I had a question about Normal mode. Does any enemy have more than 1 million health? Also, does any enemy do more than 50,000 damage in a single hit? If not, then in theory, wouldnt an Axton with Quick Charge and an op8 Impaler be literally invulnerable, if the Impaler had more than a million capacity? Yes, I know that ANY shield would make uou invulnerable, but still. Would it?
I have no idea about the actual numbers, but if you’re talking about taking a max level fully geared character back into normal mode, you’d be invincible even if you used only trash white rarity gear. Regular mobs wouldn’t even be able to break your shield. Even with a really crappy build, any character would be invincible. The skills you take wouldn’t make any difference. Maybe some of the raid bosses could still bring you down if you’re not careful enough, but you’d be able to kill them for a second wind pretty easily. That’s why people tell you to complete some of the challenges and farm for character skins in normal mode. There’s absolutely no risk of getting killed and you’d kill almost everything with a single shot.
I remember taking a high-level Maya back through The Beatdown on normal mode. This was way before the recent patch, and cloud-kill + kinetic reflection was knocking them dead left, right, and centre. At one point, I just stood there, let the idiots run up and take a shot at me, then watch while they and their comrades simply keeled over. It was hilarious!
The level differential alone would make your character basically invincible in Normal Mode. The same would hold true for TVHM. And as @anon13808724 mentioned, you could use White gear and still be fine. IIRC, my OP8 Siren can 1-shot Terramorphous in Normal (and likely TVHM though I haven’t tested it) using a [COLOR=DarkOrange]Bee[/COLOR] shield and his level is 50 (which is basically the cap for TVHM).

I’m wondering if Quickcharge Impaler would make you literally unkillable by everything except falling, though. Like mathmatexallyy, it would be impossible to die.
The only enemy that I can think of that could actually hurt you enough to take your shield down in NVHM would be Terra. That’s because he’s never below level 50 (or 52, or whatever his level is). Quick charge, Inertia (Maya) and Unstoppable force (Gaige) are similar to each other. They are also kill skills. Meaning that you’d have to get a kill to get them going. So, in that fight, I don’t think those skills would make the whole difference, and against the other enemies, you won’t need them at all. A level 80 Impaler will be quite sufficient! 
I can see it now:
Terra:
{Slap} Ow!
{Slap} Ow!
{Slap} Oh crap…
Isnt Terra only in TVHM and UVHM?
He’s in NVHM as well, and unlike other Raid Bosses he’s level 50 in NVHM.
