Of course you can. But you got my point. The game starts with you escaping an mindflayer spelljammer ship who fought an draconic army.
And what did our level 1 character fight? Some imps. Two or three intellect devourers. Even if you exploit barrelmancy to kill the mindflayer and cambion more turn up pretty much requiring you to flee; and you get no XP for that, so short of curiosity one time, there is no reason at all to do it. Then we don't so much escape the ship as fall out of it. To be honest I find that entire scenario more beleivable than managing to escape Irenicus' dungeon at the start of BG2...
Having only this weaklings on this location makes no sense IMO.
And I play D&D to fight epic creatures like dragons, cast powerful spells like stop time, Dungeons & Kobolds is a pretty boring game IMO.
Piccolo blew up the moon before Dragon Ball Z even started. It kept trying to "raise the bar" with every new arc in DBZ, and it got silly rather quickly. I still like DBZ, but this is something it struggled with and where turning super saiyan would be a big deal at the end of the Frieza saga, skip forward a bit and Goten/Trunks are turning super saiyan as children with barely any effort just so they can keep up with the constant escalation..
There are a huge difference between DBZ and D&D. On DBZ, you have no limitations. On D&D, even the strongest archamge can only cast tier 9 spells. Teh strongest creatures are like Terrasques, Kraken, Liches and so on. And you can have CR 20+ creatures being a local threat. For eg, a Kraken(CR 23 on 5e) threatening a city who depends on his port and naval trade to survive is a plausible problem. Sadly, 5e DM guide and the AWFUL tier of characters implies that a kraken needs to be fought by "heroes of the world" and thanks to the awful tier system, a lot of people ignore that even a Terrasque can be a local threat.
5e doesn't have epic levels nor rules for divine ranks. The unique way to make a demilich a cannon fodder to your players is turning then into deities.
