X is the 24th letter in the Alphablock gang.
X is voiced by David Holt.
Just like Octoblock, he is a superhero; the X Man. He is strong and uses his X-ray vision.
Plusman is X's alter ego. He is red and orange and makes compound words.
- A common running gag is that whenever X uses his x-ray vision, he scans to the right, middle, and left.
- X's letter means 10 in Roman Numerals.
- Although not seen, X keeps bumping his head on the ceiling.
- As seen in Plusman, X dislikes bananas.
Magic E, Plusman
