Tangrowth

As a physically defensive Pokemon, Tangrowth faces stiff competition from a variety of Pokemon in UU, including Slowbro and Shaymin. At the same time, it is fairly unique in what it does; with good offensive stats, impressive physical bulk surpassed only by some Rock- and Steel-types and Cresselia, and the great support moves that Grass-types tend to have, Tangrowth is blessed with enough versatility to function as a hard-hitting wall or a bulky sweeper. Defensively, its typing is a double-edged sword, having five weaknesses, but also key resistances to Water and Ground. In addition to this, Tangrowth has plenty of ways to recover HP, including Regenerator, Leech Seed, Giga Drain, and Synthesis, allowing it to continue to frustrate physical attackers throughout the fight. However, these advantages are counterbalanced rather cruelly by its cripplingly low Special Defense and Speed stats, and the fact that Regenerator Tangrowth cannot learn Synthesis. Like a good rope, Tangrowth may not ward off fires very well, but one can depend on it to hold in the face of physical brutality, and to dish some back out.
