[Pokemon] What is the most dangerous region?

What region in the Pokemon franchise is the most danerous? Which has the harshest weather conditions, the most dangerous Pokemon and the biggest roadblocks to overcome?

Unova, Sinnoh, or Galar are probably the most dangerous.

Kanto and Johto are temperate territories where the most extreme areas are well maintained forests and caves.  Johto's most powerful pokemon aren't a threat to people - Lugia hides in a cave beneath the sea, Ho-Oh is almost never seen, and the legendary beasts run away instead of attack people.  Kanto's also largely stay out of the way - Articuno and Zapdos are in abandoned places and Moltres nests where only the most powerful trainers are allowed.  Mewtwo, however, is a threat. Though he's also hidden away.

Alola is a tropical paradise with essentially no threats until the UBs appear.  

Kalos is a very temperate place as well, no real threats.

Hoenn is a nice semi-tropical island.  There's a giant volcano and a desert and some rapid waters though that make it a bit more dangerous than Kanto/Johto.  It's legendaries are all sealed away without the events of the game unsealing them, so they aren't a threat.  

Sinnoh gets incredibly cold.  It has a giant mountain range that bisects the region, making transportation across it require you to enter these dangerous areas.  The biggest natural threat is freezing to death in the north and dangers in the mountains.  Stark Mountain in the northern island is also dangerous.  The biggest *unnatural* threat is the legendaries.  Unlike the other regions - Sinnoh's legendaries are THREATS.  Palkia, Dialga, and Giratina can *unmake reality*.  They require the red chain, but that's not *that* hard to make.

Unova just has quite a bit of dangerous territory - a large desert, icy regions, and mountains.  Their legendaries are also the most active in the wild, with Kyurem being a legitimate threat to the public.  The wild pokemon are also very high level here and can attack much weaker trainers.

Galar is largely very safe.  But there is one GIANT danger.  The Wild Area.  It's almost entirely unmaintained and VERY powerful pokemon can chase down and attack weaker trainers.  Dynamaxing also lets Godzilla size pokemon fuck around here.
