Tom dives in front of a laser[]
First off we know this is traveling at light speeds since it bounces off of tom’s eye and is later stated by a future tom to be laser that gave him cancer
Zanta is pretty much the same height as the eddsworld main cast who are british men so 175.3 cm
Zanta 466 px = 175.3 cm
Skull 87 px = 32.72 cm

In this second image for distance between zanta and santa
Skull 142 px = 32.72 cm
Distance 69 px = 15.8991549296 cm

Now a third image for tom’s distance
Santa 424 px = 175.3 cm
Distance 492 px = 203.41 cm

Speed of this laser would be 299,790,000 m/s
So our dodging calc which is (Distance the character moved in meters) x (Speed of projectile in meters/s) / (Distance the projectile was away from the character when he/she started to move in meters)
So 2.0341 * 299,790,000 / 0.158991549296 = 3,835,441,831.34 m/s FTL +
Edd ducks under a laser[]
This is outright stated to be a laser
The distance between him and himself
Edd 186 px = 175.3 cm
Distance 431 px = 406.2 cm

For distance edd moved we need the size of his head
Edd 292 px =175.3 cm
Edd Head 92 px = 55.2315068493 cm

Using a photo editor to overlay the image of edd dodging the laser
Edd head 576 px = 55.2315068493 cm
Edd distance 468 px = 44.875599315 cm

Lasers are 299,790,000 m/s
Using dodging calc from earlier
0.4487559931 * 299,790,000 / 4.062 = 33,119,783.154 m/s Realivistic
Tom and Zanta blow up[]
From hooves to shoulder the average reindeer is 135 cm
Reindeer 28 px = 135 cm

Explosion Diameter 463 px = 2232.32142857 cm

Divide that by two for radius and we get 1116.16071429 cm or 11.16 meters
Using air blast formula (11.16/0.28)^3)/2 = 31658.3658892 grams of tnt or 0.0316583658892 tons of tnt Small Building Level
Tom blows up in the end[]
Edd 33 px = 175.3 cm
I’ll assume where the fire spreads is how far the explosion spread
Fire 186 px = 988.054545455 cm

Divide that by two we get 494.027272728 or 4.94027272728 meters
Using ground formula 4.94027272728 ^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 0.0096903238 tons of tnt Small Building Level
