Electro Bolt: Shocks enemies, stunning them temporarily. Shocked enemies are more vulnerable to melee attacks. If shot into water, any enemies in the water will be shocked, taking a lot of damage. When this plasmid is active, his hand convulses as electricity arks over it. A faint blue aura of ozone is also visible at his fingertips. Should he charge it up, it would produce a bolt of lightning that arcs between enemies, stunning them just as a normal bolt does.
Incinerate!: With a snap of his fingers, Delta can instantly engulf an enemy in flame, causing them to take damage over time. When this plasmid is active, his hand appears severely burnt, and flames sometimes appear between his fingers. Should he charge it, the engulfed enemy would also be at the center of a fiery explosion that may engulf other enemies.
Winter Blast: With a wave of his hand, the enemy in front of him is frozen in a thick layer of ice. An attack with sufficient power will shatter the victim. When this plasmid is active, Delta's hand appears frostbitten. Should he charge it, the victim will be frozen in a block of ice.
Hypnotize: Should the thrown polyp hit the enemy, it will fight for Delta for about a minute. When this plasmid is active, Delta's hand appears normal, but a red polyp grows from the palm of his hand that he can throw. Should he charge it, the enemy will fight for him for longer. However, victims whose wills are strong will not be affected by this (that means bosses and avatars). Examples of enemies that would be affected are Big Daddies (this includes Delta himself, so should he get hit with an enemy's Hypnotize plasmid, he will fight for them), Splicers, and other relatively weak enemies.
Insect Swarm: Should the thrown polyp hit the enemy, bees will swarm the victim. When this plasmid is active, his hand appears normal, but a green polyp grows from the palm of his hand.
Telekinesis: Allows him to pick up heavy objects from a distance and throw them. When active, gravitational distortions emanate from his hand.
Summon Eleanor: Should Delta and Eleanor become separated, using this plasmid can call her back to Delta.
