Eight

Eight is a Numberblock in the original generation.

Appearance
Eight has 8 magenta blocks. He also has 8 dark magenta limbs that look like tentacles, like an octopus. He has a pair of goggles with 4 points on each side, totalling up to 8. He has dark magenta lips too.

Personality
Eight goes by the name "Octoblock", and is courageous and heroic when being Octoblock. Once, he saved One from falling from a tree by catching her and adding with her to make Nine.

Eight also goes by another name, "Octonaughty". As Octonaughty, Eight becomes really naughty and has a high-pitched voice, a green mask and green tentacle limbs.

In Next Gen Blocks
Eight doesn't appear a lot in Next Gen Blocks. His role as "Octoblock" is shown occasionally. His daughter, Septablock, has her own ego, similar to Octoblock.

He appears in episode 10 to defeat Albin, and episode 20 where he was busted down by Sixty-Five (11 - 15).
