Jump Joint

The Jump Joint is a bar in Kaon on Cybertron. Slinger works there.

IDW Generation 1 continuity
Some time before Cybertron broke out into full-blown war, Megatron invited Autobot captain Orion Pax to the Jump Joint (that is, he forced him to come by holding Bumblebee at gunpoint) for a peaceful chat. Orion only listened to him long enough for Autobot reinforcements to arrive and rescue Bumblebee by busting in through the bar's walls, floor and ceiling.
