This unfortunately got put on hold due to life. This is very rough draft but atleast lays out an idea of the story spine.

Once upon a time two brothers are separated due to a dissagreement.

Everyday they remained distant and did not speak to or see one another.

Until one day, they are reunited on a military base and come to realize they are still at a disagreement.

Until one day, they discover a scientist injecting people with lizard DNA.

Because of that they are separated again. One is held captive and experimented on. The other is brainwashed and left in town with no memory.

Until finally, a flashback restores the brainwashed brother's memory.

The brother returns to base only to discover his brother was injected and turned into a lizard person as well.

And ever since then, they have stuck together to track down the scientist to gain the antidote.
