My favourite scenarios are simple and you just roll a die to decide what happens...nothing crazy or hard to keep track of...so here it is...

1 - choose 1 character other than Punisher and consider them KO'd (Micro shot)
2 - choose 1 opposing character and consider them KO'd, then give the Punisher 1 penetrating damage (Punisher KOs undercover agent)
3 - choose 1 opposing character and they are considered to have Battle Fury for the duration of the game (Loony Bin Jim)
4 - choose 1 opposing character. They must take 1 penetrating damage per turn until KO'd. (Jigsaw burned to death...slowly)
5 - choose 1 friendly character, they always have Ranged Combat Expert (Punisher's aim)
6 - choose 1 friendly character and they always have Close Combat Expert (Punisher's fighting skills)

Then I even made an alternate one...

1- choose 2 opposing characters, when they’re adjacent give them both +1 to all their stats, ignoring the rule of 3. (Looney Bin Jim and Jigsaw team up)
2 – All Punishers are always Stealth. (Punisher on the job)
3 – All Punishers can always move 6 squares before attacking. (Punisher coming from nowhere at people)
4 – choose 1 friendly character, when adjacent to Punisher, Punisher receives +1 to all his stats ignoring the rule of 3. (Micro helps)
5 – choose 1 opposing character, they are dealt 3 penetrating damage and now have Leadership (creation of Jigsaw)
6 – choose 1 friendly character, they can use Close Combat Expert or Ranged Combat Expert at will (Punisher’s skills)

what do you think?
