The Man of Tomorrow
From the sounds of it, i don't think Lobo could harm Thanos.
Your talking about a guy who Brawled in a straight fight with Odin (the Skyfather, not any shitty version). Tanked Galactus's full power, took a point blank shot from Beyonder (which Destroyed a City)
In the silver surfer comics, the same scenario was palyed out, Thano in his rage beat the crap out of the Silver Surfer with very little effort.
We are also taking about a guy who labotomized beyonder(another thing that couldn't die, Thanos delt with it) and has a Herald of Galactus as a slave. He also posseses very good teleportation technology if lobo starts cloning and he gets in a bad situation, he can port to another diamention to regroup and come up with a plan (Send his fleet to Destroy the Planet Lobo is on, then push him into a sun or something)
His teleporting abilitys can also target others not just himself, for instance when champion came back for revenege against thanos, thanos just teleported him to another dimention instead of dealing with him because he couldn't be asked with it.
