Raven/Rebirth

Raven/Rebirth is a new character introduced in the 2.13 update.

Strategy
Combine her with other Rebirth characters and Crit Augments. On Tag in, she'd "drain"/siphon ALL of her opponent's power if it is more than her!

Good with

 * Other Rebirth characters: As stated above.
 * Hawkgirl/Prime: Hawkgirl's decreased tag cooldown allows Raven to tag in and steal power more often.
 * Wonder Woman/600: Her passive grants Raven 30% more damage and power generation.

Good against

 * Batman/Arkham Origins: Immediately tagging in whenever Batman tags in will completely nullify his passive.
 * Batgirl/Prime, Ra's al Ghul's Scimitar: Similar to above.

Countered by

 * Batman/Arkham Knight: Power drain & Crit immunity can render him completely immune to Raven's passive.
 * Green Lantern/Red Son, Static/Prime: Both can be immune to different parts of Raven's passive with Crit and Power Drain immunity, respectively.
 * LexCorp Set: With 2 LexCorp pieces equipped, one can completely reverse Raven's power drain.

Abilities
Her are Raven's abilities.

Trivia

 * The wording of her passive mistakenly refers to Energy when it actually is referring to Power. This was also a long-running problem for the passive of Superman/Man of Steel, although it was eventually fixed.
 * Due to many complaints regarding Raven's SP1 of having to swipe multiple times, the developers have decided to remove the multiple swiping on this version of Raven, so you'd only to have swipe once and she'd hit twice this time!
 * She's the only version of Raven to have a higher health stat than damage stat.
