GURPS Supertemps - Blockbuster

Blockbuster / Heavy Nova

(Harold Potter)

Main illustration : Blockbuster form.


This character is from a 1990 supplement for the GURPS tabletop role-playing game. IIRC it was part of the first iteration of the GURPS Super super-hero line.

So yeah, it’s all terribly obscure if you’re not a longtime super-hero RPG and/or GURPS enthusiast. Sorry about that, heh ?

Powers & Abilities

Harold has the ability to transform at will into either of two super-heroes:

  • The walking brick  known as Blockbuster.
  • The high-flying, fast talking Heavy Nova.

Blockbuster is a man of stone, much like the Thing or Blok.

Heavy Nova can fly and fire energy blasts.

Harold himself has only the minimum skills and abilities needed to graduate from the police academy.



Like most kids, Harold Potter had always dreamed he’d grow up to be a super-hero. But without any powers, that was impossible, so he applied to become a cop instead. He graduated at the bottom of his class, only to be shot on his first pursuit by an anonymous hardware store robber.

Harold then took the insurance money and started a private detective agency: Harold Potter, Private Investigations. The name attracted little attention, but eventually, a client did walk in. Unemployed actress Chloe Vanderlain needed her ex-husband found to collect back alimony.

Harold was unable to find any leads, but eventually Chloe’s ex finally paid up.

Harold again started dreaming of being a super-hero… until his dreams began turning up in the newspapers. At first he thought he was predicting these heroes’ exploits. But with Chloe’s help, he learned that he was subconsciously becoming two separate heroes: Blockbuster and Heavy Nova.

Harold figured out how to become each hero at will. Yet he was unable to control either of their actions except to revert to Harold Potter at will.

Harold hired himself out to Supertemps as manager to both his alter egos. In the meanwhile he continues operating his detective agency, now known as Truly Amazing Metahuman Investigations, Inc..


Harold is a geeky-looking 27 year old caucasian male of small build. He usually dresses in casual clothing.

Blockbuster is an overmuscled, cement-colored man in jeans, work boots and a loose vest.

Heavy Nova is a taller, acrobat-built man with a tight bodysuit with a star insignia and an ankle length cape.


Harold Potter is basically a nice guy who always tries to do what he believes to be right.

Blockbuster is a battle-happy brick. Once bystander are out of the way, he enjoys beating up those foes tough enough to take it.

Heavy Nova is a vain, flashy showoff. He prefers aerial combat and overbearing soliloquies.

Other Harry Potter Universe History

The GM will have to determine what impact, if any, Harold’s wizarding namesake will have on his career.

There are several possibilities:

  • The easiest is to simply ignore the coincidence and leave Harold as an “ordinary” super-hero. The GM could decide that Harry and his exploits are fiction even in Harold’s universe.
    This would lead to occasional confusion in some clients, unless they know about principles of magic that differ considerably from the Hogwarts variety.
  • If, on the other hand, the two Potters co-exist in the same universe, some of Harry’s less educated followers might still be confused, although Harold would be understandably curious about magic and his alter egos’ ability to deal with it. Some of the dumber Death Eaters might mistakenly report on Harold’s exploits instead of Harry’s, thus becoming snacks for Nagini.
  • On the other hand, a few dogfights between Heavy Nova and an occasional squadron of Death Eaters would likely make the muggle world forget about a measly Ford Anglia.
