The February 2014 trailer for the game shows off a battle between Bayonetta and a masked character identified as one of the last Lumen Sages in the world. Naturally, he and Bayonetta fight, and the trailer reveals that he's almost exactly the same as Bayonetta, in the sense that he has his own variants of Wicked Weaves and summoning. Yep, he can summon the Auditio you fought in the previous game. Oh dear. In response, Bayonetta summons her own monsters to fight back against the massive Auditio, with them fighting each other while the Sage and Bayonetta keep fighting in the foreground. In presumably another battle against him, they are both flying while fighting one another. The background... words can't really do it justice.
In game, the first time the Masked Lumen reveals his powers, i.e. getting shot at point blank range... at which point he activates his own version of Witch Time, Light Speed, and casually brushes the bullets aside like he's more annoyed than anything.
At the end of Chapter 1, Madama Butterfly defeats an angel whose head is on his sword (a Valiance) by grabbing the sword and repeatedly stabbing him with it.
Bayonetta versus the three Glamors at the Gates of Paradiso. The Glamors themselves are impressive, then you start fighting the first one. While riding a piece of building, on the side of a maelstrom. Then you punch the seraph inside the maelstrom with Madama Butterfly and keep fighting him until you emerge from the whirlpool ... and you're before the Gates of Paradiso. Cue two more Glamors joining and you pushing both back before going for the one who stole your little one. You beat it, the other two come back to the rescue, only for you to summon Diomedes, who proceeds to slice and dice the suckers. Awesome.
Before reaching Alraune deep in Inferno, Bayonetta is met with Rodin, and the two proceed to venture towards her palace whilst riding on an Insidious. The kicker? Rodin is perfectly capable of one-shotting every single demon on their path, something no other NPC in the game is capable of.
Just after defeating Alraune, Bayonetta sees The Masked Lumen trying to kill Loki. What does she do? Summon Diomedes and cross Inferno to his rescue while Friendship is playing.
Rosa's entrance, which stuns Bayonetta in silent awe. Badassery is inherited.
The Witch Hunt chapters. You are tag-teaming with Rosa and tearing through entire platoons of angels of all sizes (who are, incidentally, the exact same ones you fought in the first game), even kicking the ass of the four Cardinal Virtues in short order. Then you get your hands on an Umbran Mecha and proceed to down what amounts to an angel battleship! Anyone who played Asura's Wrath will see some familiarities. Also doubles as Heartwarming when you realize Bayonetta was teaming with her mother and enjoying it.
Chapter XV opens with a long fight against a horde of angels right outside a giant clock tower that is soon after blown to bits. This leads to a recreation of the first game's opening sequence, and it's just as glorious here. The game even throws in a boss fight against Loptr on top of that to drive the epicness home.
Balder: Humans need not be told what their will shall be! We can create our world with our own eyes! [...] We may not see our next step. We may stumble, we may fall off the path. But we always move forward. That is the power of man! Bayonetta? Shall we illustrate?
Not as cool as punching Jubileus's soul into the sun but Bayo and Balder summoning a being that looks like Jubileus and Queen Sheba combined and dropkicking Loptr/Aesir was still very nice. And, instead of the sun, we have Jeanne summoning Gomorrah from atop her jet and Loptr/Aesir flailing helplessly as you steer him straight into the demon's mouth ... who proceeds to eat him. Devourer of the Divine indeed.
