Octus is a member of the ruling Triumvirate who seized control of the Decepticons after the (second) death of Straxus. He is arrogant, lazy, and believes in a rather complacent method of Decepticon rule on Cybertron. Still, he can be pretty funny when he's poking fun at other Decepticon leaders.
Marvel UK comics continuity
An unspecified amount of time after the (second) death of Straxus, a triumvirate of Decepticons, ingeniously calling themselves the Triumvirate, came to power as the new rulers of Cybertron. Legonis, Octus and Seizer ruled together from their palace at the city Helex, sharing a three-seater throne. Octus had the center seat.
As rulers of Cybertron the Triumvirate were too lazy for active aggression against the Autobots. Instead they spent their time enjoying arena fights between Autobot prisoners and powerful Decepticon warriors (such as Quake), even contemplating pitting Decepticon against Decepticon should they run out of prisoners, rather than going out to get more.
When Straxus-Megatron (it's complicated) arrived on Cybertron with Ravage in tow, he was horrified with the state of things and challenged the Triumvirate's rule. Octus baited Megatron, calling him the Decepticon cause's "most celebrated LOONY!"
Legonis shoved Megatron into the area (of the arena), where cannon-boy bashed up a few Decepticons (including Quake, the schmuck) before making a speech about Decepticon values. Realising that they hated not going out and killing Autobots, the Decepticons turned on the Triumvirate for being lazy bozos.
- Octus (Octavius), Legonis (Lepidus) and Seizer (Caesar) were a parody of (or perhaps tribute to) the ruling Triumvirate of Rome after the death of Julius Caesar.
- Octus is pretty unique in form as a Transformer. He has a six-armed robot mode and transforms into... well, actually he never transforms in the fiction, but according to his co-creator Lee Sullivan his alt mode based on a pre-existing design. Sullivan had this to say in an email to the Obscure TF website:
- The design works well -- the Dalek's dome behind Octus' head, the infamous "dots" made up by his arms. His is a robot form setup not found on any other Transformer... so far, at least.
