Okay, go time. I am a bit surprised that I'm the first one to include all three avatars in a list. In my opinion, they are easy auto-includes, so my first three positions are taken up by them. Having three defenders who are able to bend all four elements and the ability to go into the Avatar state is too good to pass up.
- Kyoshi → If I could only have a single defender, Kyoshi would be the way to go. I believe her to be the strongest iteration of the Avatar. Her separating the Kyoshi peninsula from the mainland is the single most impressive demonstration of bending ever depicted throughout the series. Moreover, she didn't even seem all that taxed while performing the feat; so it is reasonable to assume that it isn't even close to the peak of her abilities. Absolute raw power. Additionally, she is shown to have much more of a warrior's mindset as compared to Aang or Roku.
- Roku → While I believe Aang will eventually overtake him in terms of power, we never get to see Aang in his prime during the show. That means that for the context of this discussion, Roku is the second strongest character and as such, he is my second choice.
- Aang → While he is often a goofy kid, Aang's powers are not to be underestimated, especially by show's end. Most importantly though, he is a one man army when entering the Avatar state. In his Avatar state, we see him defeat the fire nation armada in a matter of minutes. We also see him defeat a Sozin's comet powered up Ozai. Easy choice.
With my first three picks, I think I have the three strongest characters on the board and a monopoly in terms of both air bending and the avatar state. Moving on, the next choice is a very simple one...
- Iroh → Iroh uniquely gives you a bit of everything. Firstly, he is one of the strongest characters in the show. Avatars aside, he would likely be favoured against just about every other combatant. Secondly, he is wise, savvy and an experienced general. The man has seen and survived war. As a bender, he is one of the few characters (alongside Aang and Zuko) who learned the purest form of fire bending directly from the dragons. He also uniquely provides your team a morale boost. It doesn't end there though, as he also brings two important skills to your team. He is one of three characters that have been shown to lightning bend (Iroh, Ozai, Azula) and one of three characters that can re-direct lightning (Iroh, Aang, Zuko)... he is also the only character shown to be able to do both! Lastly, after my team thumps the opposition, I can sit down with Iroh and have a nice cup of tea. Iroh is the jack of all trades, master of all.
Continuing my list, it would be easy to simply select the very strongest characters, but I've decided it is better to round out my roster in terms of secondary abilities. Luckily I don't have to sacrifice too much raw power to do so.
- Toph → Toph is an exceptional combatant, but she also brings two completely unique skills to the table. The first (and more important of the two) is her seismic sense, her ability to "see" with earth bending. What good is it to have the strongest team if the opposition secures the victory by stealthily taking me out before my team has had a chance to respond? With Toph in our group, potential ambushes are neutralized before they can be enacted. She can detect the otherwise hidden approach of enemies before anybody else can (as demonstrated by her ability to "see" ants scuttling across the grass in the dead of night). The only characters that could circumvent this ability would be skilled air benders, and I already have all three on my team. Her second unique skill is her ability to metal bend. With a town nearby, there will be metal that she can utilize for this purpose.
- Katara → Katara is also an extremely powerful character and one of the best water benders. However, once again it is her secondary skill that I am most interested in. The secondary skill in question is not her healing, which I feel will have limited use in such an engagement (as many encounters will be straight up lethal and she needs sufficient down time in safety to implement them anyways). While her healing is a nice perk, I have chosen her due to her bloodbending ability. As it stands there are two bloodbenders among the field, Katara and Hama. I believe it to be critical to at least have one of these two practitioners on my side. While the feat can only be achieved during a full moon (at least during the ATLA timeline, S1 Korra is a different case), it is an absolute game changer. The chance of having a night with a full moon is only about 1 in 30, but if it does occur and you have two bloodbenders standing against your team, it could be game over right there and then. Bloodbending is devastatingly effective, difficult to counter and very unexpected. Most characters have no experience with it and it can cripple the very best of fighters. I actually think it was one of the few missteps the show ever made, but that is a different story. So with my last choice, I take Katara as she was able to overcome Hama's bloodbending and beat her at her own game. Katara is also generally a stronger water bender, has healing and is physically superior.
So there you have it, my list:
- Kyoshi [master of all 4 elements, strongest character, avatar state, warrior's mindset]
- Roku [master of all 4 elements, second strongest character, avatar state]
- Aang [master of all 4 elements, third strongest character, avatar state]
- Iroh [the most well-rounded fire bender, lightning bending, lightning redirect, wisdom, experience, morale boost]
- Toph [one of the best earth benders, seismic sense/sight, metal bending]
- Katara [one of the best water benders, bloodbending, healing]
I do hate leaving Combustion Man on the enemy's side, as his ability is very strong, unorthodox and has great range. That said, my team is easily strong enough to take him out.
Alternative list. Here is a secondary list I came up with. This one is based purely on obtaining a monopoly (or near monopoly) on what I feel is the actual strongest element in a real scenario (bloodbending aside), earth bending. As it stands, there are only 6 earth benders among the group of characters we can select from: Kyoshi, Roku. Aang, Toph, Bumi and the Boulder.
The strategy is simple. Find the biggest hill available in the combat area and use it to create an unbreachable fort. Simply have your earth benders take you to the very center of the hill, creating a closed off cavern (periodically opened up for air) that is protected from all sides. Now, none of the other characters (except one, we'll get to that later) can get to you in any reasonable time frame. If they try to burrow their way to your defensive position, it would be suicide for them as your earth benders could easily close them off and kill them. If they try to starve/thirst you out, your team can go out and fight them just as they normally would, but you'd be completely safe during the battle. I did mention that there is one character who could potentially beat your defenses ... Combustion man. We've seen his focused attack cut through solid rock with extraordinary ease and speed. As such, I break my monopoly by trading one of my 6 earth benders for him. Which earth bender?... Easy, the Boulder. The Boulder is the dumbest character of the twenty, the weakest earth bender of the six and essentially comedic relief in the show. Now, as soon as my team is set, priority one is to assassinate the Boulder. Shouldn't be too hard as he is of low intelligence and I have 3 avatars, the two best earth benders and the ultimate sniper... Combustion man. So there it is, my alternative list (obviously I prefer my primary list detailed above):
- Kyoshi
- Roku
- Aang
- Toph
- Bumi
- Combustion man
