That's always a gag scene though, in the manga and anime.
True enough to be fair, but the other point would be every single Pokémon that Charizard attacks with a Flamethrower that - apparently - has the power to break a boulder and melt almost anything.
Some more Pokédex madness includes:
Blastoise's water cannons can fire so strongly they can even punch through thick steel.
Pidgeot can see a splashing Magikarp...3300 foot up in the air...and can fly at Mach 2
Raticate in one entry boasts being able to topple concrete buildings...by gnawing them
Nidoking in one entry boasts a horn so hard that it can pierce diamond
Ninetails can live for 1,000 years in Pokémon Silver's Pokédex entry
Machoke from varying entries would be unstoppable if you remove it's special belt and in another version it
never gets tired. Then there's
Machamp who can move mountains with one arm and can react faster than it can think.
Rapidash can reach it's top speed of 150mph after just ten steps...yeah
Professor Oak is touched by
Muk all the time in Anime, but by Pokédex just touching Muk results in a high fever that requires bed rest.
Cloyster has a harder-than-diamond shell and even missiles cannot break the spikes it fires from it...which are even harder. Oh and once it closes its shell it's impossible to open. By anyone. Even if they're stronger.
3,600 degree magma is of no consequence to
Rhydon.
Gyarados can destroy entire cities in a rage - that's one, single Gyarados where the Anime would require it to be a gang of them.
