Going by his resistance to repulsors, energy weapons, and Firestar it's not going to be enough to vape him before he seeps into the ground like in Carnage USA and waits for Lucy to tire.
And this is of course assuming Cletus doesn't straight up blitz her before she meltsdown.
Death Battle did what it usually does. It tried to find some cool sounding factoid to put a character over to make themselves sound cool and in the know. So they brought up the Hiroshima feat while disregarding that you need a LOT more heat than that to stop Carnage. Their plan backfired, and exposed them as giant casuals that know little about comics.
