Temporal fusion bomb
From Tardis Wiki, the free Doctor Who reference
Temporal fusion bombs were a type of powerful temporal bomb. It was capable of destroying an entire star system (especially when linked to a time rift) and any survivors would have a partial existence. A temporal fusion bomb was used on the Keshkali Ring Worlds, possibly placed there by Humans. The surviving Keshkali would later try to destroy Earth with the Undertaker's Gift, another temporal fusion bomb. (TWN: The Undertaker's Gift)
