Inspired by this thread, after Zedoshi wondered how a Gun Puppy boss would be at all possible. My mind went to work, and this is what I came up with:
-The boss would have three heads, akin to the gatekeeper of hell Cerberus. You'd have to destroy all three heads to defeat it.
-Each head would have an attack of its own: one would be a spread of status-inflicting bullets, another would have curving streams of fire, and the last would shoot a multitude of rockets. These heads would alternate randomly to attack you. After two heads are destroyed, the last one would essentially go crazy and fire its preferred projectile all over the place.
-It would have a special spinning attack where it goes so fast, it would generate a whirlwind to pull you towards it and knock you away painfully upon contact. (If this on its own is too easy, it can have alternating spike floors around it instead.)
-When the battle begins and each time a head is destroyed, other Gun Puppies will spawn around the edges of the area to add to the chaos.
-When all three heads are destroyed, it would malfunction and try a desperation whirlwind before finally exploding into delicious, delicious rewards.
Sounds difficult, but it's no more merciful than the other bosses in this game so far. Probably a Tier 2 boss.
So that's one of my ideas. I'll now open up the floor to hear what you think would be a good boss for Spiral Knights. There's no guarantee that the devs will put it into the game, of course, but I figured it would be a chance to throw our imaginations around.
I would love to be surprised and am open to anything awesome. I didn't much care for the Royal Jelly but I really love what I've seen of Vanaduke. Haven't killed him yet but also haven't read any strats or anything for him, just been going at him with a friend and learning as we get there. It makes me think of the Zelda bosses I used to adore and I hope they do more along those lines.
