<p>Dr Doom</p>

<p>As a long-time antagonist should be quite interesting, but only if there's a hero (or heroes) that can live to the expectation.</p><p>
</p><p>As a hero, he could be an awesome Daredevil or any character with certain degree in Martial Arts. I'm still pondering who, and more importantly, why.</p><p>
</p><p>I don't think he could match the physicalities of Wolverine (H. Jackman seems irremplazable for me) but he definitely can try the role.</p><p>
</p><p>In any case... I hope to see Keanu very soon aboard of the MCU :)</p>

<p>Wolverine or maybe even moonknight</p>

<p>Wolverine </p>

<p>Iron Fist</p><p>
</p>

<p>Sentry or Kang or Ares (God of War) </p>

<p>Moonknight</p>

<p>Moon Knight would be interesting, maybe Taskmaster</p><p>
