From what I understand that guy Brit can shake off damn near anything but can't match someone like Jubilee in power output. Some people punch outside their weight class, some take punches outside their weight class.
Thanos' power output nearly matches his durability—he's far from a butterball-like character. Thanos has inflicted damage on a physically equal clone of himself, Galactus, and other immensely powerful beings. His track record of power output is impressive, and anyone familiar with Thanos' history knows that his power output is on par with his durability.
But my main point concerns the writer's intent. The only reason Odin stated, "I am connected to a SIMILAR reserve," is because the writer wanted us, the readers, to believe that Odin and Thanos are close in power. Otherwise, the writer would be deliberately misleading us.
Here's a summary of the evidence supporting the writer's intent:
1. Thanos effortlessly withstood Odin's blasts at the start of their confrontation. Odin might as well have been shining a flashlight on him for all the good it did. This scene was written to emphasize that Thanos is no pushover and that Odin has some competition.
2. Odin had to brace himself against Thanos' full energy blasts.
3. Odin said, "You tap into a nearly limitless power source, as I am connected to a SIMILAR reserve." This strongly implies Thanos' significant power output, especially since we know Thanos doesn't draw external power to fuel his durability.
4. Odin had to summon Gungnir because his blasts weren't having much, if any, effect on Thanos. He needed to amplify his power to contend with Thanos, underscoring that Thanos is no lightweight and most definitely a peer to him.
5. Thanos fought/waded through Gungnir-amped Odin blasts and still managed to reach Odin and grapple with him over Gungnir. This clearly demonstrates that Thanos is in Odin's vicinity of power.
I'm not claiming that Thanos is equal to Odin in power, but the writer portrayed him to be within 5-10% of Odin's power. My argument focuses solely on that particular writer's intent. We can argue that Odin is significantly more powerful than Thanos based on their overall comic history of feats. We could even argue that this was a low showing for Odin or PIS. That would be more logical than the absurd "Thanos is a butterball-like character" theory.
