Zaxx
From Tardis Wiki, the free Doctor Who reference
Zaxx was a terraformer in the 25th century who worked under Professor Spector.
He had previously been a designer, but had been reassigned to biosphere analysis after a flaw in his fjord design caused the loss of a few miles of coastline. On Isen VI, he and his robot assistant Clive were sent to investigate irregular seismic activity in sector 42, where he discovered a lava pool where a lagoon had been. Clive, now under the control of Rann-Korr, refused to let Zaxx back in their ship, and the lava formed tendrils which grabbed him and pulled him under, killing him. (COMIC: Terrorformer)
