Is it coincidence that the ugliest, least appealing, grotesque Pokemon are typically the best?

Here are the most disgusting unaesthetic Pokemon:

Landorus
Tornadus
Thundurus
Landorus-T
Thundurus-T
All "Ultra Beasts"
Incineroar
Vespiquen
Garchomp (WTF)
Jynx
Magmar line
Heatran
Rillaboom
Galar fossils
Many more...

By coincidence, these just so happen to be the most viable? I don't buy it. I think GameFreak force ugly shit on people with good stats and abilities to force you to use them. They know people will want to use the pretty things anyway.

Ugliest Pokemon ever? Crabominable. Just for the record.
