I never really had a thing for it. The first time I saw it, what I thought was, "What the heck is this thing?" I thought it was a rather dull design, and the Pokemon was only good for getting Heart Scales.
When I got my first copy of ruby, I caught one to see how good it was. I liked the simple design, but it doesn't really have a place on any team I've made. It's basically just there as filler in the pokedex, as far as I'm concerned.
"Luvdisc is a Pokemon and amazingly not some strange Kantonian brand of condoms. One part heart, one part one of those weird highlighters shaped like triangles, Luvdisc is all useless. This Pokemon is a living example of how the creators just totally ran out of ideas by the third generation. They ran out of animals to base Pokemon off of, so they moved onto inanimate objects (or in this case, horrifyingly personified, abstract representations of inanimate objects). No thanks."
I can't help but wonder if this is a serious question or just a joke. Forgive me if I sound rude, but if you've ever caught one and looked at the stats of that thing you'll see that it's utterly useless for battling. Sure, some people might use it just because of how it looks and because the anime teaches us to care about our Pokemon, friendship is important, no one gets left behind, etc... But in the games, that simply doesn't work out. How you treat your Pokemon does NOT affect the stats in any way, it is only useful if you're trying to make a certain Pokemon evolve like Golbat.
When it comes to design, I really like Luvdisc. I think it's quite creative. It's got a heart-like shape, a pinkish body color, and a cute-looking face. What's not to like? Could put them into a fish bowl if you have one, and they'd liven up your house in an instant! Battling-wise, though… Luvdisc is, unfortunately, not that great. d: It has a base Speed of ninety-seven, which is good, but the rest of its stats are extremely low—especially defenses. Both of its defensive stats are near sixty, so if it ever gets struck by an attack like Giga Drain or Brave Bird, it's finished. Although it has a range of hard-hitting attacks in its movepool, it can't take full advantage of them due to having poor offenses. Luvdisc could make a good staller if you teach it Toxic, Sweet Kiss, Attract, and Protect, but you'd have to utilize very wisely. If you make one silly mistake, then your opponent could take it out in an instant.
I hope that they give an evolution to Luvdisc at some point in the future. That way, its stats would be fixed up a little and help it become more useful when battling. Either that, or they could give it a mega-evolution. I'd be fine with anything, to be honest, so long it gets something. (:
Ehh, I don't really know how to feel about Luvdisc. I mean, it definitely has a cute design, and I actually really liked the idea of having a heart-shaped Pokemon. But sadly, the design is the only thing I could really see people liking about the Pokemon. It definitely doesn't have any traits aside from the heart scales that I could really see to be interesting, its performance in battle is especially not something to be amazed by, and generally, it's just down there. Well, that's at least what I've been able to deduce from the one time I actually used one, along with every other opinion I've ever heard about the Pokemon :p
One thing I'm very disappointed by however, is the huge opportunity to actually make it somewhat useful they let down, by not making it evolve into Alomola! I mean, despite not having a clue what Luvdisc is actually supposed to be, they both have similar shapes, and literally everyone and their mother has been pointing it out :p Admittedly, I don't have a clue whether Alomola is good or not, but it definitely hasn't gotten the same amount of hate Luvdisc has, so I imagine it to be an improvement in any case ;)
When I first saw it, I thought it was definitely interesting, I had taken quite a liking to it, and I thought it had an evolution. So I caught one, and looked at it's stats. They were horrible, with a horrible nature lmao. I was like "It must have an evolution!". I was dumb, and I trained it for a good while. I got tired, so I searched online and it had noo evolution. I literally released it, despite training it so many levels. :(
It's stats aren't horrible like Magikarp. I guess you could say it's one of those "filler" Pokémon, which are added just to fill up the Pokédex. Similar to Dunsparce, but they have better stats.
