Star Wars had lightsabers before any anime did, but weapons similar to them are quite common in anime, so they’re the topic today.
First of all, they certainly can’t literally be light. Neither a normal beam of light nor a laser stops when it reaches a set length, or blocks other beams from crossing itself.

Some anime have little or no blood in situations where you’d think somebody would be bleeding, but at the other extreme are the ones where people bleed far too much.

Getter Robo is full of things that defy the laws of physics, but it’s not really the physics that we’ll be looking into today. It’s the implications the title robot’s power source has for biology that concerns us.
Getter Rays are called the energy of evolution. (As is Spiral Power from Gurren Lagann, in direct homage to Getter.) They are said to be what originally wiped out the dinosaurs on the surface, and are still harmful to the reptilians of the Dinosaur Empire. Most of the other things they do don’t really have anything to do with evolution at all.

Another one from Dragon Ball. Goku’s transformation into a Great Ape is triggered by the light of the full moon, so “Jackie Chun’s” method of changing him back is to use his Kamehameha to blow up the moon. For how much of a task it is to do that, see “Destroying a planet”. This post is going to be about what would happen to Earth if the moon was destroyed.

As I’ve said before, some anime like to have things so big that the square/cube law says they shouldn’t be able to support their own weight. But weight only applies when there’s gravity, right? So how about giants in space?

Transformers Energon was the terrible English dub of Transformers Superlink, which wasn’t that good to begin with. One infamous line of dialogue from it was “We warped into another galaxy on the outer reaches of the solar system.”.
That’s an extreme example of an issue that a lot of other anime have to a lesser degree; mixing up astronomical terms and/or the scale associated with them. Several series have used “galaxy” like it meant “universe”. Others don’t seem to realize how close a “moon” and a “planet” can be in scale.

This is a topic that was already well-covered in The Physics of Superheroes. But while The Atom and Ant-Man/Giant-Man/Too-Many-Names-Man have size changing as their explicit super power, a lot of anime (and near-anime) characters do it incidentally, as a part of other transformations. Of course, so does the Hulk.
For example, Devilman is considerably taller as the demon Amon than as the human Akira. (Or in Mazinger Z vs. Devilman, much taller.) Well, at least he’s supernatural.
