Spectre is the equal to LT and Spectre has been put to shame by Lucifer Morningstar what could LT do that Spectre could not i say to you NOTHING even if he could he wouldnt be able to destroy Lucifer even a blast with the power to destroy a multiverse didnt even dent him one bit TOAA's powers were in THOTU which he let Thanos have in order to have Thanos kill himself instead of TOAA having to do it thus reparing the multiverse Thanos dispersed all his power when he remade the multiverse Lucifer would just have to join his brother to make a multiverse and even when Thanos destroyed the multiverse he couldnt hurt Adam Warlock because he was outside of the multiverse Lucifer Morningstar can also exist outside of the multiverse and beside that i dont think LT has the power to destroy the whole multiverse since when it was destroyed he went with it.
