Beedrill
Beedrill fly around in swarms of about 5. Upon seeing a player, they will divebomb them, similar to their Pokeball function. After the intial divebomb, they will attack with Fury Attack, which will attack several times in a row, similar to a jab. However, they are very frail, and can be defeated fairly easily.
Parasect
Parasect will often wander around, scattering their Spore wherever they go. If one gets too close, Parasect's Spore will send them to sleep, thus projectiles work wonders. Parasect do not harm the player unless attacked, though their Sleep can cause problems. If attacked, they will attack with a very weak Cut, which does very little damage and no knockback.
Bronzor
Bronzor will float around, and upon seeing the player, will attack with Psywave from a distance. It will charge up, then shoot. This will cause Bronzor significant ending lag. Psywave will do varying damage totals. It can either do very little, about 1%, or very high, about 40%. The higher totals are rarer, but can be devastating if it occurs. Bronzor are immune to ground based attacks, but can typically be dispatched pretty easily.
Audino
Audino can be found passively walking around. Upon seeing the player, they will flee. If one chases them down and defeats them, they will drop massive stat boosts. They are rare to find, and if they run out of view, they despawn. But the rewards one can get make defeating Audino are worth it.
Ferrothorn
Ferrothorn will crawl on ceilings. They will walk side to side on a roof, and won't engage the player. However, upon making any contact with Ferrothorn, the player will take knockback and take minor damage. This can cause disruptions mid battle. They can be defeated from repeated blows, and most easily with projectiles. Fire based moves will deal massive damage to it.
Tyranitar
Tyranitar act as some of the strongest non mid boss enemies around. They can take hits, and dish out massive damage too. They will attack either with Earthquake, which creates a shockwave around it, Crunch, a strong hit for foes right in front of it, or Hyper Beam to deal up to 60% from afar. They are monstrously hard to take down, and thus are rare to find. Upon defeat, they will drop massive stat boosts and rewards.
Voltorb
Voltorb will either use Rollout, during which Voltorb will roll aggressively towards the player, doing little damage, or use Discharge, which will generate an electric shock around it. If at low health, Voltorb will attempt to use Self-Destruct, taking down any enemy within range and doing massive damage to the player. Voltorb can thus be used to the player's advantage if one is skilled enough to utilize it.
Rampardos
Rampardos is a nuke. It's incredibly slow and can be outpaced by nearly everything, and can be taken out fairly easily. However, if allowed to use it's easy to stop and very long Head Smash charge period, it will OHKO any player it touches. It's easy to avoid though, and easy to prevent. Rampardos isn't much of a threat, but it shouldn't be underestimated.
Drifloon
Drifloon will float around, and attempt to grab the player. If the grab is successful, it will attempt to lift them up, but fail due to the fighter's weight compared to it's own. The grab can be buttonmashed out of to get out earlier as well. However, while in Drifloon's grasp, the player will take steady damage over time, and be open to other attacks. Thus, one must always be wary of Drifloon.
Octillery
Octillery will remain stationary. It will attempt to fire Octazooka at the player. It's Octazooka fires very slowly. If hit by Octazooka, it will deal minor damage and cause the player's controls to be flipped. Octillery can be easily defeated by normal attacks.
