|Toy Appearance(s):||Trapped by Arachnoid|
|Cartoon Appearance(s):||Along Came Arachnoid|
|Weapons:|| Protein Processor|
|Voiced By:||Rene Auberjonois|
A four-armed spider creature, Arachnoid resides in a dark, dank lair with webs covering the entire area. His uses his protein processor to feed his creation, Creep, any unsuspecting victims. Once Max is teleported inside, Arachnoid tries to catch him in his webs, but Max is able to escape. He destroys the protein processor, which destroys Arachnoid's lair and presumably kills him and Creep.
Though Arachnoid himself was presumably killed when the building exploded, his giant spider appears in the last two episodes and kills Norman.
