Uh, no.
Lobo has went through the sun before. He's went through blackholes...alot.
He doesn't need to breath or eat or any of that crap.
He could throw them into the sun easier than they could him.
He's as strong, if not stronger than Superman. He's as durable as Mindless Hulk and his healing is a bit better.
Remember, Lobo can regen limitless amounts of blood with his crazy healing factor. And since this is Classic Lobo with clones, he can't lose.
All the hulks die other than Mindless, in which the hundreds or thousands or more Lobos beat on him until he finally dies....because Mindless Hulk can't survive very long without banner.
Lobo wins....pretty much 9/10
