Spidey can't handle power cosmic amp2

Spider-Man having a power cosmic/"power cosmic equivalent power" amp (which makes him a thousand times stronger) is something his body cannot handle for too long without exploding. He thinks Galactus is someone he could burn all of his energy off on by attacking. Spider-Man agrees that he is a pathetic parasite compared to Terrax and not a top tier hero without this amp. Iron Man in a narratively outdated armor used due to newer ones being unavailable, proceeds to no-sell a direct slash from Terrax after Terrax one shots Odinforce/immortal Thor with a blast. Storm & Captain Marvel on the other hand personally feel they cannot beat Terrax without help from Thor -Astonishing Spider-Man Infinity Comic (2024) issue #33

Ironically Iron Man in the same exact armor while weakened & low on power, absorbed a blast from a Terrax trying to kill him and channels all the energy back through his repulsors to put down Terrax with a single attack: https://zippyimage.com/album/silver-centurion-vs-terrax.i02JK

Iron Man in extremis armor, physically overpowered Terrax casually & presumably disarmed him off-panel. The moment Tony stops talking to his armor & gets serious, he sends Terrax flying out the solar system at faster lightspeeds with a single hard shove that makes Terrax' s body propel that far in less than a night's worth of time: https://zippyimage.com/album/extremis-iron-man-2020-vs-terrax.i9Qgj

In Marvel's Voices: The Avengers
Iron Man cites that he has faced off against Galactus off-screen and came out with a victory https://zippyimage.com/album/iron-man-vs-galactus.idhl7

Silver Centurion had used its hands to mold celestial metal & made a lid that successfully held Tiamut the Dreaming Celestial's essence: https://zippyimage.com/image/iHIWH8

Basic Iron Man & Rescue armors have been listed on the same threat level as Sols Anvil, which was shown to be much more powerful than the Mad Celestials & a peak power Galactus under the same writer: https://zippyimage.com/image/iuEv5K

Iron Man at below base power levels is above the power cosmic: https://zippyimage.com/album/iron-manpower-cosmicimmortal-hulk.xOHnu

When Iron Man was imbued with the power cosmic, he was far above God Korvac, Living Tribunal, In-Betweener, Molecule Man, and the Progenitor Celestial (a Celestial that Odinforce Thor and the Phoenix force together were stomped by etc.): https://zippyimage.com/album/respect-iron-god.x8i70
