A Charizard's flames are hot enough to melt boulders (21,000 degrees fahrenheit).
Learned Seismic Toss, which involves the user THROWING IT'S OPPONENT INTO NEAR-ORBIT (considering an average weight of 200 kg for any given Pokemon, and the speed of 11,814 km / mach 6,888.62, in which they travel when thrown in 5 seconds, that's over 133.43 kilotons of TNT / 133,430 tons of TNT).
