passes behind it. The health boost she provides can help with this combo.

Song's charge rate is high enough where you can easily obtain two charges to use in battle.

Disadvantages
Song's Active Power is mostly situational, so if you have no ships left to deploy or have no enemy ships to face, the power would be wasted.

The Active Power only lasts for 15 seconds, which may or may not be enough time to destroy heavily armored ships, such as the Aegis or Ramshackle.

The Active Power may not be suitable against ships who have Melee damage listed in its DPS stats, as there's no explicit value given to be reduced.

Strategy
Song's damage inhibition can be a nasty counter to Super fleets, as the damage they can output can easily decimate enemy fleets and the Capital Ship. With the right ships and timing of Song's Active Power, one can easily destroy Super fleet formations and destroy the enemy's Capital Ship afterwards.
