Charlie (Show and Tell)

Charlie was a name accepted by boy from alien planet, after Jack O'Neill's son. Prior to this, he was called only as "Son" by his "mother".

He was created by his "mother", Reetou the invisible alien and given the ability to see those creatures. His purpose was to be a go-between and warn Tau'ri of Reetou Rebels and their plan to attack Earth.

Unfortunately for him, genetic engineering performed on him had many defects and his organs started to failing. After he completed his mission, he was taken by Tok'ra to their base and was supposed to blend with one of them as only one possible cure. Nothing was heard about him since then.
