Cell

Cells are a card type that were first introduced in DMR-01 Episode 1: First Contact.

Details
They are considered to be the parts that make up a creature.

Currently, they always have the special type of Psychic or Dragheart, and begin the game in your hyperspatial zone instead of your deck.

Unlike the other card types, it doesn't have other characteristics, and there is nothing to distinguish between the faces of the cell.

This card type is not printed on a card, and is only referred to for use by other abilities such as Psychic Link or Super Dragsolution. These abilities allow you to combine multiple creatures and flip them over into a single creature. Unlike the cells themselves, creatures made by the cell-to-cell links can differ in card types and have characteristics such as a Card Name, an Ability or Cost.

Rulings
The cell has no characteristics, other than that it is a spell. Therefore it has no card name, cost or ability. Originally it had a civilization, but this was changed.
 * Even if Universe Lapia is in the battle zone which gives the Phoenix race to each card, it can't give a subtype to a cell. However, after the Psychic Link, the race can be added to the Psychic Creature. This is also true for All Over The World, Supreme True Dragon Soul after the Super Dragsolution has been completed.

Card Removal cards that target "cards" instead of "creatures" such as Lance of Tonginus can be effective against cells. After a single cell card has been removed from the battle zone, the rest of the card can't stay in the battle zone in an incomplete form, so the remainder of the cards must be removed.
