This card's effect simulates the type of vehicle it is based on — a submarine that launches a long-range attack before submerging again.
This card's second effect is similar to the first effect of Crystal Beast Emerald Tortoise, which also has a similar basis as just like submarines hide in the water to aid in their concealment, real-life tortoises and turtles can withdraw into their shells in case of a threat (hence, retreating into Defense Position.)
Both of these cards share the same Attribute (being WATER) and have a much higher DEF than their ATK to complement their Defense Position-shifting effects
Coincidentally, both of these cards are owned by secondary protagonists in the Yu-Gi-Oh! GX anime, who have blue hair and wear (or would later in the series) blue articles of clothing. This card is used by Syrus Truesdale (who would be promoted to Obelisk Blue twice, albeit it wouldn't be until he's moved-up to this class rank during Season 4 of GX that he would finally wear their elite attire of the same predominant color.) whereas Crystal Beast Emerald Tortoise is used by Jesse Anderson (whose attire includes a blue above-waist-length jacket with dark blue outlines as well as a in-part, a dark-blue vest while he was possessed by Yubel).
This monster appears in the artwork of Emergeroid Call.

TCG Rulings
Earthbound Immortal: If you control an Earthbound Immortal and no other monsters, your opponent cannot attack you, because they cannot select the Earthbound Immortal as an attack target. (Exception: they can attack with monsters that can attack directly, such as “Submarineroid.”)
Forbidden Chalice: If a monster like “Submarineroid” attacks directly, and “Forbidden Chalice” is activated during the Damage Step, resolve the attack. A replay
