Humans are under attack! The evil God of Death Thanatos is on a rampage, and it's up to Pit to put a stop to the Underworld Army's path of destruction. Armed with the Power of Flight that was granted to him from the goddess Palutena, Pit sets forth to complete his goal.
In an old abandoned house lives a female ghost with a fetish for photos of terrified people who venture into her abode, and her two spectral male companions who delight in obtaining these images to gain her favor. One dark and stormy night, Sonic and Chip seek refuge in the haunted building to escape from the rain. Seeing this as a perfect opportunity to add a new image to their gallery of terror, the snap-happy spirits leap into action. But while Chip proves a suitable scaredy-cat, the two ghouls may have bitten off more than they can chew when it comes to spooking Sonic...
Both are computer animated shorts (or in the case of Kid Icarus, a series of 3 short episodes) that are based on (or promoting) video games. Personally, I liked Sonic: Night of the WereHog a bit more, but if you like video games and anime based on video games then you should check out both.
These are both CGI shorts involving famous video game characters. They stand alone from their respective series, so you do not need to have played any games to understand the basic plots. If you're a fan of one, I recommend checking out the other.
In the beginning God created the light and the dark, but soon, the powers of light squared off against the powers of dark, and the world was plunged into war. Eventually, seven knights of lights with the power of Shadow rose up and sealed the darkness away. Now, many years later, Nene, the ruler of the Grand Kingdom, is trying to use the power of Shadow to plunge the world into chaos. Looking for other people with the power of Shadow, Nene sends his forces to attack Shu's village; but while defending his village, Shu unleashes the Shadow of Blue Dragon, the most powerful shadow known, and it goes berserk. Can Zola and Jiro, two other Shadow users who oppose Nene, teach Shu how to control Blue Dragon and save the world from chaos?
Kid Icarus is super short and meant to be a promotion for the upcoming game, while Blue Dragon is a very extended complement to the games. While there's plenty of game-based anime out there, Kid Icarus's focus on a single monster battle fits right in with the general tone and feel of Blue Dragon. Neither are very good, but fans of one might like the other.
One day, the brave hunter Kyle and his lady Alita are out hunting creatures when suddenly, a large black dragon appears, kidnapping Alita and killing their companion in the process. Hope lies only with a powerful blue dragon named Blau who is hell-bent on putting a stop to the black dragon's sinister plans. Now, in order to save Alita and prevent further destruction, Kyle must join forces with Blau and stop their opponent from reaching the black tower before it's too late!
Look, comparing Panzer Dragoon's visual quality with Kid Icarus (based on the actual 3D video on the DS, not the quality of screenshots here) is pretty absurd - PD is TEEEERRRIIBLE. That being said, these two are pretty similar: short, generic action, and not really worth watching. Kid Icarus is like watching a trailer (which it kind of is), PD is just painful but hilarious. If you like short action/fantasy tidbits, these are similar. Kid Icarus is clearly WAY better though, visually.
