Form Transformation is an ability to transform unique to Cell.
Cell's ability to transform is versatile and can be executed in several fashions:
- Cell naturally transforms from a larva to a pupa. He then naturally transforms from a pupa into his incomplete state—a process which requires him to burrow underground for approximately four years and then molt upon emergence.
- Cell can also forcibly regress from his incomplete state back into his larva form. This requires him, however, to naturally transform back into his incomplete state.
- After using his tail to absorb either No. 17 or No. 18, Cell's body undergoes a drastic transformation. In his incomplete stage, he will transform into his Second Form. In his second form, he will transform into his Developed Form.
Cell can be forced to regress form by having one of the Androids ejected from his body, thus causing him to revert to the previous form. This occurred when Son Gohan, as a Super Saiyan 2, knocked No. 18 out of him during the Cell Game. If, however, his body is destroyed and able to regenerate, he can regain his Developed Form, even absent the presence of No. 18.
