Thoughts
HOLY POOP. Lot to unpack. Going one by one team,
1933: heavy hitters with strength and good armor. These guys will be dominating a large portion of the fight, especially the Brontosaur. However, I am comparing them to how Kong's attack affects them, I have no reference for other attacks.
Chances of winning: 7/10.
1976: At first, I discounted the snake because it got torn apart by Kong. Then I realized it was torn apart by and restrained King Kong, one of the strongest monsters out there. That snake will be murdered, probably by a jaw crunch, but it's gonna do some damage before it does.
Chances: 7/10.
2005: Very strong again but with less defense. The glass canons of the team .
Chances:5/10
2017: The speed and intellect of the Skullcrawlers, the jumps and razor legs of the Longlegs, and the zerg rush of the Leafwings mean this team has a great chance.
Chances: 8/10.
So, I'm leaning towards either the Brontosaur, the Carnosaur, the Python, or the Skullcrawlers. If I had to pick one, I choose the Brontosaur for it's size defense and quick bites causing serious damage (as the 25 Lost World showed)
So, am I right or does one of the other teams take it?
