Kirito and Mikasa are both worthless here. Kirito is only a combat badass in video games. Even if you gave him his video game stats, that's his SAO avatar, so he and and Mikasa are only good at close-range fighting, which every other character here does better than them anyway. He actually would have been more useful if they'd given him his ALO avatar. At least then his Spriggan illusion spells could have been used for support and he could fly. As it stands, Kirito's only value is if they need tech support or something (which makes him slightly more useful than Mikasa).
All that said, the Justice League hasn't used the Hall of Justice in ages. They either just curb-stomped the Super Friends (which would admittedly be kind of hilarious), or they fought some older version of the League without all the heavy hitters like the League's more recent rosters have. Also keep in mind that in a more realistic scenario the Martian Manhunter would have just mind-raped everybody on this team except maybe Saitama (we know telekinesis doesn't work on him that well, but we don't know if he's immune to telepathy).
You can't really blame them, given the prevalence of plagiarism.
But a lot of better artists don't put any tags on their works. Their unique style and attention to detail is what gives them fame, not an obnoxious signature listing all of their sites like an attention whore. And if you really don't want plagiarism, don't put your works online. Of course, artists who get all high and mighty and pissed off when people repost their works usually die out in obscurity since they won't be seen by the majority of viewers (and potentially future customers of their works). I mean, a single signature like a username is good enough. Any more is too much.
You forget animu. Be ready for every 12 yearold to show up and tell you to suck their dick because Goku/Naruto could solo the current JLA with both arms behind their backs because of MAH POWRLEVLS!
I tend to ignore arguments from people who can't actually explain why they think a certain character would win other than "because I think this character is cooler", so I don't fear those 12-year olds.
If anything they tend to make me laugh, like "Ha, ha, ha... wow, was I really this stupid when I was twelve? Man, maybe I should call my parents and apologize or something."
OmniGman said: Seriously though, they've dealt with potential universe-destroying threats before, so they have dealt with threats on Saitama's level. He'd kill a whole mess of them (maybe even all of them) if he bothered taking things seriously from the beginning, but in-character Saitama doesn't do that. We also don't know what his max speed is, just that guys who can move at mach speeds are snails to him. Flash can move at faster than light speeds and can steal speed from others to make them slower.
Didn't Saitama casually block & dodge Lightspeed Flash's attacks? Wouldn't that make him FTL? Also, what's this about Flash absorbing others speeds?
