Ok, i never read Earth 2.
I like both, but the second one is better.
Probably Mister Terrific, you could learn a lot from him and in general i got a feeling he could explain stuff better than other "smart" people. I hope i don't waste to much of his time, but that can't be said about every Hero i guess.
Wait a minute since when is Hawkgirl Hispanic? My vote goes to Blue Beatle, close second Bane.
He is in my top 10 favourit DC Characters
I like all of them, but my personal favourite from those is probably guy gardner. I hope the get his portrayal right, he is usually a fun character in the comics.
Catman
Its probably Infinity Crisis, mostly because of Nostalgia, it (and the follow up 52) was the reason i became a DC fan in the first place. A close second place goes to Crisis on Infinity Worlds
^ its a reference to Flashpoint ;-D
Its probably one of my favourite Storylines in Comics and turned me from a casual fan in to a more serious reader. Before i only knew famous character like Batman and Superman and i knew the Titans because of the Teen Titans series (one of the main reason i picked up the one of the issue's was because starfire was on the cover, but i was so intrigued that i got all of the remaining issue's) and it turned me into a fan of Booster Gold, Animal Man, Lobo, Elongated Man, Black Adam (because of him i got the JSA follow up, and they become one of my favourite teams), Steel, The Metal Men and The Questions.
"Your Mom"
I never read a stand alone Dr. fate Comic (technical i read the weird 90 Run, but i don't count that), but he was a fun character in JSA, and besides Dr. Fate, there are all kind of magic stuff happening in that book, the fight against Mordru, Johnny Sorrow/ the king of tears and Eclipso.
@Lagvaldemag thats right, i forgot about Max Mercury.
Im not sure when Quick Silver was createt, my guess would be mid 1960, but it dosent mater the first flash was created in 1940, even if you mean the second flash he was created 1956.
EDIT: I Looked it up: Quick Silver was created in 1964, 8 years after the second and more well known character. And i found another Marvel character that was pre-dates Quicksilver, the Whizzer (Robert Frank), but even he was created in 1941 on year after the original Flash. https://marvel.fandom.com/wiki/Robert_Frank_(Earth-616)
Thanks @BobRossTime
Where was that originally printed?
Cyborg is always a Titan in my opinion. And if the need a black tech guy, Steel was a longtime member of the JLA. And don't get me wrong i like him in the Doom Patrol Show, but his story is similar to Robotman, i would prefer Beastboy in the team, it would fit better, Beast Boy was part of the Doom Patrol before he was a Titan.
Definitely Martian Manhunter. Cyborg was always more a Titans Character in my opinion, and i have a feeling the only reason he is pushed so hard into the spotlight is because of his skinn colour, for the diversity bonus. Which is kind of sad, there was already a Black Man who is a tech expert that was a member of the JLA: Steel, but DC ignores him. Don't get me wrong i like Cyborg, but for me he always a Titans character and he doesn't fit on the JLA.
My vote goes to Trigon, a evil demonic being that wants to destoy the world and that lives beyond time and space, a close second goes to Darkseid, he is also beyond time and space but he is less destructive.
Btw, not on the list but also scary a.f.: Lady Stix, also a immortal being from beyond space and time that combines the freaky demonic design and mindless destruction from Trigon and the enslavement and conquest from Darkseid.
My vote goes to Cyborg-superman, in my opinion a kind of underrated villain, he almost indestructible and always a potential danger in the background. But im kind of biased towards him, i grew up with the post Death and Return of Superman storyline
