Martian Manhunter/Blackest Night

Blackest Night Martian Manhunter is a unique character who shifts between different forms periodically, giving him different options and strengths at different times.

Strategy
The DEFENSE buff is always up first, and for the first time, it only lasts 3 seconds. It is followed by the LIFE DRAIN buff, which lasts 6 seconds. Finally, his last buff, POWER GENERATION, allows him to generate power at a faster rate, and lasts 14 seconds. It would then cycle back to the DEFENSE buff - this time and after, it will last 14 seconds as well. The timer only runs while tagged in.

Defense
Causes him to take 50% reduced damage from all sources, including Radiation, Batgirl/Cassandra Cain, The Joker/Insurgency and The Joker/Prime's passives.

This buff seems to take some time to "load" upon tag in and may not reduce immediate damage despite the buff being displayed.

Life Drain
Causes almost any damage dealt to the opponent heal his entire team for the same amount, including his Super Move. Damage over time effects (including the burning from The Ibistick) inflicted by teammates can be converted in healing if you tag in J'onn while it is still running and while his life drain buff is active. It will stack with the life drain from Gauntlets of Azrael.

It is easy to miss this buff, as it only lasts for a few seconds and buffs can change during a special's animation. A super move may be a good idea if you can't afford to set up an unblocked special or the buff is about to wear off.
