Oiler

Oiler rolled onto the scene in 2003's Transformers: More Than Meets the Eye #4, a Modern Age entry into the sprawling, lore-rich universe that IDW and the More Than Meets the Eye guidebook series devoted themselves to cataloguing with such devotion. With appearances spread across the official guidebook and the Generation One companion material, Oiler is very much a character of the encyclopedic tradition — the kind of figure that dedicated Transformers fans and completionists treasure as proof of just how deep this mythology runs. Sharing pages with the likes of Over-Run, Rampage, Octopunch, Phaser, and Bristleback, Oiler exists in vivid, action-packed company. A rare find with only three catalog appearances, this is exactly the sort of character that makes digging through back issues so rewarding.
