The fact that Gates Capa had a Hambrabi confirms that Paptimus exists in the GQuuuuuux universe...
i've only ever heard this, not seen it, so don't quote me on this: but apparently one of the producers for gqx said that paptimus just straight up does not exist in gqx. what does that mean? who knows. but at least machu and co have nothing to worry about for a bit.
