If you’ve hopped into Dota 2 for the first time in 2026, or you’re a long-time fan arguing with friends over the game’s early days, you’ve probably asked how many heroes did dota 2 have on release at least once. It’s a surprisingly common question, partly because the hero pool has ballooned so much over the years that even OG players often mix up the original 2013 launch lineup with later additions. We’re breaking down the exact number, the most memorable original heroes, how the pool has changed up to 2026, and why that small initial lineup laid the groundwork for the MOBA we know today.
The Exact Answer to How Many Heroes Did Dota 2 Have on Release
The official number of heroes available when Dota 2 launched out of beta in July 2013 is 102. That’s a far cry from the 135+ heroes you can pick from in 2026, but it was already a bigger lineup than most competing MOBAs offered at their own launches. A lot of players misremember this number as 90 or 110, because the beta period in the years leading up to launch added new heroes every few months, so people who joined during different beta phases have different memories of what was available. Only heroes that were fully playable and balanced for the full public launch count towards this official number, so beta-exclusive test heroes don’t make the cut.
Of those 102 original heroes, three stood out as the most picked in the first 3 months of launch, according to old Valve player data:
It’s fun to note that all three of these heroes still rank in the top 15 pick rates in 2026, so their appeal hasn’t faded even after 13 years of new additions and meta shifts. You can still find one of them in almost every casual unranked match you play, no matter what region you queue in.
Why the Original Hero Lineup Was So Important for Dota 2’s Long-Term Success
A lot of modern players assume that more heroes always equal a better game, but Valve’s choice to launch with 102 carefully balanced heroes was intentional, and it’s one of the reasons the game still has such a dedicated fanbase in 2026. Every original hero was ported directly from the original Defense of the Ancients mod for Warcraft 3, so existing fans of the mod could jump straight into Dota 2 without having to learn a new roster of characters. That seamless transition is what built the initial core player base that kept the game growing through its early years, even when competing MOBAs were spending millions on marketing to poach players.
Valve also made sure that the original lineup covered every possible play style, so no matter what type of game you preferred, you had a hero that fit. If you liked playing aggressively and getting kills early, you had gankers like Nyx Assassin and Clockwerk that could shut down enemy carries before they got their core items. If you preferred supporting your team from the backline, you had dedicated healers and ward spammers like Crystal Maiden and Treant Protector that could turn teamfights around without dealing huge damage. If you liked carrying your team to victory late game, you had hyper carries like Phantom Lancer and Anti-Mage that could wipe entire enemy teams on their own once they were farmed. There were no gaps in play style options, even with the smaller pool compared to 2026’s roster.
How the Dota 2 Hero Pool Has Grown From Launch to 2026
Between 2013 and 2026, Valve has added just over 30 new heroes to the game, bringing the total hero count to 135 as of the 2026 Spring Patch. New heroes are usually added once or twice a year, with full reworks of older original heroes happening every few patches to keep the meta fresh. Unlike many other MOBAs that add overpowered new heroes to drive sales of cosmetics, Valve has always prioritized balance for new additions, so even the newest heroes don’t feel unbeatable if you know how to counter them. Some of the most popular new heroes added post-launch include Mars, Void Spirit, and the 2025 addition, the fey support hero Lirael, who already has a 22% pick rate in support roles as of 2026.
If you’re a new player joining in 2026, don’t feel overwhelmed by the 135 hero count. You only need to learn 10 to 15 core heroes to climb ranked ladders effectively, and most of those core heroes are part of the original 102 launch lineup. A lot of pro players in the 2026 International still main original heroes, so you don’t have to pick the newest additions to be competitive. In fact, many top ranked players stick to 3 to 5 original heroes for their main roles, because their kits are well understood and have consistent counterplay options that don’t change drastically between patches.
Common Misconceptions About Dota 2’s Launch Hero Lineup
We’ve seen a lot of wrong claims floating around Dota 2 community forums and TikTok clips in 2026 about the original launch roster, so we’re clearing up the most common ones here. First, no, Invoker was not added after launch. He was part of the original 102 heroes, even though his kit was a little less complex back in 2013 than it is today. Second, there were no completely original heroes at launch, all 102 were ported from the original Warcraft 3 mod. The first completely original Dota 2 hero, Monkey King, was added in 2016, three years after launch.
Another common myth is that only 80 heroes were available for free at launch, and the rest had to be unlocked with paid currency. That’s completely false. Every single Dota 2 hero, from launch to 2026, has been 100% free to play for all players, with no paywalls for any playable content. The only paid items in the game are cosmetic skins, battle passes, and other non-gameplay affecting items, which is another big reason the game has stayed fair and popular for so long. You don’t have to spend a single dollar to access every hero and play competitively at the highest ranks.
Whether you’re asking for a trivia question for your Dota 2 watch party, or you’re just curious about the game’s roots as you learn to play in 2026, knowing how many heroes did dota 2 have on release gives you a little more context for how far the game has come. That original 102 hero lineup built the foundation for every meta shift, every International tournament, and every meme we all love today, and it’s cool to see that so many of those original heroes are still fan favorites over a decade later. If you want to test out the original lineup for yourself, you can even find custom game modes in 2026 that lock the hero pool to the 2013 launch roster, so you can experience what Dota 2 was like on day one.
