John Aman is known both as Amazing Man and as The Green Mist, depending on who you ask, I guess. It would not be unsuitable for H&H Heroes to have more than one superhero name.
The Council uses a sleep-ray on John, I guess so he can't hear their deliberations. It seems to have a very short range, but is fairly portable.
Bereft of other weapons, John uses his teeth on a poisonous snake. Although biting is not a particularly effective attack, he might have buffed it up with Get Tough or a similar power.
The invisibility formula is like a potion meant to be taken intravenously. There is a side effect that not all invisibility potions have, but (as explained on the next page) the duration of this potion is a full week.
John finds his first clue, a monogrammed pencil -- with silver lead. I wonder if that would poke werewolves?
Also note that John has an airplane as a starting item. This is not commonly the case in H&H -- though an Editor could choose to hand out trophy items at the start of a campaign.
No real bearing on H&H, except for the idea that you could have Heroes run into poisonous pets.
