"My skin darkened to a glistening black, and waves of coarse dark hair swept down my body. I was Big Jim."

Big Jim is a Silverback gorilla housed in The Gardens and acquired by Marco as his main battle morph.


"Big Jim was definitely big. He had fingers the size of my wrist. But Jim didn't seem to mind us being there. Mostly he seemed interested in Marco's apple. He looked Marco over, snorted like he wasn't impressed, and then held out his hand."

Big Jim is an adult Silverback gorilla who was transferred from another zoo to an exhibit at The Gardens[1] in California.[2] In 1997,[3] when the Animorphs intially entered The Gardens to acquire battle morphs to attack the Yeerk pool, Big Jim was acquired by Marco. Big Jim was Marco's very first morph, and became his primary battle morph.[1]

Three years later,[4] when the Animorphs began recruiting Auxiliary Animorphs, one of the new recruits also acquired a gorilla morph from the Gardens; it is unknown whether this gorilla was Big Jim or not.[5]
