Is there a adjective for someone with high pain tolerance? [closed]

Your character is stoic:

not affected by or showing passion or feeling.
especially : firmly restraining response to pain or distress —MW

For example:

It's been a mystery why some people can withstand pain better than others. —Genes May Help Determine Your Pain Threshold

It's a simple word, but tough: capable of tolerating extreme strain, hardship, or severe labor.

Tough is especially applicable in a character description.
