Weasel

Rheaunalt Lensenbrink, better known as the Weasel, is a member of Solid Snake's support crew in Metal Gear: Ghost Babel. He is a mercenary said to be one of the most well known and resourceful in the world, who keeps himself informed about current mercenary activities around the globe thanks to his private connections. He earned the nickname "Weasel" due to his ferocity and cunningness, which he doesn't mind.

On 1997, he had participated in a war, in which his brother was killed (it is heavily suggested that he bore some responsibility for his brother's death).

During the Galuade incident, Weasel was working for Steve Gardner, the Deputy Director of Central Intelligence, to monitor Solid Snake and his support crew and eliminate anyone with knowledge of Gardner's involvement in Project Babel. Although, Weasel kills Brian McBride, he decides to spare Mei Ling and Roy Campbell after developing a friendship with them.
