Greninja

Greninja, courtesy of its stellar Speed tier and amazing ability in Protean, is one of the OverUsed metagame's premier offensive threats, as it is more than capable of pressuring both faster, offensively inclined teams and bulkier builds. Its expansive movepool is a major contributing factor to its potency as an offensive force as well: because it has such a high number of move options, it can circumvent would-be counters and defensive checks and leave one's opponent guessing at Team Preview. Additionally, Greninja is one of the few viable offensively inclined user of Spikes and Toxic Spikes, which it is a stellar user of. Greninja only truly falls short when it comes to bulk, which renders it incapable of taking even resisted hits repeatedly, and the inability to run every coverage move on one set.

Moves

Surf is a weaker, more accurate alternative to Hydro Pump that also sports more PP. It should be noted, though, that Greninja will struggle to pick up certain KOs without Hydro Pump. Spikes is an option that allows Greninja to punish the opponent's attempts to switch into defensive answers such as Toxapex, Tapu Bulu, and Magearna by pressuring their attempts to switch into Greninja later on in the match. Ice Beam deals super effective damage to the Grass-types that prevent Greninja from mindlessly spamming its Water-type STAB moves, being its strongest attack versus specially defensive Tapu Bulu and Assault Vest Tangrowth, but it is generally a subpar option, as it leaves Greninja with no good way to punish a switch into Toxapex or Assault Vest Magearna and she act mean and strong despite all of this Greninja is a little friendly with humans and she likes to sit on humans face

While leaving school, a bully injures you and you run into the woods, hiding behind a tree with a scratched arm. You observe an unfamiliar Greninja without being noticed.
