After undergoing Mega Evolution, Mega Swampert takes on a much different appearance. It appears to be bipedal with a significant increase in muscle mass throughout, most notably in its arms and torso. Its head fins are stream-lined and there are now three instead of two. Mega Swampert's face whiskers extend outward from its cheeks, forming three sets of horn-like spikes on the sides and a fourth set of smaller, horn-like spikes facing down.
Mega Swampert doesn't appear to have any visible differences to differentiate between male and female.
A Mega Swampert can be obtained in battle by having a Swampert hold a Swampertite, then using the Mega Stone to have it Mega Evolve into Mega Swampert, however this will only work in Omega Ruby and Alpha Sapphire.

Mega Swampert is in the Underused (UU) tier of competitive battling where it is among the best Pokémon in the tier. With a high 150 base Attack and access to Swift Swim, Mega Swampert is an ideal Rain Dance sweeper that can prove to be dangerous with strong wallbreaking capabilities and sweeping power with doubled Speed. Mega Swampert's balanced 100/110/110 defenses allow for many opportunities to set-up, while its rain-boosted Waterfalls and solid overall coverage with Earthquake and Ice Punch allow for it to be effective after getting rid of physical walls. Due to its overall good defenses, Mega Swampert is a candidate for an offensive Stealth Rock setter which has good tanking prowess while being able to dish out some strong hits of its own. While a physically defensive set faces competition from base form Swampert, Mega Swampert can use its higher defenses to check certain threats that base form Swampert cannot do as reliably, such as Choice Band Krookodile. Mega Swampert can also use a Curse set that makes it hard to take down due to heavy Special Defense investment and accumulated Defense boosts. The flaws with Mega Swampert are that it lacks any form of reliable recovery, having to rely on the Rest and Sleep Talk combination, and that it has a crippling weakness to Grass-type attacks.
Mega Swampert is also a viable option in the Overused (OU) tier of competitive battling. Thanks to its immunity to Thunder Wave, Mega Swampert can find a great niche on rain teams as a Pokémon that is not instantly crippled by rain nuisances like Thundurus and Klefki. Mega Swampert is a very powerful Pokémon under rain with a great Speed thanks to Swift Swim, strong rain-boosted Waterfalls, and good overall coverage. However, Mega Swampert does not get a Swift Swim boost on the turn it Mega Evolves, so it is slow for a turn. Its speed also does not allow for it to outspeed some Choice Scarf users like Keldeo even when under rain.
