The Ambassadors were formed by Accord in order to carry out his long term plans to benefit humanity. All prospective Ambassadors were accomplished people who were tested by Accord and then brought on board by him. They are then given top tier cauldron vials, screened, and then have them administered. If they emerge unscathed they join the ambassadors ranks.
As a supervillian group operating within Boston, Massachusetts, they are collectively Accord's assistants and secretaries, they are almost unbeatable when Accord commands them directly in the field. They were colorful, tailored, thematic and gendered costumes with males wearing formal suits while females wear elegant if impractical dresses.
It seems that whenever Accord needs to replace one of his ambassadors he always tries to get one with a similar power to the one before. When he purchases Cauldron vials he asks for those of the same quality as his previous purchase. He does not recruit natural triggers, possibly because so few could meet his exacting standards.
They do not commit to impossible causes, unless forced to.
The ambassadors are essentially Accord's secretaries, assistants and errand people. They can be empowered to represent Accord in his dealings with different groups. They are also powerful combatants, each considered a major heavy hitter.
While in Boston The PRT largely left the Ambassadors alone as they kept the peace in the Cherleston area of Boston, Massachusetts. The organization was aware of Accords violent attitude however, and are essentially classified as a supervillain group.
After the Ambassadors arrived in Brockton Bay, Accord contacted Cauldron and requested five serums to give to his subordinates. Only four out of the five people he gave the serum to survive; Codex, Lizardtail, Ligeia, and Jacklight. Accord traded information with the Undersiders to get Tattletale to tell them what powers they had before sending them against the Teeth with the Undersiders in order to test these same powers.
↑ 1.01.1The Ambassadors Led by Accord, the Ambassadors hail from a smaller territory in Boston. Sporting tailored formalwear and ornate masks with brooches and pins rather than spandex and emblems, the Ambassadors are described a team of heavy hitters that even the Travelers weren’t keen on butting heads with. Led by a Thinker to organize them, they’re something of an elite force. After some losses at the hands of the Slaughterhouse Nine in Boston, they’ve come to Brockton Bay in hopes of joining the Undersider’s alliance. - Cast (in depth)
↑ 2.02.1And in each room were people in costume. Other teams had themes, natural or otherwise. Their costumes matched, or they unconsciously mirrored one another in style of dress or quality. Accord’s people were much the same, but it was very deliberate. Each wore fine clothing, elegant dresses and suits, and each had their hair neatly combed into place, oiled to the point that it looked wet. The ‘costumes’ were in the color of their chosen formal wear and badges or brooches they wore, as well as the finely crafted masks that hid any trace of their real expressions.
“You’re not expecting me to dress like them, are you?”
“No,” Accord said. “Truth be told, I fear you could never meet my standards, and I’m going to do my level best to ignore the fact that you exist. You’ll want to keep to the areas I designate and use the back ways out of the building, so that I never see you.” - Excerpt on Interlude 19.x
↑"You would have me risk good help on fruitless fights against immortal killing machines," Accord said. - Excerpt from Interlude 20
↑“Yes. We’re staying a little bit longer here. We looked into it, the heroes don’t have a strong presence here in your Charlestown territory. We can get away with just a little bit more.”
Accord looked down and corrected the position of the pen on his desk before turning back to Trickster. “Fifteen thousand dollars, and fifteen percent of any take. The heroes don’t have a strong presence here because they don’t need a strong presence here. I maintain the peace. It will cost me if I have people here, active and causing trouble.” - Excerpt from Migration 17.8
↑He’d taken the time one afternoon to solve world hunger. Six hours and twenty-six minutes with the internet and a phone on hand, and he’d been able to wrap his head around the key elements of the problem.
His boss had barely looked at the binder before calling it impossible, then demanded Accord return to work. A mind like his, in an office handling economic oversight within the PRT, looking for the precogs and thinkers who were trying to manipulate the markets to their own ends.
It was only one imbalance, one irregularity, but it had been an important one. It had nagged at him, demanded resolution. He had to prove it was possible.
Twenty-three years to see it all through. Twenty-three years to bring the world into order. Everything was a step towards those ends. - Excerpt from Interlude 20
↑“We lose nothing, and we gain time,” I said. “Which big guns do we have?”
"The Thanda. Cauldron has volunteered the services of their two elite members. The Las Vegas Capes offered help, as did the Ambassadors. The Alcott girl has her ability to foresee the future, but she’s trying to reduce the strain she experiences so she can offer more assistance at the most critical juncture.” - Excerpt from Sting 26.5
↑Accord was a thinker, and the running theory on his power was that he got naturally smarter as the problems he was addressing got more complex. It gave him an intuitive understanding of groupthink, politics, and convoluted designs. - Excerpt from Migration 17.8
↑“I wouldn’t normally share, but Accord told me I should disclose anyinformation you request. I attune areas to particular functions.”
“To what ends?” Grue asked.
“More gravity, less gravity, more intense temperature variation, less intense temperature variation. Friction, light intensity, the progression of time… More possibilities than I can count, many so minor you wouldn’t notice. But if someone powered is in the area, and I find the right attunement, as though I were searching a radio station, I can cut off their powers. If I’m exact enough, which never takes more than twenty or thirty seconds to narrow down, I can use my power to cancel out the filters that keep someone’s powers in their control. I can also remove the filters that keep their power from affecting them.” - Excerpt from Imago 21.4
↑“He has a mirror self,” she said. “Who walks in a world very similar to this one. This self has a limited ability to affect our world, and can’t be affected by us. Othello can push himself into that other world to bring his other self into ours, and vice versa. One leaves, the other enters. It looks very much like teleportation or invisibility. It isn’t.” - Excerpt from Imago 21.4
↑“Othello’s a stranger,” Tattletale said. “I’d think he has an imaginary friend who can mess around with us, but I didn’t see any sign of anyone invisible walking around.”
“Isn’t that the point?” Regent asked.
“No dust or glass being disturbed, none of that. I might think his ‘friend’ is invisible and intangible, but then what’s the point? Accord tends to have people with good powers. - Excerpt from Imago 21.1
↑Lizardtail’s power was pressing against me, even from the other side of the street. It penetrated my costume to the skin, making my skin tingle and ensuring that I was always aware of where he was. It was like the sensation of standing in front of a fire, just close enough to feel as though that heat had a physical form, just close enough to be bearable. It wasn’t hot, though. It was cold, if anything.
Lizardtail’s power pressed even harder against me. I could feel the edges of my injuries tingling, the wounds slowly knitting closed. Far slower than they should have been, given the earlier demonstration of Lizardtail’s power. Either he was weaker, or her ability to inflict wounds that progressively got worse over time was taking away from the power of his regeneration.
Butcher had a grip on Regent, threw him into Biter with enough strength to take the two of them out of the fight.
Possibly enough strength to kill one, if Lizardtail’s power wasn’t able to outpace the internal damage done. - Excerpt from Imago 21.6
↑Codex was a blaster-thinker hybrid. Tattletale had speculated that the woman caused permanent brain damage and memory loss , briefly augmenting her own processing power in exchange. - Excerpt from Imago 21.6
