Nothing could stop this Pokémon 100 million years ago, so it behaved like a king.

Tyrantrum is one of the fossil Pokemon of gen 6. It has the unique (to its family) typing of Rock/Dragon. It has the ability Strong Jaw, which boosts the power of biting moves by 50%. It’s based on a T-Rex, though it’s actually pretty small compared to real T-Rexes, being only 2.5m compared to rl ones at 4.6 – 6.1 m. It also weighs only 270.0 kg where T-Rexes can weight 20x that.
Stat-wise, as expected of a T-Rex based Pokemon, it has high Attack (though not as high as Rampardos), good Defense, and ok Speed.
