Spoilers for the Underground Trial

Drinking from the well is drinking from the Well. There's nothing suggests he has the power of both or that you can even drink different parts of it. It's well. You drink, you get power.

Statesman and Tyrant were equal in power when first meet the Praetorian. It's stated why Tyrant has gotten stronger since then, he's given himself over to the well. Belladonna is an exception due to Tyrant's actions because without Arachnos, she's unable to obtain her Primal version's power since she's neither Night Widow or ghost.

I hate to disagree, but there is nothing that says they are equal in power.

They are analogues, counter parts, and yes, they are similar, but that does not mean the same.

Synapse and Neuron for example. Neuron has done numerous experiments on himself to make himself faster and smarter. Synapse hasn't.

Maurader and Back Alley Brawler. Ok, except for a height difference, that one may not be a good example.

Statesman and Tyrant. Have you ever fought Tyrant and had him lay down a lightning attack like Statesy does?

No, they are evil / other counterparts that is all. Power levels are something else all together.

Neuron being the evil counterpart was simply more reckless and desperate and therefore performed the experiments on himself instead of having them forced him like Synapse. They both have super speed.

Tyrant is a standard mission, meant to be completed by anyone. He doesn't even seem to have Unstoppable. Until VEATs, Statesman was only found as an enemy in RV and the LRSF. Therefore, he was allowed to be overpowered, but in the Tyrant mission, he doesn't have Zeus' Lightning Bolt. Since GR, Tyrant's also been switched to Super Strength instead of Energy Melee.

Just a few small points:

Praetorians know Hami is alive. They have the sonic fences up to stop the Devouring Earth from getting in. They think that Cole just smacked him so hard that he was no longer a world-breaking threat.

As for Why Earth? I think it's because of Kheldians, honestly. I think some of the Nictus landed here more or less on accident, and the Peacebringers/Warshades followed them. The Battalion runs on Kheldians, so it seems obvious that they'd come to a place with a "Free Squid Buffet" sign lit up over it.

I also know the "enemy of my enemy" dealie in regards to throwing the Rikti at the Battalion, but really- who would go for that? Maybe news of the truth behind the war is hitting the Rikti homeworld, but it sure isn't hitting ours. Average Joe (the citizen, not the hero) still thinks of Rikti as invading monsters. How would it play if we went to a podium and said "Hey guys. *Another* dimension is about to invade us. And, also, some mean aliens are about to attack. But it's cool because those guys that killed your families and destroyed the city seven years ago are gonna come over and help. And I promise they won't kill you, because the war was actually caused by a robot. Funny story. So here we go, main portal that Omega Team died to close.... open sesame!"
