Lawrence Dawson

Origin
Lawrence Dawson lived his entire life with debilitating brittle bones. This turns his personality dour. When Doctor Boyle successfully treats Dawson, Dawson discovers he has plasticine stretching abilities to stretch and contort.

Dawson murders Boyle by strangling him with his elongated hands. He discovers returning to normal form is difficult, so he seeks out the assistance of the noted scientist, Doctor Harrell. While Harrell is trying to treat him, Dawson finds out Harrell knows about Doctor Boyle's work on Dawson, which could lead to Harrell figuring out Dawson was Boyle's murderer.

Dawson kills Doctor Harrell as well and flees to his apartment. The police find Doctor Boyle's appointment book with Dawson's appointment listed.

Pursued by the law to his apartment, Lawrence Dawson refuses to come out. When the police enter, they find him melting.
