Garchomp

The most formidible dragon ground type known in pokemon history and often as a tyranitar equal or slayer due to its sand veil ability and highly valued by top trainers due to its almost criminal high stats and out manuvers its predececors tyranitar and dragonite easily and puts up a good fight against salamence and metagross, like flygon it is vulnerable to ice type attacks if tought flame thrower or fire blast it will protect from that weakness although not effective against water/dragon types(Kingdra and palkia), and it's the forth most powerful non legendary along with its predecesors. Trivia: It has the same star shape on its head as sharpedo. Although it cant really fly like the dex entry said, but it can swim like most monster egg group class pokemon and a second compatible breeding partner of charizard and sceptile(all three monster/dragon egg group).
