P.U.P. is a brick-built dog that uses different pieces colored in common shades amongst the Ultra Agents theme, such as Black, Dark Stone Grey and Transparent Light Blue. His body's front and back are built with torso pieces commonly seen in Battle Droids, connected by a robotic arm. His legs are made with four black robotic arms, mostly used on the Droideka and BIONICLE Minifigures. His head is built by a 2x1 plate with a claw in the end, a triangular, transparent piece, a transparent blue stud and a small 1x1 claw piece.
P.U.P. is the robot dog of the Ultra Agents, who is often used as a guide and tracker of the team.
Ultra Agents App
P.U.P.'s first appearance was in the Ultra Agents App, during Mission 6: Ultra Agents Mission HQ, where he was accompanying Solomon Blaze while riding the cab of the mobile HQ. He was the one who discovered the source of the virus that Terabyte has sent to Downtown. After Solomon left to investigate, P.U.P. stayed in the HQ with Caila Phoenix and Christina Hydron. He was also the one who discovered that someone was trying to teleport inside of their base. After the agents managed to prevent the villain from teleporting to their base, P.U.P. was seen with the others, being congratulated by Agent Blaze.
Ultra Agents: The AntiMatter Missions
P.U.P. reappeared in Ultra Agents: The Antimatter Missions, where he got a more prominent role.
In Mission 1: New Base, New Gear & New Enemies, P.U.P. was seen with all the other Ultra Agents in the newest HQ in the cargo bay (Excluding Jack Fury and Max Burns) where he leaded the way of Agent Steve Zeal to the super villains' cells at the HQ prison. He discovered one of Spyclops' Spyders in the floor of the prison, spying. P.U.P. managed to destroy it.
In Mission 3: Attack on Dr. Brainstein's Lab, P.U.P. sent a message to Solomon Blaze and Agent Curtis Bolt, who were capturing Toxikita after Professor Brainstein's sacrifice. Asking for reinforcements in the HQ, an image of P.U.P. appeared in the cab of the Stealth Patrol, with Caila Phoenix's voice in it, just before the image was cut down.
In Mission 4: The Trap is Sprung, P.U.P. barely appeared, as he just was seen after the communications were jammed by Invizable and when he closed the outer doors of the HQ, in an attempt of stop the freed super villains. After this, P.U.P. wasn't seen again.
- His appearance is similar to the K9-Bot from Space Police III.
- He is similar to AntiMatter, as both first appeared in the Ultra Agents App, in Mission 6: Ultra Agents Mission HQ and physically released during the Spring of 2015.
