Ultimate Crab Battle

A Shmup Flash game by Felix Weisner, available here.

The player controls Bobbeh the magical shark and his boy companion (unnamed) in an Underwater Boss Battle fight to the death against their mortal enemy, the Giant King Crab, in the final-est climactic-est ultimate-est final battle to ever come at the end of anything. The titular crab pulls out every stop in this fight, attacking with lasers, swordfish, electrified spikes, helmeted jellyfish, fast-growing coral, and increasingly overelaborate attack sequences, each one sillier than the last. It is, quite simply, a parody of the bombastic, flashy, theatrical Final Boss battles in many recent videogames.

Has nothing to do with this.

In the blue coooorner (Bobbeh & boy tropes):
 * A Boy and His X (inverted)
 * Boss Arena Recovery (the "shoot me" fish)
 * Critical Existence Failure
 * Difficulty Levels
 * Excuse Plot: Bobbeh and his friend are fighting the King Crab to prove that sharks aren't evil; Crabs are.
 * Eye Beams (Bobbeh uses these infrequently)
 * Hammerspace: to an extent. Come on, where DO you store all those rockets and torpedoes?
 * Scoring Points
 * Shout Out: Bobbeh shoots Frickin' Laser Beams from his head.
 * Sweat Drop: The boy makes these while the Giant King Crab makes his entrance.
 * Weaponized Animal

And, in the red coooorner (Giant King Crab tropes): ...But, funnily enough, NOT:
 * Authority Equals Asskicking
 * Big Bad
 * Chainsaw Good:
 * Crazy Awesome
 * Crosshair Aware (his eye beam)
 * Crowning Music of Awesome: the main theme is probably the most epic thing you'll ever hear in a flash game.
 * This theme is actually something out of Code Geass. And the Game Over theme is also from Code Geass: it's "If I Were A Bird".
 * Everything's Squishier With Cephalopods: one special summons a swarm of squids in helmets.
 * Eye Beams (just one giant eye)
 * Giant Enemy Crab
 * Faceless Eye (his eye transformation)
 * Flunky Boss: the Crab has random electric eels coming to shock you occasionally. He also doubles as a Mook Maker himself since a few of his specials summon diverse mooks, and the only attack he will use multiple times in the battle is the summoning of an small walking robot with a separate healthbar which tries to shoot you with plasma bolts.
 * Hammerspace
 * Hey It's That Voice (Mumm-Ra's to be exact.)
 * Humongous Mecha (the AT-AT he summons at the start)
 * Invulnerable Minor Minion (the electric eels)
 * (when he dies)
 * Lightning Gun: averted with his lightning herse... then played perfectly straight with his electric Wave Motion Gun later on.
 * Luck Based Mission: Some of his attacks can become this coupled with the random electic eel appearing. Standing in a spot waiting for his electric herse attack to end? Electric eel comes, no space to dodge, you're dead. Spinning around for your life during the Pearl move? Electric eel comes, no possibility to dodge, you're dead. Trapped between the chainsaw blades? Electric eel comes, no space to dodge, you're dead.
 * Marathon Boss (set aside seven minutes, dear reader)
 * Musical Assassin
 * (or so he says)
 * Nonstandard Game Over: when you kill the Crab, you are immobilized for his ending cutscene, but you do NOT receive invulnerability. Thus, if you kill the Crab but leave one of his walker robot minions alone, you will keep standing in one spot as the Crab begins his monologue and the walker stands right underneath you, blasting you with plasma beams and eventually killing you. This fact has been discovered empirically. You can die during the ending cutscene. I Wanna Be the Guy much?
 * Pull a Rabbit Out of My Hat (one of the ways he summons mooks)
 * Power Crystal (of course, it has to be a power pearl)
 * Psycho Electric Eel
 * Reflecting Laser (the machine gun's orbs)
 * Shout Out - Star Wars (the AT-AT), Rambo (machine gun),
 * Spikes of Doom
 * Story Driven Invulnerability (while he's using a ridiculously long attack, you can't deliver the final blow)
 * Up to Eleven: How many special attacks can be crammed into one boss battle? How wacky can those attacks get? How many culture references can be made by one boss?
 * Wave Motion Gun
 * For Massive Damage
