I'mma just stop replying to you after this comment since i am tired of dealing with your bs every day of my already hard life.
Horrible comparisons? Anti-feats? You are trying to upgrade Heatran of a vague-ass feat that doesn't support shit. He has no 2-A feats, he's never hurt a single member of the lake trio and at best he slightly released the abilities of the plate.
Headcannon? Shut tf up, at this point it's pot calling the kettle back. You just proposed to nerf the lake trio to high 7-A based on a weird interaction from an anime filled with weird internactions. The lake trio broke the red chain and stopped dialga and palkia in the games, they also were able to parry attacks for the CT in the manga. If that ain't dumber than what i proposed then idk what is.
Also how is it headcanon? Headcanon is when i say something that i assumed is canon when in reality it isn't. What i said was what was shown. Lake trio never got properly harmed by Heatran, Heatran never absorbed the plate but just made it go berserk by pouring energy into it.
They literally used a stress machine to make the plate work and then used a massive energy attack from Heatran to make it release even more energy. He never absorbed it, in fact, Heatran was the one absorbed by the lava form which appeared due to the fact that some energy traveled back at heatran and made his abilities go berserk. Unless you can provide evidence that he used the full power of the plate and not just used it as a battery then you ain't gonna upgrade anything.
Also i think the fact that the explosion that would kill heatran would only destroy Sinnoh and not, you know, the universe, is enough proof that he doesn't constantly use 2-A levels of energy. Just because an electric hairdryer has a nuclear reactor powering it up doesn't mean the hairdryer is 7-C does it? Neither does being slightly powered up by a plate mean that you're using full 2-A energy.
