Peebo(Mk.3) - The basic Peebo, it serves the essential function of measuring people for 'badness' and 'going boom' on such evaluated 'bad guys'.
Peebochu - The first specialty model of Peebo to appear, Peebochu is, as its name suggests, capable of attacking with massive bolts of electricity. However, the model line seems a bit jinxed. Peebochu 1.0 was destroyed by a stray rocket at the Explorer's Society Banquet, while Peebochu 2.0, despite an upgraded hyperspace teleportation system for its personality and additional stealth systems, was skewered by the Knight Spectre, Rook before it could disable G'nolga. The third Peebochu is still active, although it hasn't hesitated to throw itself in the line of fire to protect Brianna.
Peebospy - 'A little bit country, a little bit rock and roll' according to descriptions, Peebospy is a dedicated surveillance Peebo with advanced cloaking capability and sensors.
Peebomag - An auxiliary unit to one of Brianna's many powered armors, Peebomag is outfitted with the traditional explosives, as well as anti-gravity movement and a tractor beam to bring along cargo(or passengers) that need to keep up with Brianna's powered flight.
Peebofox - A secondary spy model utilizing Brianna's advanced AI programming, and thus quirky and prone to pulling pranks.
