The Drain Deimos is the brother of the Brain Sucker. It will climb up the walls and pounce on you and will also slash at your legs. It's most powerful attack is when it gets on its hind legs and runs towards you from behind and sinks its claws in the back of your neck and drains the energy from you until you press and push the buttons rapidly. Use the same procedures for dealing with it as the Brain Sucker.
