So you've caught a Whismur early on in Hoenn, raised it into a Loudred, then leveled it up all the way to 40 (which is a few levels after your starter has reached its final form, by the way)... Congratulations! Your Loudred has evolved into an Exploud. That thing sure looks threatening, so how threatening is it exactly?
Its Attack and Special Attack are both 91. Its highest stat is its 104 HP, and the rest of its stats are pretty mediocre. Sure, 91 in both attacking stats isn't awful, but I'm pretty sure most people would have expected a better Special Attack from this thing, and freakin' Seviper has higher Attack AND Special Attack than it. You could argue this is because of the lack of a physical-special split, and the fact that Exploud does look like it can physically dish out some serious hurt (especially with its giant mouth), but I don't know. For something that you get at Level 40, you'd think this thing would pack a bigger punch.
To add insult to injury, Generation VI was kind enough to bestow stat boosts onto some Pokémon, and Exploud was one of the lucky few to receive one. What did it get? A buff to one of its attacking stats, preferably Special Attack, since it can now make use of Boomburst alongside its Scrappy ability? No. +10 to Special Defense, making it a slightly less awful 73. Strange.
