Like they did with underwear, and then formal evening wear, Overwatch cosplayers have once again taken their favourite characters and put a little spin on their outfits. This time, the theme is punk.

Last year's BlizzCon was one of the higlights of the cosplay calendar. BlizzCon 2017 was no different.

Over the years, Hearthstone updates and expansions have added a heap of new cards, modes and strategic possibilities. However, one thing has remained unchanged since the digital card game's release back in 2014: Character classes. There are only nine, and despite some clamour for more, that number is unlikely to change any time soon.

"I think on the big spectrum of loot boxes, between 'really good' and 'really evil,' I'd like to think we're more on that 'really good' side with what we're trying to do," says Overwatch game director Jeff Kaplan.

It's said that a new Overwatch fan fiction springs into existence once every 26 seconds. Most of them, unsurprisingly, are about ships such as Pharah-Mercy (good) and Genji-Mercy (a travesty). Naturally, Overwatch director Jeff Kaplan has opinions about it.

The years have not been kind to fans of Warcraft's real-time strategy roots. Before each BlizzCon, a dwindling contingent of hopeful fans prays for Warcraft IV to no avail. But WoW's next expansion Battle for Azeroth might contain the next best thing.

These days, it's hard to talk about Overwatch without mentioning its ongoing struggles with sexism, racism, griefing, match throwing and worse. At BlizzCon, game director Jeff Kaplan told Kotaku that fighting toxicity is now more of a priority than ever, to the point that Blizzard has formed a "strike team" to do so.

Any Overwatch players who are fans of a Mercy x Genji romance, here's some BlizzCon cosplay to warm the heart.

Two new heroes will join the Heroes of the Storm roster: Alexstrasza from World of Warcraft and Hanzo from Overwatch. They're coming to Heroes of the Storm in the coming weeks, and both characters made their debut on the show floor at Blizzcon 2017.

With its colourful cast and proclivity for wild plays that are equal parts tactical and mechanical, Overwatch is brimming with esports potential. Problem is, it can be a mess of exploding mechs, screen-engulfing ghost dragons, and middle-aged men in Scream Halloween costumes -- too much of a mess, sometimes, to actually sit down and watch.

The 2017 Overwatch World Cup finals saw reigning champions South Korea take on Canada, the mighty titan versus the underdog. There were cheers, excitement, and one very polite signholder in the crowd.

Blizzard has revealed some new cards from the upcoming Kobolds and Catacombs expansion at BlizzCon, and they're already looking pretty silly.

Gray walls, nothing but Tracer, and bullet paths that looked like yellow lasers. In late 2013, this was what Overwatch looked like.

On the BlizzCon show floor this weekend was a massive World of Warcraft diorama. There are 10,000 characters in it, but here's the crazy part: each figure is based on an individual BlizzCon attendee's actual in-game character. It's totally wild.

Here is concept art of legendary scrapped Overwatch hero, Jetpack Cat. During a BlizzCon panel about Overwatch's formative days, game director Jeff Kaplan and art director Arnold Tsang talked more about his origins, saying that they were trying to figure out how far was too far with regards to character designs.

In some ways, Overwatch's new hero, Moira, announced yesterday at BlizzCon, feels like a stronger take on the basic premise underlying sniper grandma Ana: she's a healer for people who hate playing healers.

Like they did with Doomfist, Blizzard used the announcement of a new Overwatch hero today to indulge in a little company-sponsored cosplay.

If you try to level a new WoW character, you're basically asking for mad deja vu. Ahead of the release of a new expansion, Blizzard is gonna let players change things up. A lot.

During today's Blizzcon 2017 keynote, Blizzard announced Battle for Azeroth, the seventh expansion pack for World of Warcraft, rekindling the war between the Alliance and Horde.
