Fear my name!

Once, he was known as Killswitch, but that was before this vicious Decepticon mastered all five of his terrifying alternate modes. Now, the Clan of Six has blessed him with a new name fitting for a mighty Six Changer like himself. The Autobots shall tremble before the wrath of Hexadeathimal!

Or rather, they would if it wasn't impossible to take him seriously with that name.

Notes

"Chaos will always triumph over order! It is the way of things."

• Killswitch is based on an unused Decepticon deco for Quickswitch that was first revealed to exist in Legacy: The Art of Transformers Packaging. His name was picked out for being similar to Quickswitch's in the same way that Greatshot's is similar to Sixshot's. As written, he wasn't intended to be the Decepticon Killswitch, who debuted in Ask Vector Prime, but the creator of that Killswitch thinks of it as a valid take on the same "archetype", so whether or not they can be considered the same "character" is down to whose authorial intent you give precedence.
• His Six Changer name is hilarious.
