Dz Deno Roma

dz Deno Roma (dz・デノ・ローマ Doji Deno Rōma) is the boss of Mockstar in the Master System version of Fantasy Zone, and as a secret boss in 3D Fantasy Zone: Opa-Opa Bros. and SEGA Ages Fantasy Zone for Nintendo Switch. It is a long turtle-like creature with a green shell possessing multiple cavities, whereupon blue projectiles are fired from.

Fantasy Zone Strategy
dz Deno Roma's method of offense is very similar to Volanda's, as both fire a hail of bullets from themselves to rain down upon the player, though in dz Deno Roma's case, the projectile quantity is reduced by quite a bit. dz Deno Roma's head is its weak point, and it will occasionally duck its head into its shell to evade fire. The strategy used in the Volanda fight should be repeated here; fire when the head is out, and evade the bullets when it retracts; repeat ad nauseum until it dies. A quicker strategy is to drop the Heavy Bomb when its head first pokes out to instantly take the boss out.

In 3D Fantasy Zone: Opa-Opa Bros. and SEGA Ages Fantasy Zone, it appears as a secret boss if one of two certain conditions are met. The first condition is to start the game from round one without using the Coin Stock feature and accumulate $235,000 or more before you reach the boss, and the second is to destroy all bases in the stage and collect less than $10,000 from them before you reach the boss. If either of these conditions are met, Winklone's eye will appear, but will soon be crushed by dz Deno Roma, initiating the fight. Its behavior is almost identical to its Master System appearance, save for the boss' head popping from its front end to its back. Compared to the Master System version, Dz Deno Roma only takes 5 hits on it's head to kill it. Take it out easily with 5 Smart Bombs while avoiding it's shots.

Trivia

 * dz Deno Roma replaces Winklone from the original arcade version due to hardware limitations (most likely stemming from Winklone relying on multiple sprites to form each of its spinning arms).
 * dz Deno Roma's name is derived from a line in the 1983 Japanese drama television series Stewardess Monogatari. In it, protagonist Chiaki Matsumoto refers to herself as "doji de noroma na kame", or, "a clumsy talentless turtle." The developers took the "doji de noroma" portion of the quote and restructured it to sound like a foreign name.
 * If Master System Mode is on when entering Salfar in Sega Ages Fantasy Zone which replaces Crabumga and Winklone, Dz Deno Roma will appear in red and yellow instead of green and yellow, once again crushing Winklone in the process. It's attacks will also become faster too.
