trinity superman's best feats were defeating his anti matter counterpart easily, defeating a partially cosmic egg amped dark trinity (who are planet level threats), and his best feat is holding his own against krona and eventually overpowering him with the help from cosmic batman and wonder woman and the world soul.
Defeating krona was PIS imo, it was entirely inconsistent with how they were depicted throughout the volume 3 of the series.
all of the feats i listed were done by the cosmic superman, but throughout the volume he didn't show any abilities beyond planet level. while krona on the other hand, was bigger that an entire universe at on point, and released a galaxy busting attack just prior to his defeat at the hand of the cosmic trinity.
in the first one, kellek managed to hold his own against krona for a little while and batman came up with a plan to trap krona, but then krona escaped from the trap (with the help of morgaine le fey who was empowered by krona) and then the cosmic trinity (superman, batman and WW) with the help of the world soul managed to defeat him.
And the ridiculous part is that they didn't just face off against the universal krona (past krona) but the yellow version of him who, as you can see in the scan, oneshotted his past self (a universal embodiment), id say that's above universal for sure.
However, i consider this PIS at its highest, they didn't show power even remotely close to put them on par with krona.
Well, just because they didn't show anything like that before doesn't mean it's PIS. Did Kellel struggle with anything below that? Like a weak villain?
no, that's actually a point to argue about, everything they did, they did it casually, they didn't seem to put effort in what they're doing until they faced krona.
However they took quite some time repairing a continent, if they were of krona's caliber, they would do it with a thought.
I think what opertaot616 is saying that, Trinity Superman, Batman and Wonder Woman didn't show on a consistent level of power to battle Krona let alone defeating Krona who dismissed his older self Entropy with a gesture, something is wrong with that.
That would be like RKT defeating the Infinities and never showing the power output to even register a threat level on their radar. RKT should us he defeated a console of Celestial beings with ease, defeating Mangog with a gesture something Odin couldn't have done, defeating a sky father level being in Loki who absorbed all the power of Asgard and beat him like he wasn't even sh**, and put the fear of God in Surutr.
RKT proved his status as being above Odin 2X over, as where the Trinity didn't.
Was it mentioned that their primary abilities were reality warping? How did Kellel fight Krona? With pure power like strength? If so, I can see Kellel taking it to RKT with similar results.
their weren't any specifics to their abilities, they recieved partial powers from the cosmic egg.
Galan007 posted a few scans in krona vs impreiex thread, though he left out a few scans in their battle against krona.
if you want i'll post their second fight, but i can't do it today, i'll probably post it tomorrow.
