As suggested by @toddumptious , here’s a thread for sharing arena - worthy creatures, and the portal addresses necessary to find them.
Some of the planets they’re on are a bit challenging. I accept no responsibility for death or mutilation.
These next two shots are not high-spec creatures - bu they are robots. And they’re fairly rare.
Fighting the locals is a fun way to discover whats in the area, I thought this opponent looked cool, and then I saw it wandering behind the Archive during battle. It had decent stats too.
There was a bat winged variant that I may go back and get, so I can have a devil/angel tag team.
These next two have good stats, best ive seen in the wild so far.
Hi cute ratbird. Can you recommend any good fighters around here?
The weather is pretty bad here, ngl.
Theyre one part master splinter and four parts teenage mutant nina turtle in both looks and skill.
I love cute ratbird 
I came across this bony pachyderm during my searches. It’s got to be good in a fight, right? I mean, there’s nothing left to kill - it’s just bones and tusks.
I played around with ideas for a name - I thought of combinations of bone and mastodon, cartilage and mammoth - but in the end, I couldn’t come up with anything better than “Skelephant”
It’s my best find so far.
Now who would win in a fight? Ratbird or Skelephant… Both Tropical creatures so theyll have similar resistance’s.
That does not sound like a valid combination of words… 
In this case, technically, no. I suppose it;s possible for a very underfed and emaciated elephant to be a bony pachyderm, but it this case, it has no skin.
Still, the term “pachydermata” is (or was) an order of mammals, including elephant - and they remain pachyderms, whether they have skin or not.
In any case, I was just playing with language, looking for a suitable name for the thing. It’s possible to be too picky.
The last update seems to have returned the system instability. My game is crashing every half hour again.
I seem to have hit a bad patch. Arena-worthy creatures have been few and far between.
Here’s the best of a bad bunch:
I have not found anything so far. It seems the highest ranked creatures continue to be the same types of creatures which does not sit well with me. I do not want a companion list filled with the same 4 legged, dog like critters.
If this came out in 2017-2018 era, all the caves would be full of murder crabs and they would all be God Tier ranked.
Is it a thing that the horizontal bars look longer in the scan and shorter in the companion register? As if the maximum was relatively different?
The scan uses some kind of simulated lens distortion - so the picture proportions are far from exact
Arena statistics appear to be calculated at the time of the first scan - i.e. when you discover the creature. When you first scan a creature, the stats bars move up and down, before they finally settle on a fixed value. It would be interesting to see whether another player, discovering the same creature, gets the same stats.
I would assume so. I personally would make the stats a part of the ProcGen, and then just display an animation when the creature is discovered that give the impression of the stats being “assessed” by the scanner. This way of doing it would involve the least amount of tracking, which is usually what you’re looking for in an unbounded system.
They might vary slightly if the one adopted is a different height or weight as this alters the ratio between health and agility. Creatures health goes up as it increases from its base size and its agility decreases. Its agility goes up if its made smaller and health goes down.
Theres always some variance in the creature in front of you and the version kept on record during the scan, i.e if its infant or a gender with stark visual differences than the one it records. So depending on which one you choose to adopt, the stats will probably alter slightly in the health and agility departments.
I must experiment with this and get two companions of the same type but different age and sex
The stats are consistent and follow procgen as mentioned above. They are not affected by the moment of scanning, they just animated the bars to make it seem that way.
I had a link last night to a pet registry. I fell asleep before I could post the link…
