Anime has a very distinctive stylistic conventions. From just a glance at an Anime on a television the viewer would quickly know it was indeed an Anime. Because Anime is an art form 'Japanese animators began to create their own work by 1915, animation as a commercial art form really got started' (Napier, 2005: 16). Unlike Disney animations which vary from a animation to animation, but hey this blog is not about Disney as a genre ay!
We will start with the the obvious things that grab your attention into thinking an Anime is in fact an Anime. Usually the characters eyes are the most distinctive as they are large and round (See image of Ash Ketcham at the top of the page), this was thought to show more emotion. Another distinction is large hair extravagant hair (See bellow).
There is often thick brush-stroked outlines and this is in reference to when the animation was in comic book form (Manga). Facial Expressions are a big part of Anime as this really shows what mood the character is currently feeling much different to western animation. This is again a reference to when it was in comic book form where the artist had to portray the characters feelings in one still frame with no audio. The facial expressions are usually exaggerated:
Usually an angry character may have a bulging vein or an angry female may materialise mallet (or any other weapon) out of nowhere and smash the person that has irritated them on the head. This is known as hammerspace.
Usually in exciting or tense moments this is emphasised with a flashing background:
In this case Pokemon is mostly about battling Pokemon and so when the battle starts the flashing background suggests the tempo rising.
