My personal Top 12 fully evolved Hoenn pokemon:
OK, so I loathe Blaziken with a passion (I know, not many of us around, but I just remember it being a massive disappointment in the actually 3rd Gen Games) and I am pretty indifferent to Swampert, simply because there were so many other water types to choose from in Hoenn.
Sceptile, on the other hand, is a pokemon that won me over almost immediately, and it infuriates me how terribly it gets treated (most of its move set is that of a physical attacker, but its special attack is higher and its mega ability only boosts special attack, its mega form is part Dragon but they only give it Dual Chop by level up rather than Dragon Pulse (hell, Dragonbreath would have been nice!) so a special dragon attack is something you have to jump through hoops to get!)
Swellow always makes its way onto my team somewhere in the Hoenn games and always puts in the work. Gardevoir is always a great catch if you've got the patience to find a Ralts (I am more than a little bit resentful towards Wally for how easily he finds his!) and Manectric is an electric wolf that can also be taught Flamethrower - what's not to love there?
Mightyena is a pokemon that I will always have a soft spot for, no matter how terrible it actually is, Breloom great to have if you don't start with Treecko, Aron can be a b*tch to train but Aggron is worth it, Absol is another pokemon that I love despite it not being too great (and I love the Mega!) Camerupt... is a fire-breathing, sandstorming, earthquake-causing camel - need I explain more?
I must admit that I never really bothered with either Armaldo or Latias until my first play through Alpha Sapphire, but once I did there was no looking back at all!
