Seeing Dosu supporters warms my heart.

"bruh, tf is dosu gonna do for us?"

Now, to answer your question of "what is Dosu gonna do for us?" let's put it this way.

First of all, the standards of who can become a playable character are ridiculously low. If we have Enma (who only had like 2 fight worth of material), Shizuka/Guren/ Yota of all people/other filler characters (filler, that's self explanatory), Chiriku (monk dude who did nothing but get killed by Kakuzu), and Hanabi (who showed up in a flashback and in the Chunin Exams and that's really it, we're not counting her Boruto form) then Dosu should've been in a long time ago. Not to mention the Hebihimes and the Cats are playable characters when they aren't even CANON CHARACTERS FROM NARUTO.

Dosu is technically already playable in game. The asymmetrical nature of his in game graphics implies that he should've been playable early on, and there's images out there of the game's alpha and beta forms, when he was originally a playable unit. Other games by the same developer as Naruto Online also have Dosu as playable, and he's actually a top tier PVP unit in those games.

As a general rule, having more characters within this game leads to a potentially diverse meta and an open sandbox filled with possible creativity with team compositions. Mixing different character effects to make really neat teams. Et cetera. In an ideal world for Naruto Online, we'd get a Dosu with good skills – not meta defining, but strong enough and unique enough that he could hold his own as a choice in a team. Nothing like Zaku the meme unit, but a genuine unit who can add to the diversity of the game meta.

It just doesn't make sense that only Zaku is a playable unit. I don't know why they skipped over Dosu and went for filler characters like Shira, Yota or friggin' Suit alts of existing units (ick) instead.

I've been pushing this topic since the game first came out back in 2016.
