Just make sure to get there with a decent weapon, upgrades and ideally a health pack.
For specific tips, this one covers pretty much all of them:

Thanks for that.
I've managed to get past phase 2 and to about the half way point in phase 3 now (the three red wave ground pound part), but that does give me some good perspective.

I'm assuming your bringing lots of healing into the fight. If not - do so.

"Lots" is relative when you only have 2 consumable slots.
I've taken to save-scumming before bosses at this point, as "getting back to them" ends up being such a pain that "getting experience fighting them" isn't really possible.

Though I've really only had to use it to get past... Uh... Nemesis (I beat Hyperion's face in without any difficulty and got half way through Fractured Wastes that same run I finally beat Nemesis).

Although now that I'm in the Scar, I'm having to do it on basically every room. Pretty much any time a... *wiki* Typhonops shows up. I thought it was a boss at first, as the first time I encountered one is was in a room by itself.

The main issue I have when fighting them is that they will sprint-charge at me faster than I can react in order to melee-swipe me, which does basically "my health" in damage (plus knockdown that lasts quite some time, or about as long as it takes to reset for another attack).

I can't even rely on long range to deal with them as they move so fast they may as well be using "teleport (destination: my face)." That first fight was so bad that a couple of deaths I went "what the ♥♥♥♥ even hit me. There's only one enemy in this room and it's over there."

That said, more generally, "♥♥♥♥ this region and everything in it." Because JFC they move too fast.

i have done him 1. try xD i had some luck but yea he s not impossible heavy if u know how to dodge, but he tank a lot of dmg or i had a too weak weapon but yea after finish him u can skip this location anyway..

It seems to me that it's about defeating his phases as fast as possible, especially phase-2... Which simply translates to getting decent weapons and perks before you take him on -- i. e., exhausting the preceding biomes of everything they have to offer, and also some luck in what items you roll for the run.
