Chris Beer

Chris Beer looks like an old-west giant of a farmhand, with broad shoulders and hips. He walks heavily and wears thick-soled boots, which disguise his most obvious physical adaptation to his horse DNA. His feet are very hoof-like and require the regular use of a farrier to keep them trimmed. His boots substitute for horseshoes, which Chris refuses to wear.

Chris touts long, wiry hair with the texture of a horse's mane. Before he speaks, he often clears his throat with a neighing sound. His thick vocal cords are responsible.

His usefulness in the Human-Hybrid Project is his ability to sleep standing up, even in a battle-type situation. 

We first meet Chris in Book 6 of The Human-Hybrid Project, Taking the Tower.
