Card Trivia:Vulnerability Dragon


 * This monster's name is based on system vulnerability; this concept exemplifies every component of this monster's effects and even its card stats.
 * If your opponent controls a monster and you control a Link Monster, you can Special Summon this card (from your hand) in Attack Position. By definition, a vulnerability in IT, is a weakness which can be exploited by a so-called "Threat Actor" (e.g. a hacker) to perform unauthorized actions within a computer system.  Fittingly, the monster your opponent controls can be interpreted as the attacker, whereas the Link Monster you control is the "computer system" to be exploited.  As a result, this monster's Summon is the applicable tool or technique that the attacker posesses to connect to the system's weakness (also know as the attack surface).
 * You can only Special Summon "Vulnerability Dragon" once per turn this way. Naturally it's common sense to address a system vulnerability by upping network security measures aimed in-part at either minimizing or removing the vulnerability in question.  However, the concept of security is a fallible concept--perfection in security doesn't exist and in the case of computing, system manipulations, along with improvements in types of malware and hacking techniques, can create new system vulnerabilities in the future.
 * If Summoned this way: Target monsters you control equal to the number of monsters your opponent controls; destroy them.. Finally, this is the payload of malware, or the malicious action(s) it performs, as in the monster(s) this card can destroy.  However this is also ambiguous--depending on the number of monsters your opponent controls, this monster can either just destroy itself and/or monsters you need on the field--mirroring either the containment, removal or cessation of the malware/attack on the system in progress or the damaging  of computing systems given proper security measures have been undertaken or not and regardless on if the damaging malware/attack is eventually caught and stopped or otherwise.
 * This monster's 100 ATK and DEF, may come from the fact that malware programs and executables are typically low in terms of data size. Furthermore, all computer data thus far is based on binary--1s and 0s.  This monster's DARK-Attribute and Dragon-Type is perhaps based on the notion that viruses (especially the malware kind) and dragons are often depicted as being destructive or villainous in media.
