This is semi-old news, but I’ve been busy with college and I’m just now getting to updating the site again.
The new mavericks in Rockman X5 are Crescent Grizzly, Bolt Kraken (most likely Sonic Squid in the English version), Tidal Whale, Shining Hotarunix (a FireFly), Spiral Pegasus, Spike Rosered, Burn T-Rex, and Dark Necrobat. So far, this undoubtedly looks like the most interesting batch of mavericks yet, at least in design and concept.
New reploids include Doglas, Alia (an information source), Life-Saver (repair robot), Signas, and Dynamo.
