Cannonball's go-to move appears to turn on his blast field, then blitz his opponent. My opponent in previous rounds and the RT appear to peg him at building-busting levels of power, which isn't nearly enough to even harm my team.
Cannonball cannot even hurt me really, nor can he put down any of my team with just raw brute force.
Black Hand and Nekron are literally dead Black Lanterns who cannot die and recover from basically any damage
Zeref is completely immortal and unaging, and cannot die from anything that does not have power that comes from death
Simply hitting my team hard enough does not work, Cannonball does not even hit very hard.
Besides this, Nekron and Black Hand have the power to convert people who have died before into Black Lanterns. Given that Cannonball has died before, and that the BL rings sent out have nearly caught the Flash (who is quite fast), Cannonball instantly becomes a Black Lantern at match beginning.
Palpatine has three viable win conditions, none of them work.
Lightsabers
Force choke
Force lightning
Palpatine possesses no win conditions.
On top of this, [Palpatine has also died and been revived](), meaning similarly to Cannonball he can be instantly converted into a Black Lantern should the above not work.
Once he dies, he also becomes a Black Lantern.
Ultron's entire thing is just being a really strong brick. Ultron may be stronger than his past forms, but my opponent in previous rounds has argued he possesses weaponry he's had in past bodies when nothing actually indicates this, nor is it provable in any capacity. Additionally, he does not use more esoteric forms of damage in-character as his time as Ultron-20, resorting purely to beams/punching:
Even if Ultron did have sonics/electricity/etc. none of Ultron's weaponry would be effective against me.
Ultron does hit hard, sure, but refer to Point 1 as to why hitting hard does not necessitate victory against my team.
Additionally, Black Lantern Palpatine poses an immediate threat to Ultron. Ultron's internals are explicitly weak to heat and there is a fairly obvious opening to shove a nice hot lightsaber in. Besides this, Palpatine can use his Force mastery to manipulate Ultron's delicate inner circuitry, as was the argument to get him in tier for Magneto. Palpatine can and will pursue these options due to his notable intelligence and knowledge of Ultron's weaknesses.
So I've been laying out soft advantages of how my opponent's team turns into Black Lanterns and kills themselves but if that doesn't work here's the real stuff.
My team has a variety of means of instantly killing the opposition.
Black Hand can drain people's life forces near him without seemingly any sort of vector of attack and can also turn people nearby into undead
Nekron's lightning is capable of aging people to death rapidly on contact
Additionally, my team possesses other advantages readily apparent if the battle does not end instantly.
Cannonball is instantly converted into a Black Lantern
If this does not occur, Cannonball blasts towards my team
Palpatine may attempt a force choke/lightning blast
Ultron may attempt a blast
My team converges on Palpatine/Ultron
Palpatine/Ultron's close combat methods are useless against Black Lanterns/Zeref
Palpatine/Ultron cannot survive the death magic/life force/etc etc.
If combat does not immediately end, Zeref's death magic covers the entire battleground and kills everything alive
If my opponent survives this, Nekron and Zeref enact their universe busts over a longer period of time and kill everyone
