The Super Skrull in the comics had the powers of 4 heroes, in the tv series G'iah now has the powers of 22 super heroes (including a few of the most powerful Marvel super heroes we've seen up till now)
Again, and? The point is the priniciple is the same; you also keep going on about them being "so powerful", but ignore that invisible woman beats nearly everyone on that list, super skrull is supposed to be powerful.
Also it's 22 people, but many of them overlap, like cap and bucky are essentially the same powerset.
There's basically "strong" (strength/stamina/durability):
Korg, hulk, thanos, cull obsidian, captain america, winter soldier, drax, abomination, corvus glaive, valkyrie, proxima midnight, outrider, captain marvel, thor, frost beast, groot; those are all covered by the thing
Then there's the "stretch" power, which is just groot; Mr fantastic does this much better
Flight/levitation, captain marvel, ebony maw; same as torch and invisible woman
Telekinesis, ebony maw; invisible woman has got this covered
Energy blasts, captain marvel; torch is the equivalent here
Intangible/invisble: ghost; invisible woman has ghost completely beat here since she can just turn off ghost's invisibility
Touch telepathy/empathy: mantis; kl'rt had his own super skrull hypnosis, and no touch required.
Chitauri and gamora add nothing, since gamora's and the chitauri enhancements are cybernetic.
So that leaves this super skrull with a grand total of 2 abilities kl'rt didn't have (of course ignoring the amount of abilities invisible woman alone has):
Accelerated healing: extremis, hulk
Ice manipulation: frost beast
No lightning because Thor has that as his status as god.
Later super skrulls also showed having the combined abilities of more than 4 people, and in a way that it actually mattered, not like this super skrull where 80% of them are the same "big/strong".
