Refusian
From Tardis Wiki, the free Doctor Who reference
Refusians were the natives of Refusis II. They were peaceful and possessed superhuman strength. They had been made invisible due to solar flares. They welcomed the humans and Monoids to their planet, so long as they ceased to be in conflict with one another. When the First Doctor suddenly turned temporarily invisible, Steven Taylor thought that it was caused by contact with Refusians. (DW: The Ark)
