Location: Pallet Town

Details:
The first fight takes place right after being robbed of your starter. Your rival will steal Eevee while Oak gives you Pikachu; however, since the only attacks either of you have at the beginning belong to the Normal-type, you have nothing to fear, except the same type attack boost Eevee gets. It should be an easy first match as long as he doesn't score a critical hit.

Left of Viridian City your rival will be training his starter and newly caught Spearow; this remains applicable until you pick up your first badge. Though the first should be easy enough with your starter, you may want to grab a Mankey in the nearby grass if Eevee gives you trouble.

Details:
On the way to the Sea Cottage on Route 25, your Rival will be waiting on Nugget Bridge for your challenge. Rather than helping Bill change back from being a Pokemon, your rival decides hanging out on the bridge is better use of his time. His team has expanded to include a Rattata and Sandshrew. As his starter will still be in its basic stage the most you'll have to worry about is Sandshrew's Sand Attack blinding your Pokemon and Rattata's Hyper Fang inflicting massive damage. Eevee is still pretty weak so deal with it with something weaker that you need to train.

Details:
Kind of like the last time you fought him, only things are at a higher level. Sandshrew has Slash now, which has a higher critical hit ratio. This fight shouldn't be any harder than the last one because it's pretty much the same team.

Details:
This is where rival's team really takes shape. By now his Ratatta has left the party (strange considering he speaks of dying Pokemon and is hanging around infront of a grave...) and been replaced with the second and third of the elemental trio he'll have in coming battles. Your team should be reasonably balanced and ready to handle the newly evolved Fearow like last time as well as his two newcomers. Fortunately his movepools leave much to be desired still so use that to your advantage. If your rival is using a Shellder avoid using physical attacks as they'll do nothing with the Pokemon's obscene Defense.

Details:
By now the rival has given his Pokemon some decent moves and gotten his old Pokemon to their final forms. Kadabra replaces Fearow now. Though still not terrific by any stretch of the imagination, various moves might be a problem if they catch you off guard so beware. A good idea is to have an Electric-type on your tea; the majority of his team will fall to a fast Thunderbolt. Get rid of Kadabra as soon as possible: Psybeam can wreck your team with its speed and precision or confuse you if you stay alive.

Details:
This match might be a little nostalgic if you didn't pass up on his second challenge earlier in the game. By now you should know what you're doing; whatever it is, keep doing that! Kadabra has a frighteningly strong Psychic attack and Sandslash never misses when Swift is used. Exeggcute has the annoying Poisonpowder/Leech Seed combo. If he uses a Jolteon watch out for Agility - it will ensure this thing is the fastest Pokemon in battle. Flareon gets Flamethrower which has very high base damage and can burn. Vaporeon will Acid Armor to make it impervious to physical attacks. This team is a good warm up for the Elite Four...and the champion after that.

Elite Four: Rival
Specialty: None

Details:
The circle is now complete. Your first and last challenge is with your rival, and he'll have just as many tricks as ever to face you. With a fully rounded out team you'll be hard pressed to find one Pokemon to take everything out. Balance everything out as always: don't train just one Pokemon (seriously don't) and make sure your type coverage is astute. Ninetales and Cloyster will try to trap you with Fire Spin and Clamp respectively, Sandlash hurts Grass-types with Poison Sting and Earthquakes anything that it doesn't miss, Exeggutor only has one damaging attack (the Normal-type Barrage), and Alakazam has fearsome Psychic power. Pay extra attention to his starter, who always has dual coverage (Poison/Fire for Flareon, Bug/Electric for Jolteon, and Water/Ice for Vaporeon) and an extremely strong STAB move. One approach to this is to just use Toxic on everything (use PP Up if you're doing this) and stall it out with Chansey or another bulky Pokemon. It's not exactly enthralling but if it's what works go for it. Good luck!
