Can Mega Lopunny be used Competitively?

Yes you can. There are many ways to use it. Do you want me to show you a set here?

 

Mega Lopunny is completely viable competitively. It is one of the more versatile Mega Evolutions out there actually, as there are quite a few sets for this thing. It also helps to have a Pokémon with stat raising moves and Baton Pass, so that you can cover up some of Mega Lopunny's weak points.

 

Mega loppuny tho viable it is like a copy of mega beedrill it can hit but cant take hits its set would ogo like

Loppuny-mega@Loppunyite(or err the stone name hting)
Abilitycrappy
EV's:252Spe/252ATK/4(umm anything)
-fakeout(to cover a bit of damage)
-Highjump kick
-Ice punch
-(tho this is kinda optional) you can use here any move you want as long as its strtegy like make it healbell for example its a quick heal if your tanks/walls are faceing a sweeper like i dunno kyreumblack or thunder wave or a stat boosting move which loppuny can use or encore if thers a setup sweeper you wana stop before its too late we have magic coart for those who try to burn loppuny very effective vs sabeye since it will just will-o-wisp you at the fist turn and loppuny tho having scrappy might miss highjumpkick or just plain on not kill it

 

[member='MajesticFlygon'] You can take Wiso Altred Example Or if you want other optins I can post them

 

Most lopunnies in the competitive tiers are jolly and they tend to run fake out + fighting STAB (I prefer low kick or Drain Punch because High Jump Kick's inaccuracy can basically nuke itself), a normal STAB (Frustration or Return), and either a setup move or a coverage move.
The EV spread tends to be max atk and speed, plus 4def.

Picture a faster drunk Easter Bunny, AKA Diggersby, without four moveslot syndrome.

 

Ading return is a good idea i forgot about that drain punch can be more usefull if you needed a tank tho

 

Drain Punch can be a really good option if you're running substitute, while low kick would be for Tyranitar or Terrakion, provided they are not choice scarfed.
Lopunny doesn't have that good of bulk so it cannot really tank.
If I recall correctly, with max speed EVs and jolly, lopunny can outspeed +1 base 81s with a neutral speed nature? Which means adamant dragon dancing Moxie Gyarados can get ohko'd by a thunderpunch by the flipping poke, as an example.

Could someone confirm what + and neutral speed tiers a base 135 speed jolly mega lopunny prioritizes with +0 priority please?

 

Mega Lopunny is a great 'mon to throw out late in the game. If you're doing doubles, I'd recommend you have a support team mate on hand to help buffer some hits. It can take a licking, that much is true, but the longer it stays alive, the better. Scrappy is also an amazing ability, allowing you to Hi-Jump Kick ghost-walls (especially Mega Sableye). Mega Lopunny can also learn healing wish, so I would recommend you at least contemplate slipping that move into its moveset. Honestly, I had great fun using this Mega.

 

My friend is training a Mega Lopunny. Show me what you think.

lol I think it's Fake Out/Hi Jump Kick/Return/coverage. you can use Toxic for Slowbro and crap, or Ice Punch if you're worried about Dragons. You can even use Healing Wish if you're that kind of person.

Fake Out is only to guarentee the MEvo and get the Speed boost.

 

I run this Lopunny on my Normal monotype team, I find it useful to battle ice type teams using high jump kick. you could substitute cute charm for another ability as I don't find it that useful.
