In-game, for gameplay, an excellent Widowmaker is the best in the list.
In the lore, the āstrongestā on paper should be Sigma, because he manipulates gravity; however, he is unstable himself (which could make that aspect even more dangerous than only if he was using that capacity in a perfectly controlled manner). Unfortunately for Sigma, heās being used and I feel like Sigma himself is too unstable to either be fully aware of it, or to sufficiently ācareā about it. He doesnāt seem to have any particular agenda on his own, with the sole exception of better understanding and manipulating gravity. Heās pretty much āon his ownā for the time being, while being used by Talon.
Reaper is for all intent and purposes a full āmeta humanā in the lore. He cannot die, probably cannot age anymore, can completely reshape his body into a āmistā or whatever that thing is, and pass through the smallest openings and cracks and so on. He literally teleports himself and āfeedsā on life essence to heal himself. The biggest downside to his powers I can imagine is that heāll outlive everyone, including all the organizations and the current events. I can totally see him wandering the world a thousand years after the events of OW in a completely different society.
Widowmaker, we know enough about her for now to know that sheās following Talon orders, at the very least (and, for now anyway). She seems to be āon a leashā so to speak. Especially in regards to Moira. It seems like Moira is her direct superior (not necessarily Talonās leader, but Moira has authority on Widowmaker and probably Reaper, too). Moiraās interactions with Widowmaker lead me to believe that rather easily. The one interaction where Moira remarks āIs that emotion I detect Lacroix?ā is a good one. Moira wouldnāt speak like that to Widowmaker if they had no link at all within the organization. It appears that Moira maybe have been the āmain scientistā at Talon responsible for ācreatingā Widowmaker (the scientist in charge at whatever Talon Labs where the experiments on AmĆ©lie Lacroix occurred). So Moira is able to, and allows herself the freedom to give remarks to a Talon agent like itās not a big deal at all. So for the moment, as long as Widowmaker ābelongsā to Talon (and Moira) she will keep following orders. For now Widow doesnāt seem to have her own motives and goals, only that she merely follows orders and is being sent on various missions for Talonās machinations. It may change in OW2, who knows, weāll see.
Doomfist is definitely aiming for leadership of Talon. I donāt think he is the actual Talon leader though. But I sure believe he wants that position. Iām almost certain that Doomfist will be one of the āmain villainsā in OW2ās campaign.
Sombraās Origin story reveal was clear, she wants to find who controls the world, and when she does, she wants to āpull the stringsā as she put it. A very ambitious goal to say the least. She wants to gradually and by āproxyā reach the very top; she wants to know who is behind the curtain prepping the show, and then manipulate them either directly or indirectly (by āpulling the stringsā, making them her puppets). I donāt see why she would manage to do that, because in the world of OW it looks like sheās absolutely not alone wanting something along the lines of ācontrolling the worldā one way or another. Sheāll have to first deal with Talon, then deal with the return of Overwatch as a functioning organization (since Winston confirms OW is ābackā and OW2ās story mode will focus on that for sure); and not to mention possibly having to deal with the new ongoing and rising Omnic Crisis 2.0, so if he wants to manipulate the whole show⦠sheāll have a lot of work to do, and sheāll put her life at risk doing so at every corner. Her own downside, I think, will be that she will need āfriendsā to achieve her goals, and one of them in the bunch is simply sooner or later going to backstab her, and sheāll find out the hard way Iām pretty sure.
As for Moira herself, well she does seem to be the main Talon ādocā, the āmad scientistā in charge of doing all sorts of experiments. The reality I think is that, for Moira, working āwithā (rather than āforā) Talon is merely beneficial for her research and experiments. I think itās a sort of mutual agreement thing without necessarily meaning that Moira couldnāt separate herself from them if she wanted to. I think that Talon needs her more than Moira needs them. But for now, it seems to work in her (and their) favor pretty much on a 50-50 basis. She comes up with all sorts of āfreaks of natureā so to speak, and some of those fit the bill perfectly for Talon as their new agents. As it is, in the end, I think that Talon basically finances Moiraās research, and in return Moira provides Talon with new products, so to speak. Iām not sure if Moira does have any long-term ambitions outside of just manipulating genes and the human body and mind; she doesnāt exactly strike me as the āI want to control the world!ā type of person. She seems too sophisticated of a āvillainā to be that type. She wouldnāt find a problem in creating a āpuppetā for herself I guess but then again I donāt think sheās the type of villain sending agents around the world to then eventually control everything. I think sheās just āfineā for now amusing herself and applying her scientific knowledge in her Labs thanks to Talonās financial and āmoralā support.
But yeah, in the game right now I think Widowmaker is the best if played well. Because Reaper⦠well, we know what happened to him recently. Doomfist is kinda hit or miss, he seems to be even more situational than Widow (gameplay-wise, and map-wise, too). Sigma actually feels clunky to play and thereās some obvious things that need to be addressed about him but the devs are too busy on OW2 development for now. And Moira is just not as good as either Ana or Baptise, period; heck Iād go with Mercy over Moira anyway.
