first of all the bolded makes you look shockingly foolish. Braniac has assimilated and captured beings well beyond the scope of magneto and there is absolutely nothing magneto could do to stop BRANIAC. whats he gonna do? rip him to shreds? his program is down to a molecular level...he will infect magneto with cellular level coding and take him over, or simply capture him and put him in a container...he is well aware of magneto's full capabilities, i'm sure.
Loki being greater than Joker? man you've exposed yourself...is loki even a man?
Harley Quinn > Loki...BETARAY BILL > Loki
Ultron is a robot...Adam has the power of gods and would just shred ultron...zero comp....
You are misunderstanding and showing your ignorance on some of these match ups brehbreh, allow me to explain...
Magneto CAN and WOULD beat Brainiac due to a style match up. Literally every offensive option Brainiac has outside of assimilating him has an immediate counter from Erik AND Assimilation will go about as well as it does from the Phalanx. Magneto CONTROLS the electro-magnetic spectrum, he could literally wipe Brainiac's coding out, its something unique to Magneto and his abilities, which is why its not an option from Dr. Polaris in DC.
Loki would destroy Joker in a fight. This is not about a popularity contest, this is about a 1v1, Joker is outclassed. No polling results can save him here.
Ultron is a living AI program, he's Marvel's version of Brainiac to be honest. The difference is that Ultron has actually won and conquered the universe in separate realities
. He is also made out of Adamantium, Adam for all his strength, cannot break, shatter or bend Adamantium so he's basically fighting a swarm of unbreakable robots until they duplicate his SHAZAM call like the OMACs did and turn him human
.
But seriously, you could mix and match any of the 5 I named with the DC villians and Marvel is winning almost any encounter and Darkseid is stalemated/trumped by Thanos. This is not a contest, this is a conquest.
