This page explains how to defeat Elite Four Aaron.
Aaron is the first member of Sinnoh’s Elite Four, specializing in Bug-types. You could be scared of bugs, but you might not consider them fearsome opponents. Well, time to re-evaluate that line of thought!
Elite Four Aaron
To begin with, Aaron sends out Dustox, which evolves from Cascoon. It can use Light Screen to weaken your special moves, Toxic to cause deadly poison, Moonlight to restore HP and Bug Buzz for damage. It’s holding a Black Sludge, which slowly restores HP. It may use Toxic and then try to stall you out with Moonlight and its Black Sludge. End it quick with Fire, Flying or Rock-types.
Aaron also has a Beautifly, which evolves from Silcoon instead. This one can use Quiver Dance to greatly boost its Special Attack and Speed, then hit you with STAB Bug Buzz. Or Psychic/Shadow Ball. Do not give Beautifly the chance to use Quiver Dance; target it with Fire, Electric, Ice, Flying or Rock-types. Bonus points for Rock.
Vespiquen is an evolved female Combee. It can use Attack Order and Defend Order to boost its stats. Otherwise, it can attack with Aerial Ace or, after consuming its Sitrus Berry, Acrobatics. Compared to Beautifly, it’s much less of a threat. Smack it with the same type(s) used for Beautifly.
Heracross is a threat right off the bat, with great offensive stats and hard-hitting moves. Earthquake is a good all-rounder, while Rock Slide can cause annoying flinching if Heracross is faster. There’s also Brick Break to smash Reflect/Light Screen and Facade to deal major damage if suffering an ailment–dangerous combined with its Guts ability. Nothing is safe, but a fast Psychic or Fairy-type would be great here.
Finally, Aaron’s ace is Drapion, an evolved Skorupi. This one isn’t a bug, so keep that in mind. Its attacks include STAB Cross Poison and Night Slash, which have boosted critical thanks to its Scope Lens– and will hurt more due to its Sniper ability. It’s also carrying Earthquake and X-Scissor for coverage. Drapion’s only weakness is Ground. Regardless, avoid Psychic-types.
