Octonaughty is made up of 8 bright magenta/hot pink blocks, with 8 green octopus-like limbs of which he uses six for arms and two for legs (mostly used in a 2x4 arrangement). He wears a purple infinity symbol-shaped mask with 8 spikes, 4 on each side, with a green bandana covering it. He is Octoblock's arch-enemy and villain counterpart, proven by his high-pitched, goofy voice, and everything he does is the reverse of what Octoblock does, as his catchphrase is "Octonaughty, (command)! 8, 7, 6, 5, 4, 3, 2, 1, (said command)!" (however, this only happened in 1 episode). Unlike Octoblock who is brave, heroic and helpful, Octonaughty is very selfish, always coming up with schemes to defeat Octoblock that always fail. He is also rather cowardly, shown when he escapes every time his plans fail. He has a high-pitched, goofy voice and has a very naughty personality. He can't sleep without his stuffed bear. (don't mind the voice, lol ._.)

Blockzilla is a massive, green monster who resembles a cross between a dinosaur and a lizard. She has a rather round-shaped body with two yellow-tinted eyes on top, with small black pupils and green floating eyebrows. She also has olive frills on the sides of her body, and two nostrils. Her main defining feature is the big black lips on her wide, gaping mouth, which resemble the number comparison signs (</>/=). When Blockzilla switches to the equals sign, the top and lower portions of her body become disembodied, with the top part floating. Blockzilla is mostly seen half-buried in the ground, but whenever she isn't in the ground she has green arms and legs with red claws, and a long green tail. Blockzilla loves big things, because that's what she loves to play with. As soon as she sees two numbers, she indicates which number is greater and which is less. She also talks in broken English, referring to herself by her name or "me" instead of "I", as well as using very simple words for verbs. She can act rather immature and childish. (sorry about the voice/image)
