Template 1: Power level explanation at 6%

Physical Strength

- Lifting Strength: David could lift around 600 tons, approximately six times stronger than at 1%. This surpasses the base forms of the Hulk and Thing by a large margin and approaches heavy-hitters like Thor or in rage Hulk.

He could lift and throw large objects like ships, small buildings, or massive tanks.

Speed

- Flight: David's flight speed would be around Mach 6-12(4,500-9,000 mph), allowing him to travel much faster and cover countries in minutes. He wouldn't yet reach Superman's top speeds but would still be much faster than most heroes on Earth. 

- Reflexes/Combat Speed: David could easily dodge bullets, missiles, and energy blasts from close range.

His speed in combat would enable him to keep up with high-speed opponents, allowing him to contend with characters like Iron Man, Thor, or even Quicksilver (though not at his highest speed). 

Opponents like Makari at her highest speeds can move at light speed at risk of displacing herself would leave David helpless.

Durability

- Invulnerability: David would now be able to withstand most conventional and heavy firepower, including powerful energy blasts and attacks from enhanced foes like Iron Man or Thor.

However, very high-powered attacks from characters like the Hulk (in rage) or Black Bolt could still harm him.

- Healing Factor: David's healing would be notably faster, allowing him to recover from serious injuries within hours rather than days. His resilience would still not be as fast as Post crisis Superman's at full power but would be effective in long fights.

Heat Vision

- Potency: His heat vision could melt through most materials, including steel and dense metals, and damage extremely tough materials, though it still wouldn't reach the capacity to destroy adamantium or vibranium.

He could unleash a blast to take down larger structures or even smaller fortifications.

Enhanced Senses

- X-Ray Vision: His x-ray vision would continue to allow him to see through obstacles within a larger range, making him very hard to ambush.

- Hearing: David's super hearing could detect sounds from up to 100km away, allowing him to monitor wide areas for threats.

Combat Capabilities at 6% Power:

At this level, David would be a major force on the battlefield:

- Who He Could Defeat: David could comfortably defeat most mid-tier heroes, including Iron Man (in standard armor), Captain Marvel (lower levels), and others like Black Panther or Wolverine.

He could handle teams of lower-tier heroes simultaneously, such as the Defenders, and would outmatch enhanced characters like the Thing, Venom, or Colossus.

- Who Would Challenge Him: Stronger heroes like Thor, World War Hulk, or Captain Marvel (at full power) would present a though challenge, as their power and durability are closer to his new level.

Characters like Black Bolt or a high-speed Quicksilver could also push him to his limits, especially if they exploit weaknesses.

There are still several charecters that outmatch David but I unfortunetly don't have the patience to sit them all out, sorry :)

Overall, David's 6% power makes him a dominant force, able to rival some of Marvel's most formidable non-cosmic heroes but still below cosmic-level or magical threats.
