Hubcap's original bio described him as a friend to everyone, but trusted by no-one. He's something of a con artist, and has all the qualities needed for it - charm, wit, charisma and a smooth tongue.

Probably owing to his similarity to Cliffjumper and Bumblebee, Hubcap was never shown in the animated Transformers series; in particular, he was not present when the other Year 3 minibots (Pipes, Outback, Tailgate and Swerve) were introduced in the Five Faces Of Darkness episodes. However, some fans argue that he is the yellow robot shown fleetingly two frames in The Transformers: The Movie in a scene in which Daniel saves a number of Autobots from dropping into a giant smelting cauldron within Unicron. [citation needed] The Autobot shown is resembles Cliffjumper but is coloured yellow, which exactly describes Hubcap. However, it is much more likely that this was intended by the animators (who often mixed and matched the designs and color schemes of characters to achieve such an effect) to be a generic robot, and not Hubcap (who apparently never even had an animation model designed for the series)

Something about bumblebee repaints don't interest me, that's why i didnt get cliffjumper
