Dober P.D. fills the niche of a tanky wave attacker. He has a very slow movement speed, but sports a massive health pool (800,000 at 100% strength magnification) and only 2 knockbacks, Dober's attacks are close-ranged area attacks (5,500 damage per attack at 100% strength magnification) and whenever he successfully hits an enemy he has a 33% chance to do a powerful Lv. 3 Shockwave. Overall, Dober P.D is a challenging enemy to defeat due to the lack of units specialized to deal with non-traited enemies.
Had 7 marriages and 52 times of capricious calendar.
Its colours is gray near black, but it isn't black.
Since he can use wave attacks, swarming him with close-ranged cats will negatively affect you. One way to defeat him is to build up 2 or 3 Bahamut Cats, supported by other strong cats, before reaching the enemy base.
Since Dober P.D is naturally slow, flinch and knockback effects are effective against him. Ururun may help with her occasional knockbacks, and the Sniper Cat power-up is recommended against him too.
Don't forget to bring Cats that can effect White Enemies (for example, Holy Valkyrie) or are immune to/negate shockwaves (for example, Anubis for immunity to shockwaves and Octopus for negating shockwaves) to fight Dober P.D.
With good protection, you can use Shadow Gao to quickly kill Dober P.D due to his massive damage against white enemies and his immunity to shock waves.
