Thought this might be an interesting thought experiment. A couple of teams have to run the Helms Deep defence until reinforcements show up.
General Note: All prep time can also include venturing/scouting outside the castle gates to scout/assassinate/harass/etc the oncoming forces. All teams know that the army will arrive at the appointed time and they must hold the castle to the best of their ability. They know that reinforcements are on the way but they do not know when they will be arriving.
Scenario 1: Orcs Are A Cowardly And Superstitious Lot.
The united forces of the Batman Family have to hold the line!
Team: Batfamily
- Batman (Bruce Wayne)
- Robin (Damien Wayne)
- Nightwing (Dick Grayson)
- Batgirl (Barbara Gordon)
- Batwoman (Kate Kane)
- Black Bat (Cassandra Cain)
- Azrael (Jean Paul Valley)
- Huntress (Helena Bertinelli)
- Red Robin (Tim Drake)
- Spoiler (Stephanie Brown)
- Red Hood (Jason Todd)
- Alfred Pennyworth
Stipulations: The Bat Clan gets three days of prep time. They have all their normal gear, full utility belts and all weaponry and resources available in Helm's Deep itself. Alfred has a small workshop to whip up small scale variations on classic utility belt gear. He could, for example, make a batch of sonic grenades for each fighter but he only has three days before the siege begins in earnest. The team gets one Batmobile vehicle, it cannot be the flying variant.
Scenario 2: Lay Down Suppressing Fire!
A bunch of dudes with guns establish a kill box.
Team Guns!Guns!Guns!
- John Wick
- John Matrix
- John McClane
- Duke (Predator) and his crew
- Rambo
- Jason Bourne
- The Expendables (Full roster)
- Furiosa (Mad Max)
- Neo (Specifically from the lobby scene in the first Matrix film.)
- The Punisher (Netflix series)
Stipulations: The team get one day of strategy meeting and prep time. They all come with their standard gear with plenty of ammunition for guns but they do not have refills on any grenades or explosives. They also have all resources normally contained within Helm's Deep. Neo's powers do not grow beyond the point they were at in the lobby scene in the first Matrix film, he /does not/ have access to bullet time at this moment.
Scenario 3: Orcs Aren't Vampires But Close Enough!
A team of vampire hunters/fighters take on the orcish hordes!
Team Vampire Hunters:
- Buffy Summers (Buffy)
- Angel (Angel)
- Blade (Blade Movies)
- Trevor Belmont (Castlevania Netflx)
- Sypha Belnades (Castlevania Netflix)
- Van Helsing and Cog (Van Helsing film version)
- Jefferson Twilight (Venture Brothers)
- Selene (Underworld)
- Saya Otonashi (Blood: The Last Vampire)
- Marceline the Vampire Queen (Adventure Time)
Stipulations: The team get two days of strategy meeting and prep time. Buffy has her scythe, Trevor has the morning star from season two, Van Helsing is not infected with lycanthropy and Marceline does not have access to the cloud demon form she gained from the events of Stakes. Otherwise, everyone has their standard equipment plus whatever is in Helm's Deep. Cog has a small workshop and two days to make tools/gadgets for the squad.
Scenario 4: One, Two, Do the Kung Fu!
Weapons? We don't need weapons. We ARE weapons!
Team Kung Fu:
- Shang Chi
- Richard Dragon
- Lady Shiva
- Bronze Tiger
- Constantine Drakkon
- Bride of Nine Spiders
- Dog Brother #1
- Tiger's Beautiful Daughter
- Chinmi, Tantan and Shifan (Tekken Chinmi)
- Donut, Coolie and Tailor (Kung Fu Hustle)
- Baki Hanma (Circa the end of Search for Our Strongest Hero)
- Tokita Ohma (Kengan Asura)
- Masataka Takayanagi (Tenjou Tenge)
Stipulations: The team gets two weeks to train together /not in Helm's Deep/ and three days of prep time at the location. Baki is taken from the end of Search for Our Strongest Hero, Chinmi, Tantan and Shifan are all from the end of Tekken Chinmi Legends, Ohma is from his battle with Raion, Masataka has two biological hands but is otherwise from end of series. Everyone brings their own weapons plus there's whatever is in Helm's Deep itself.
Can these teams for it against the 10,000 orcs and all of their resources? Yes? No? How far do they get?
BONUS SCENARIO: PARTY MODE ENGAGED!
If no single team can do it then all four teams combine and have two weeks of training together elsewhere and four days or prep in situ. Can they do it as a full squad?
