Here's a sprite for Arbok, from the Lopunny fan game. Arbok first appears as a Level 22 boss at the end of the Forest area, where the game begins. Afterward, Arbok can appear throughout the castle, where the majority of the game will be set, as minibosses, particularly in trap rooms. Being rather large snakes, one can coil Lopunny completely with Wrap. They also have access to Glare, Crunch, and other nasty moves depending on level.
