Tyrantrum

Tyrantrum's most defining trait is its access to Rock Head and STAB Head Smash, giving it an absurdly powerful attack with no immediate drawbacks that dents any Pokemon that does not resist it and lets it act as a powerful holepuncher or cleaner. Rock is a powerful offensive typing, granting Tyrantrum good coverage against a majority of the tier and making Head Smash quite spammable. Tyrantrum has good neutral coverage and a considerably wide movepool, although all it really needs are moves that take on the few Pokemon in the tier that can consistently withstand its Head Smashes. These qualities present Tyrantrum as one of the tier's most potent attackers and holepunchers. However, Tyrantrum's Speed is noticeably lacking as a Choice Scarf user, failing to outspeed Pokemon such as Choice Scarf Gardevoir and Mega Sceptile. Tyrantrum's low Special Defense combined with its awkward defensive typing and multitude of weaknesses often turns it into a defensive liability, making Tyrantrum function as a glass cannon. Tyrantrum is thus heavily reliant on its few physical resistances and 4x resistance to Fire to avoid getting 2HKOed by invested attacks.
