Fiction
Transformers vs. G.I. Joe
Aberneth and Thor FalkenHauser together led a raid on the home village of Laird Mac Cullen. Mac Cullen fell to their blades, only to be avenged by Cullen's younger brother; with the world's very first firearm, the boy killed FalkenHauser and scared the rest of the raiders into fleeing. Immediately after FalkenHauser had fallen, Aberneth retrieved his fallen comrade's mystical warhammer. He went on to settle among the Picts and give his name to the Scottish village of Abernethy, and his hammer became a family heirloom. Stick To Your Guns Because of Aberneth's actions, the hammer's magical powers were hidden and unknown for centuries, until it unexpectedly activated in the grasp of a descendant of FalkenHauser.

Transformers vs. G.I. Joe: The Movie

Aberneth was the only man to fight "alongside the old gods in their final terrible war". These apparently included Prowl and Wheeljack.
Notes
- Aberneth and FalkenHauser's co-leadership of the raid is an echo of how Hawk and Duke have both led the G.I. Joe team at different times and in different continuities.
