Scales as Malgax was being cocky and was toying around with Ben the entire episode (even with Ben as Atomix), as he doubted any of Ben’s aliens could defeat him, even letting Atomix use his best attack on him, so the punch wasn’t at Malgax’s full force, which if it was Diamondhead would have been dead.

Diamondhead’s Height - 2.3026 meters

Using the square cube law.

Average human height- 1.7 meters

Average human volume- 0.07 m^3

V2 = 0.07 * (2.3026/1.7) = 0.095 m^3

Diamondhead is stated to be a silicon-based lifeform with his crystals being similar to that of a superhard diamond-like substance.

Density of diamond- 3510 kg/m^3

Diamondhead’s weight- 333.45 kg

Timeframe- 5 seconds

The distance of which Galvan B is drawn from Galvan Prime is around three times the distance the Moon is drawn from Earth in Ben 10: Omniverse. This seems accurate, since Galvan B is compared to the largest known moon Ganymede, so the distance between Jupiter and Ganymede should suffice.

Distance between Galvan Prime and Galvan B- 1.070214e+9 meters

Speed- 1.070214e+9 meters/5 seconds = 214,042,800 m/s
